- Update header.templ to load single main.js script instead of 4 separate files
- Remove obsolete header.js and search.js as they are now bundled
- Update Alpine.js event handlers to use standard double quotes
- This completes the ESBuild migration by eliminating inline script loads
The main.js bundle now contains all header, theme, and search functionality
previously loaded separately, improving load performance and maintainability.
- dashboard.templ: Replaced individual script tags with single main.js import
- admin_users.templ, custom_section.templ: Minor formatting/cleanup
- docs.templ: Updated script imports (excluded from Alpine conversion per user request)
- api.ts, docs.ts, password_validation.ts: Minor updates for compatibility
Updated ESBUILD_MIGRATION_PLAN.md to reflect:
- Phase 1 completion status
- New Alpine.js conversion work
- Remaining templates status (docs.templ excluded per user request)
Added Alpine.global() registration to enable template access to functions:
- admin.ts: Added Alpine for scan, stats, and settings functions
- api-explorer.ts: Already had Alpine (kept as is)
- bookshelf.ts: Added Alpine for library/bookshelf interactions
- collections.ts: Added Alpine for collection management
- conflicts.ts: Added Alpine for conflict resolution
- device-management.ts: Added Alpine with event delegation for dynamic content
- header.ts: Added Alpine for theme dropdown and user menu
- library.ts: Added Alpine registrations
- linking.ts: Added Alpine registrations
- queue.ts: Added Alpine for queue operations
- search.ts: Added Alpine registrations
- themeDropdown.ts: Added Alpine for theme switching
Each module now exports functions both traditionally and via Alpine.global() for template access.
Removed 470 lines of inline JavaScript from devices.templ:
- Extracted all device management functions to device-management.ts
- Added x-data="devices" and x-init for event delegation
- Converted static onclick handlers to @click
- Dynamic content (edit/delete mapping buttons) uses data attributes
- Event delegation handles clicks on dynamically generated buttons
The device-management.ts already had the updated loadShelfMappings() function with data-action attributes for event delegation.
- Modified package.json build:ts to copy htmx.min.js from node_modules to web/static/
- This fixes the 404 error for /static/htmx.min.js that occurred after ESBuild migration
- Added htmx.min.js to static files
See ESBUILD_MIGRATION_PLAN.md for migration context.
Remove outdated migration documentation and regenerate template after
script tag cleanup.
Changes:
- Delete ECHO_V5_MIGRATION.md: Obsolete migration plan, superseded by
ESBUILD_MIGRATION_PLAN.md
- Delete esbuild-setup.md: Incomplete setup document, replaced by
comprehensive migration plan
- Regenerate templates/collections_templ.go: Remove collections.js
script tag (now using main.js bundle)
Template update:
- Removed <script src="/static/collections.js"> from template
- Now uses single main.js bundle (ESBuild output)
- Line number adjustments in generated Go code
Cleanup of obsolete documentation as part of ESBuild migration.
Create detailed migration plan for transitioning from window globals
to ES modules + Alpine.js architecture. The plan addresses all gaps in
the previous setup document and provides incremental migration phases.
Changes:
- Add ESBUILD_MIGRATION_PLAN.md: Complete 46KB guide with 6 phases
- Add ESBUILD_README.md: Quick reference for starting migration
- Add ESBUILD_IMPORT_FIXES.md: Summary of import corrections
- Archive ESBUILD_SETUP_OLD.md: Preserve previous incomplete plan
Key improvements:
- ES module exports for TypeScript→TypeScript dependencies
- Alpine.js ONLY for template bridge (not internal TS)
- Incremental migration with no legacy code
- Clear testing and rollback procedures
- File-by-file checklists for each phase
The plan corrects critical issues:
- 193+ internal window reads → proper ES imports
- Function wrapping (themeDropdown.ts) → restructured
- Dual exports: ES modules + Alpine namespaces
- SSR-first with progressive enhancement
Total scope: 21 TypeScript files, 27 template files, ~1700 lines of
detailed instructions.
Related: Issue #ESBuild-Migration
Add Alpine.js reactive framework for client-side state management, replacing
(window as any) pattern with modern component-based architecture.
Build configuration changes:
- package.json: Update build scripts to use main.ts as entry point
- Change from web/src/*.ts glob to web/src/main.ts
- Update all build:ts scripts to use --outfile instead of --outdir
- Add build and dev scripts for complete build process
- Build now produces single main.js bundle (~120-150KB minified)
Alpine.js setup:
- web/src/alpine.ts: Create Alpine initialization module
- Extend Window interface with Alpine type declaration
- Initialize Alpine and attach to window for DevTools
- Re-export Alpine for other modules to register globals/components
Frontend module updates:
- web/src/main.ts: Import alpine.ts last to initialize framework
- web/src/toast.ts: Add Alpine import (ready for migration to Alpine.global())
Architecture:
- Alpine.js for client-side state (modals, dropdowns, theme switching)
- HTMX for server calls (existing pattern, unchanged)
- Hybrid approach: Alpine reactive components + HTMX form submissions
Next steps (see esbuild-setup.md for detailed guide):
- Migrate TypeScript files from (window as any) to Alpine.global()
- Update 27 templates to use @click instead of onclick
- Add x-data/x-show for stateful UI components
Note: web/src/docs.ts has pending changes with Lunr imports that need
separate handling (data files don't exist yet - backend API search planned,
see DOCS_SEARCH_IMPLEMENTATION.md)
Comprehensive update to esbuild-setup.md with Alpine.js integration guide
for replacing (window as any) pattern with modern reactive framework.
Key changes:
- Add Alpine.js as recommended approach over vanilla event listeners
- Include Phase 2: TypeScript Alpine registration patterns
- Update Phase 3: Template changes with @click and x-data examples
- Add Phase 5: Step-by-step TypeScript migration with exact line numbers
- Fix toast.ts, api.ts, storage.ts examples to match actual code structure
- Include troubleshooting for Alpine-specific issues
- Add migration checklist and quick reference guide
Architecture decisions:
- Alpine.js for client-side state (modals, dropdowns, theme)
- HTMX for server calls (existing pattern, keep unchanged)
- Hybrid approach: Alpine reactive components + HTMX forms
- Bundle Alpine with ESBuild (~15KB gzipped)
Template updates (27 files):
- Replace onclick="func()" with @click="func()"
- Add x-data for stateful components
- Use x-show/x-transition for modals and dropdowns
- Keep HTMX form submissions unchanged
TypeScript migrations:
- Priority 1: Core utilities (toast.ts, api.ts, storage.ts, events.ts, dom.ts)
- Priority 2: Stateful components (header.ts themeDropdown, woodPaneling.ts)
- Priority 3: Page-specific functions (collections.ts, devices.ts, etc.)
- Register functions with Alpine.global() or Alpine.data()
Testing and verification:
- Alpine DevTools for debugging reactive state
- Build step: esbuild --run scripts/build-docs-search.ts
- Verify no 404 errors for missing .js files
- Test all 151 onclick handlers work with @click
Bundle size: ~130KB minified (~40KB gzipped) with Alpine included
Browser support: ES2020 (Chrome 80+, Firefox 72+, Safari 13.1+)
Document is now 1,812 lines with comprehensive step-by-step instructions
for migrating from (window as any) exports to Alpine.js components.
Minor updates to clarify project guidelines:
Testing section:
- Correct test_helpers.go filename reference (test_helpers_test.go)
- Clarify integration test requirements (cmd/server/tests) vs all tests
API Changes section:
- Change 'Bruno tests' to 'Bruno requests' for clarity
- Specify integration test files (cmd/server/tests) in documentation workflow
Documentation section:
- Update 'Bruno OpenCollection YAML tests' to 'Bruno OpenCollection YAML requests'
These are documentation clarifications only - no code changes.
Ensures consistency between guidelines and actual project structure.
Add comprehensive implementation plan for full-text documentation search
using backend API endpoint instead of build-time Lunr index.
Changes:
- Create DOCS_SEARCH_IMPLEMENTATION.md with complete implementation guide
- Backend: internal/docs/search.go with SearchDocuments method
- Backend: HTTP handler for /api/docs/search endpoint
- Frontend: Update docs.ts to use API instead of client-side Lunr
- Testing: Unit tests (search_test.go) and integration tests (docs_search_test.go)
- Bruno: Add Search Docs.yml for API contract testing
- Documentation: API docs at docs/developer/api/docs/search.md
Key features:
- Full-text search across 152 markdown documentation files
- Case-insensitive matching with snippet extraction
- RESTful API endpoint (no build step required)
- Follows PROJECT_GUIDELINES.md (procedural code, table-driven tests)
- Removes Lunr dependency from package.json
- Consistent with existing /api/media-items/search pattern
Estimated effort: 3-4 hours
Testing strategy: Unit tests + integration tests + Bruno YAML
Replace echo's c.File() with standard library http.ServeFile() in the
ServeFile handler. This provides more reliable static file serving and
better handles edge cases in file delivery.
Remove the script tag for collections.js which is no longer needed as
functionality has been moved to the bundled main.js.
Fix bulk-remove button onclick handler from removeSelectedBooks() to
removebooksToAdd() to match the actual function name.
Update header.js and search.js to reflect the new esbuild build pipeline.
The header.js file is now minified by esbuild instead of the previous
setup, and both files benefit from esbuild's tree-shaking and bundling.
Configure TypeScript to use ES2020 modules with bundler resolution to work
properly with esbuild. Enable source maps for better debugging and update
module resolution strategy for the new build pipeline.
Changes:
- Set module to ES2020 (was "none")
- Add moduleResolution: "bundler" for esbuild compatibility
- Enable sourceMap: true for development debugging
- These changes align TypeScript compilation with the esbuild bundler setup
Remove minified JavaScript libraries that were previously downloaded during
postinstall (htmx.min.js, highlight.min.js, lunr.min.js, lunr-flex.min.js).
These are now bundled via esbuild from npm packages.
Update Dockerfile to remove the now-unnecessary postinstall npm script execution,
streamlining the container build process.
Replace the postinstall script that downloaded minified JavaScript libraries
(htmx, highlight.js, lunr) with proper npm package management and bundling
using esbuild. This provides better dependency management, smaller bundle sizes
through tree-shaking, and improved build times.
Changes:
- Add htmx.org, highlight.js, lunr, and alpinejs as npm dependencies
- Replace tsc with esbuild for faster TypeScript compilation and bundling
- Add esbuild to devDependencies
- Update build:ts script to use esbuild with bundling and minification
- Add build:ts:dev script for development builds without minification
- Add build:ts:watch script for watch mode development
- Remove postinstall script that downloaded external JS files
- Add esbuild-setup.md documentation for the new build setup
- Create web/src/main.ts as the new entry point for bundled JavaScript
This modernizes the frontend build pipeline and reduces reliance on external
CDNs during the build process.
- Remove createTestMediaItem helper function and replace with createTestMediaItemID
- Update TestWebSocketProgressBroadcast to use simplified helper
- Add read deadline and initial message read in TestWebSocketUserScopedBroadcast to properly consume initial connection messages
- This reduces code duplication and improves test reliability by properly handling WebSocket connection setup
Replace default CORS middleware with explicit CORS configuration in test
server setup to align with production security settings. This ensures test
environment matches production behavior and prevents potential CORS-related
test failures.
Changes:
- Replace echomiddleware.CORS() with echomiddleware.CORSWithConfig()
- Configure allowed origins, methods, and headers explicitly
- Set AllowCredentials to false for test environment
- Add ExposeHeaders for Content-Length
This maintains consistency with the CORS configuration applied to the main
server in commit fb05c49.
Enhanced the responseWriter wrapper to properly capture HTTP status codes
by implementing WriteHeader method and storing status code in the wrapper
struct. This ensures accurate status logging in request traces.
Changes:
- Added status field to responseWriter struct to track HTTP status codes
- Implemented WriteHeader method to capture status when written
- Added Hijack method pass-through for WebSocket/upgrade support
- Updated request logging to use captured status from recorder instead of
accessing Echo's internal Response object
This fix addresses potential issues where status codes were not being
properly captured in request logs, particularly for error responses and
non-2xx status codes.
Clean up internal/router/router.go by removing:
- echomiddleware import that was no longer referenced
This change reduces unused imports and improves code hygiene. The middleware functionality is either handled elsewhere or was migrated to different implementations.
Remove legacy test files that are no longer used:
- cmd/server/tests/library_test_comprehensive.go: Comprehensive library endpoint tests
- cmd/server/tests/test_helpers.go: Test server setup and device test helpers
- cmd/server/tests/test_helpers_db.go: Database verification utilities
These files appear to be superseded by newer test infrastructure or were part of a test reorganization. Removing them reduces codebase maintenance burden and eliminates confusion about which test files are currently active.
Replace default CORS middleware with explicit configuration to properly
control cross-origin access. This update defines allowed origins, methods,
headers, and credentials for improved security and API accessibility.
Configuration changes:
- Allow all origins (*) for development flexibility
- Support standard HTTP methods (GET, POST, PUT, DELETE, OPTIONS)
- Expose Content-Length header for response inspection
- Disable credentials to simplify authentication flow
Rename test helper files from .go to _test.go suffix to comply with
Go testing conventions. This ensures proper test file recognition by
the Go toolchain and improves build organization.
- library_test_comprehensive.go → library_test_comprehensive_test.go
- test_helpers.go → test_helpers_test.go
- test_helpers_db.go → test_helpers_db_test.go

Changes in auth.go, library.go, scanner.go, sync.go, helpers.go:
- Update handler function signatures to *echo.Context
- Ensure consistent type usage across all route handlers
All routes now properly implement Echo v5's middleware and handler patterns.
- Add http.Server field to App struct for explicit server management
- Add StartServer() method to create and start HTTP server
- Replace echo.Close() with http.Server.Shutdown() in Shutdown()
- Update import from echo/v4 to echo/v5
Changes:
- New() initializes server field as nil
- StartServer() creates http.Server with Echo as handler
- Shutdown() uses http.Server.Shutdown() with context timeout
- Removed deprecated echo.Close() call (v5 API change)
This provides better control over server lifecycle and graceful shutdown.
- Update github.com/labstack/echo from v4 to v5
- Update github.com/labstack/echo-jwt to v5

- Legacy plan is no longer relevant after Echo v5 migration
- Consolidates documentation into single migration guide
The TestWorker_SetFoldersJob test was submitting a set folders job without
first registering the folder with the library through the HTTP API. This caused
the job to fail because the folder wasn't properly tracked.
Changes:
- Call addFolderToLibrary before submitting the set folders job
- Ensures the temporary test directory is properly registered with the library
- Aligns test behavior with actual API workflow where folders must be added first
- Remove unused 'bytes' import that was causing linting issues
- Comment out TestWebSocketUserScopedBroadcast test temporarily
- The test was checking WebSocket broadcast scoping per user but needs review
- Keeps the test code for reference while preventing it from running
- Remove debug printf statements from media scanner and worker
- Remove unused debug tracking variables (filesSeen, filesProcessed)
- Fix directory walk logic to properly scan the root directory itself
(previous implementation would skip the root path entirely)
Clean up production code by removing debug artifacts and improving
the directory scanning logic to handle root-level directories correctly.
- Update ListMediaItems calls to include required Limit and Offset parameters
- Change Enqueue() to EnqueueJob() to match updated worker API
- Add error assertions for job enqueue operations with descriptive messages
- Ensure all database queries use proper pagination parameters
This ensures tests properly validate error conditions and use the latest worker service API.
Worker improvements:
- Add strongly-typed result structs for all job types
- Replace map[string]interface{} with specific result types
- Add JSON tags to JobResult for proper API serialization
- Fix processJob to handle different result types correctly
- Improve directory scan job with proper library folder resolution
- Add debug logging for scan operations
Media scanner improvements:
- Add nil checks for database in GetPollInterval and GetAutoScanEnabled
- Fix pdfcpu API call signature (add validateOnly parameter)
- Add debug logging for scanDirectory with file counters
- Improve error handling and reporting
Test fixes:
- Fix default poll interval expectation from 30s to 60s

watcher, testing directory creation, modification, and deletion events
with proper cleanup
- media_scanner_test.go: Unit tests for MediaScanner including:
- Scanner initialization and configuration
- Directory walking and media file detection
- Library management and duplicate detection
- Import job creation and queue processing
These tests verify the core file watching and media scanning behavior
to ensure reliable import operations.
Extract health check logic into GetHealth method on Config struct and
integrate with Worker service for accurate scan status reporting.
Changes:
- Move health check handler from inline function to Config.GetHealth()
- Add Worker field to Config struct for dependency injection
- Wire Worker into main server dependencies
- Report actual scan_in_progress status using Worker.HasActiveScans()
- Report actual active_jobs count using Worker.GetActiveJobCount()
This provides more accurate health monitoring by checking the real state
of background jobs rather than returning static placeholder values.
- Add Priority field to Job struct for future job prioritization
- Add HasActiveScans() method to check if any scans are currently running
- Add GetActiveJobCount() method to count running and pending jobs
- Remove unused JobTypeSync constant
These changes enable more accurate health check reporting and prepare
for future job priority queue implementation.
- Return actual database error message instead of generic "unavailable"
- Add scan status information to healthy response (scan_in_progress, active_jobs)
- Maintain backward compatibility while providing more actionable diagnostics
- Use map[string]interface{} to support nested scan status structure
These changes improve observability by providing administrators with
specific error messages and scan status information, making it easier
to diagnose issues and monitor system state.
- Add SettingsCache with TTL-based invalidation (30 seconds)
- Cache scan_poll_interval_seconds and auto_scan_enabled settings
- Reduce database queries from every poll/check to once per TTL period
- Improve error handling with proper fallback values
- Simplify boolean parsing with strings.ToLower for consistency
This optimization reduces database load when checking scan settings,
which occurs frequently during media scanning operations.
Pass ConnectionManager to Worker constructor to enable WebSocket
broadcasting capabilities. Updated:
- main.go: server initialization
- test_helpers.go: test setup
- commonhandlers.go: handler initialization
This change enables Worker to broadcast job updates to connected clients.
- Add WebSocket connection for scan progress updates
- Display live progress bar and file count during scans
- Handle scan_complete and scan_error messages
- Store polling interval in module variable for cleanup
- Expose stopScanStatusPolling function for manual control
Replaces or supplements HTTP polling with push-based updates for
better UX and reduced server load.
- Add UserID field to Job struct for tracking job ownership
- Broadcast scan progress updates to user's WebSocket connections
- Send real-time updates during scanning (progress, files scanned, new items, errors)
This allows the frontend to display live scan progress without HTTP polling.
Scanner now associates scan jobs with requesting user for targeted updates.
Add new message type constants for real-time scan progress updates:
- MessageTypeScanProgress: broadcast progress during scanning
- MessageTypeScanComplete: notify when scan completes
- MessageTypeScanError: report scan errors
These enable frontend to receive live scan updates instead of polling.
Fix incorrect struct tags for Page, TotalPages, and PageY fields.
Previously used 'int' tag instead of proper JSON field names,
which would cause serialization issues.
- Replace event queue with dirty directories tracking (Jellyfin approach)
- Add file stability checking to wait for file writes to complete
- Add initial scan on startup to detect existing files
- Integrate with Worker job queue for directory scanning
- Change WatchChanges to return error and use atomic.Bool for state
- Add scan_mutex to prevent concurrent scans
- Add Close method with proper cleanup of resources
- Enhance polling with configurable interval
- Add WorkerInstance global singleton for global access
- Add new job types: import, convert, thumbnails, backup, analytics, sync
- Add Enqueue method for non-blocking job submission
- Add job processors for each new job type:
- processImportJob: OPDS and Calibre import support
- processConvertJob: EPUB to KEPUB conversion
- processThumbnailsJob: Cover thumbnail generation
- processBackupJob: Database backup functionality
- processAnalyticsJob: Library and system statistics
- processDirectoryScanJob: Directory scanning for media scanner
- Add helper getTopN function for analytics
- Add JobsHandler with CreateJob and GetJobStatus endpoints
- Add jobs router with POST /api/jobs and GET /api/jobs/:jobId routes
- Integrate JobsHandler into main server and router config
Fixed issue where Phase 1 tried to add job types that were already added in Phase 0.5.
Changes:
1. Step 1.1 - Updated title from 'Add All Job Type Constants' to 'Add NEW Job Type Constants'
- Now shows current state after Phase 0.5 (JobTypeScan, JobTypeSetFolders, JobTypeDirectoryScan)
- Only adds NEW Phase 1 job types: Import, Convert, Thumbnails, Reindex, Backup, Analytics, Sync
- Clarifies that JobTypeScan, JobTypeSetFolders, JobTypeDirectoryScan were added in Phase 0.5
2. Step 1.2 - Updated title from 'Add Job Handlers to Switch Statement' to 'Add NEW Job Handlers to Switch Statement'
- Now shows current state after Phase 0.5 (handlers for Scan, SetFolders, DirectoryScan)
- Only adds NEW Phase 1 handlers for the new job types
- Clarifies that existing handlers were added in Phase 0.5
Impact: Developers now have clear guidance on which job types/handlers to add in each phase, avoiding confusion and potential merge conflicts.
Critical rewrite to fix broken hybrid approach that tried to merge two incompatible systems.
PROBLEM WITH PREVIOUS APPROACH:
- Tried to use job queue AND direct scanning simultaneously
- Created job parameters that didn't match handler expectations
- Referenced non-existent activeScans map
- Never-initialized worker field in MediaScanner
- performInitialScan() bypassed job queue
- Like building a car with parts from two different manufacturers
CLEAN ARCHITECTURE:
- Job queue handles concurrency control ONLY
- Scanner handles all scanning logic
- Global WorkerInstance provides access (no circular dependency)
- Simple scan_mutex for double-protection
- Clear separation of concerns
KEY CHANGES:
1. MediaScanner struct:
- Removed: worker *Worker field (circular dependency)
- Removed: activeScans map (too complex)
- Fixed: fileStability map[string]*atomic.Bool (was value, now pointer)
- Added: scan_mutex sync.Mutex (simple, effective)
2. Job queue integration:
- processDirtyDirectories() submits jobs to WorkerInstance
- Job parameters: {directory: dirPath, db: s.db}
- Added JobTypeDirectoryScan constant
- Added processDirectoryScanJob() handler in Worker
- performInitialScan() submits jobs (not direct calls)
3. Worker changes:
- Added WorkerInstance *Worker global variable
- Added Enqueue() method (non-blocking with fallback)
- processDirectoryScanJob() creates scanner, calls scanDirectory()
PRESERVED FROM PHASE 0.5:
- Directory watching with dirty dirs tracking
- File stability checks (Audiobookshelf approach)
- Smart event merging (Jellyfin approach)
- 10-second batch processing
- 60-second polling fallback
ADDED FROM PHASE 1 ROBUSTNESS:
- Job queue for concurrency control
- Test isolation
- Fixed default values (30s → 60s)
RESULT:
- No parameter mismatches
- No non-existent fields
- No memory leaks
- Clean separation of concerns
- Best of both worlds without the complexity
CRITICAL FIXES (would cause test failures):
1. Integration test timing: 5s → 12s
- Test waited 5s but implementation uses 10s batch delay
- Would fail intermittently detecting all 20 files
2. Race condition in fileStability map access
- Lock released between check and insert (lines 342-352)
- Concurrent calls could create duplicate map entries
- Fixed by holding lock during entire function
3. Missing concurrency protection in scanDirectory()
- Multiple scans of same directory could run simultaneously
- Could cause race conditions in fileStability map
- Fixed with activeScans map to prevent duplicate scans
MAJOR FIXES (production issues under load):
4. Unbounded goroutine spawn
- Spawns unlimited goroutines for directory scans
- 100 changed directories = 100 concurrent scans = 1000s of goroutines
- Fixed with semaphore limiting concurrent scans to 10
- You correctly identified this as the same problem Phase 1 job queue solved
5. Memory leak in fileStability map
- Entries never cleaned up if waitForFileStability() called concurrently
- Fixed by proper lock pattern and cleanup on all code paths
6. No initial scan of root folders
- Only watches for NEW changes, misses existing files
- Fixed by adding performInitialScan() function
MEDIUM FIXES (edge cases / code quality):
7. Removed unused batchTimeout variable
- Was declared but never actually used
8. Completed smart event merging
- Added sibling directory consolidation logic
- Prevents redundant scans of sibling folders
9. Clarified subdirectory handling
- Updated comment to explain subdirs trigger own events
- scanDirectory() doesn't walk into them (by design)
10. Added cleanup on shutdown
- New Close() method cleans up all maps
- Waits for active scans with 5-second timeout
11. Test timing: 11s → 15s
- Prevents flaky tests under load
12. Added database error handling
- Checks libraryID.Valid before scanning
- Handles orphaned folders gracefully
NEW CODE ADDED:
- scanSemaphore chan struct{} - limits concurrent scans to 10
- activeScans map[string]bool - prevents duplicate scans
- activeScansMu sync.Mutex - protects activeScans
- performInitialScan() - scans root folders on startup
- Close() method - cleanup and graceful shutdown
ARCHITECTURAL IMPROVEMENT:
- Semaphore pattern (from Phase 1 job queue) applied at directory level
- Higher concurrency limit (10 directory scans vs 3 library scans)
- Prevents resource exhaustion while maintaining parallelism
- All map entries properly cleaned up (no memory leaks)
- Graceful shutdown with timeout

Add real-time synchronization for collection book removal:
- Extract user ID from context for targeted broadcasts
- Broadcast 'collection_updated' message to user's other devices
- Includes collection_id, action, and book_id in message payload
This ensures that when a user removes a book from a collection,
all their connected devices (browser tabs, mobile apps, etc.)
receive real-time updates via WebSocket.
Consistent with existing AddBooks and BulkRemoveBooks operations
which already use BroadcastToUser for synchronization.
Remove completed implementation plans that have been superseded:
- COLLECTION_LIBRARY_FILTERING_PLAN.md (library filtering feature completed)
- IMPLEMENTATION_COLLECTION_FIX.md (collection detail fix implemented)
These plans were for features that have already been implemented
in recent commits. Keeping only current/future planning docs.
This commit adds comprehensive functionality for filtering collections by library,
improves WebSocket real-time updates with user activity detection, and adds
extensive test coverage.
## Core Features
### Collection Library Filter
- Added library_id parameter to media-items search API
- Collections can now be filtered by specific library
- Toggle UI component for enabling/disabling library filter
- Default state is "checked" when library_id is present
- Consistent behavior across partial and fuzzy search modes
### WebSocket Auto-Reload Mitigation
- Added user activity detection to prevent disruptive page reloads
- Checks if user is actively typing in INPUT/TEXTAREA/SELECT elements
- Skips auto-reload when user is interacting with form elements
- Toast notifications still show for awareness
- Prevents data loss during editing operations
## Implementation Changes

- internal/handlers/media.go: Enhanced search with library_id parameter validation
- internal/handlers/collections.go: Updated collection handlers with library filtering
- internal/sync/websocket.go: Improved broadcast mechanism with user-scoped updates
- internal/router/frontend.go: Pass libraryID to collection templates
### Frontend
- templates/collections.templ: Added library filter toggle UI component
- web/src/collections.ts: TypeScript implementation with WebSocket integration
- templates/collections_templ.go: Generated template code
### Testing
- cmd/server/tests/search_test.go: Added TestCollectionSearchLibraryFilter
- cmd/server/tests/websocket_test.go: Added TestWebSocketUserScopedBroadcast

## Testing
### Integration Tests
- Library filter tests verify correct filtering across multiple libraries
- Invalid library_id tests ensure proper error handling
- WebSocket tests verify user-scoped broadcast behavior
- User A no longer receives User B's collection updates
### Manual Testing Scenarios
- Open collection in multiple tabs - updates propagate correctly
- Type in search box while another tab adds books - no disruptive reload
- Add/remove books from collection - toast notifications appear
- Toggle library filter - results update dynamically
## Technical Details
- WebSocket broadcasts are now user-scoped for privacy
- Active element detection uses tagName and contenteditable attributes
- Library ID validation uses UUID format checking
- Progressive enhancement maintained - page works without JavaScript
- All changes follow PROJECT_GUIDELINES.md conventions
- TypeScript only for frontend logic
- TailwindCSS only for styling
- Procedural programming style throughout
## Breaking Changes
None - all changes are additive and backward compatible.
This document outlines the plan to fix the broken /collections/:id page
which has an inline JavaScript bug, and add library_id support to the
search API.
Key changes planned:
- Remove 265+ lines of inline JavaScript from collections.templ template
- Add minimal TypeScript module (~180 lines) in web/src/collections.ts
- Add optional library_id parameter to SearchMediaItems API endpoint
- Add library filter toggle UI to the Add Books modal
- Update template to accept libraryID parameter
The implementation uses a hybrid approach: minimal TypeScript for
client-only features while maintaining HTMX-like patterns for CRUD
operations. This reduces maintenance burden and improves code
organization.
Steps detailed:
1. Update Search API to accept optional library_id parameter
2. Add library_id filter to SQL query if not present
3. Remove inline JS from template, add data attributes
4. Add toggle UI for filtering books by library
5. Add TypeScript functions for modal, search, and book management
6. Update handler to pass libraryID to template
7. Update template function signature
Testing checklist included to verify:
- Page loads without JS errors
- Library filter toggle visibility
- Search results with/without library filtering
- Add/remove books functionality
- Client-side search filtering
The GetPreferences API was returning 404 when no preferences existed
for a library, breaking the dashboard settings modal. Now returns
default preferences (empty hidden_collections, empty collection_order,
20 items_per_section) when no preferences are found, matching the
behavior of the frontend dashboard page.
- Update TestGetViewAllURL_SystemCollections to use collectionID and libraryID parameters
- Test both with and without library_id in URL
- Update TestBuildSections_ConvertsServiceTypesToHandlerTypes expected values
- All collections now link to /collections/{id} (system and user treated equally)
- Add library_id parameter to BuildSections and getViewAllURL functions
- Update dashboard handler to pass libraryID when building sections
- Add library_id query param support to collection detail page handler
- When library_id is provided, filter collection items by that library
- When no library_id, show all books (backward compatible)
- Reuses GetCollectionItemsForDashboard query for filtered results
- Preserves context when navigating from dashboard to collection detail
Add comprehensive step-by-step plan for implementing library-aware
filtering on collection detail pages.
Purpose:
- Preserve dashboard context when navigating to collection details
- Support both filtered (single library) and unfiltered (all libraries) views
- Maintain backward compatibility with existing URLs
Plan includes:
- Detailed code changes for dashboard.go, frontend.go, dashboard_test.go
- Line-by-line modifications with before/after code snippets
- Implementation order with 10 steps
- Testing checklist for verification
- Documentation requirements
Follows PROJECT_GUIDELINES.md:
- No cascading fix-up edits
- Sequential implementation order
- Post-edit verification steps
- Test-driven approach with additions to dashboard_test.go
- Documentation updates for user-facing feature
This is a planning document only - no implementation changes yet.
Ensure consistent JSON responses by converting nil slices to empty arrays
in the GetPreferences handler. This prevents null values from being
returned to the client for hidden_collections and collection_order fields,
making the API response more predictable and easier to consume.
Update RestoreSystemCollection handler to support form-encoded requests from HTMX:
- Add 'form' struct tags to CollectionName and ResetType fields to enable binding
from both JSON payloads and form submissions (required for HTMX compatibility)
- Add conditional HTMX redirect handling that sets HX-Redirect header when
the request originates from HTMX, directing users to /collections after
successful restoration
This change enables the system collection restore functionality to work seamlessly
with HTMX-based modal forms, improving the user experience by providing proper
navigation after the restore operation completes without requiring JavaScript
redirect logic.
Add *.map pattern to .gitignore to exclude JavaScript sourcemap files
from version control. These files are generated during the build process
and are not needed in the repository, matching the existing pattern for
TypeScript declaration maps (*.d.ts.map).
This prevents accidentally committing generated sourcemap files like
collections.js.map that provide debugging information but are not
necessary for deployment or source control.
Add comprehensive documentation tracking the HTMX Server-Side Rendering
implementation for the Collections page.
Document contents:
- Summary of completed implementation (March 2025)
- Detailed list of all files created and modified
- Step-by-step workflow for each CRUD operation
(Create, Edit, Delete, Restore System Collection)
- Verification instructions
- Key discoveries and lessons learned:
* Templ syntax limitations in conditionals
* Route registration order requirements
* HTMX fragment theming inheritance
* Color handling best practices
* Browser caching considerations
Purpose:
- Historical record of implementation approach
- Reference for future developers
- Documentation of project patterns and conventions
- Guide for troubleshooting similar features
Add comprehensive TypeScript utilities for collections page functionality.
1. HTMX Authentication (setupHTMXAuth):
- Adds Authorization header to all HTMX requests automatically
- Listens for htmx:configRequest event on document.body
- Injects Bearer token from localStorage
- Eliminates need for hx-headers attributes on individual elements
2. Smart Card Navigation (navigateToCollection):
- Implements event delegation to distinguish button clicks from card clicks
- Checks event.target to determine what user clicked
- Returns early if button clicked (lets HTMX handle button actions)
- Navigates to collection detail page only when card body clicked
- Uses data-href attribute for navigation target
3. Color Selection Helpers:
- selectColor(): Updates hidden input and visual selection state
- closeCollectionModal(): Removes modal from DOM after HTMX swap
- initColorSelection(): Applies border color classes to collection cards
using borderClasses mapping (blue→border-blue-500, etc.)
4. Icon Picker with Search:
- Hardcoded iconData object: 30 emojis with searchable keywords
(e.g., "📚": ["book", "books", "library", "read", "reading"])
- populateIconGrid(): Dynamically generates icon buttons from iconData
- selectIcon(): Updates hidden input with selected emoji
- filterIcons(): Real-time search filtering by emoji OR keywords
- showAllIcons(): Clears search filter
- initIconSelection(): Auto-initializes after HTMX modal swap
(listens for htmx:afterSwap event on #modal-container)
5. HTMX Modal Initialization:
- setupHTMXModalInit(): Listens for modal loads via HTMX
- Auto-initializes icon picker when modal content swapped into
#modal-container
All functions exported to window object for onclick attribute access.
Auto-initializes on DOMContentLoaded or immediately if DOM ready.
Pattern consistency:
- Follows same pattern as toast.js (global exports, auto-init)
- Uses TypeScript type annotations
- No OOP (functional style per project guidelines)
- Server-side rendering with HTMX (no AJAX data fetching)
Add auto-generated Go code for new modal templates:
- collection_modal_templ.go (from collection_modal.templ)
- restore_system_collection_modal_templ.go (from restore_system_collection_modal.templ)
These files are generated by templ compiler and contain the Render()
implementations. Do not edit manually.
Regenerate with: templ generate
Add two new template components:
1. CollectionModal(collection CollectionData)
- Reusable modal for both creating and editing collections
- When collection.ID is empty: shows "Create Collection" form
- When collection.ID is set: shows "Edit Collection" form with pre-filled data
- Features:
* Name and description fields
* Icon picker with search input and emoji grid
(grid populated dynamically by JavaScript)
(supports typing emoji directly or searching by keywords)
* Color selection buttons (blue/red/yellow/green/purple)
* HTMX form submission (hx-post for create, hx-put for update)
- HX-Redirect to /collections after successful submission
2. RestoreSystemCollectionModal()
- Modal for restoring deleted system collections
- Dropdown with options: Continue Reading, Recently Added,
Recently Read, Not Started
- HTMX form submission to /api/dashboard/restore-system-collection
- HX-Redirect to /collections after restoration
Both modals:
- Use fixed inset-0 positioning with black/70 backdrop
- Inherit theme from parent page (no html/head/body tags)
- Include close button (✕) that calls closeCollectionModal()
- Follow existing card styling conventions
- Use CSS custom properties for theming (--bg-secondary, --text-primary, etc.)
Add three new frontend routes to support HTMX-powered modal dialogs:
1. GET /collections/create-modal
- Renders empty collection creation modal
- Uses CollectionModal template with empty CollectionData
2. GET /collections/:id/edit-modal
- Fetches collection by ID from database
- Pre-populates modal with existing collection data
- Returns 400 for invalid UUID, 404 if collection not found
3. GET /collections/restore-modal
- Renders system collection restoration modal
- Allows users to restore deleted system collections
Route registration order:
- /collections/:id/edit-modal must be registered before /collections/:id
to avoid path conflicts in Echo's router
These routes enable the collections page to load modals dynamically via
HTMX (hx-get) instead of embedding modal HTML in the base page.
Add form:"" tags to CreateCollectionRequest and UpdateCollectionRequest
structs to enable proper form data binding with Echo's c.Bind().
This change aligns with the pattern used in auth handlers where both
form:"" and json:"" tags are present, allowing the same request structs
to work with both JSON payloads (API) and form data (HTMX).
Changes:
- Add form:"name", form:"description", form:"color", form:"icon",
form:"auto_assign_rules", and form:"view_settings" tags to both
CreateCollectionRequest and UpdateCollectionRequest
Additionally, add HTMX redirect support to CreateCollection and
UpdateCollection handlers:
- Add HX-Redirect header for HTMX requests after successful create/update
- Add HTML redirect response to DeleteCollection for HTMX requests
(follows pattern from auth.go: inline script with window.location.href)
This ensures HTMX form submissions properly redirect to /collections
after successful operations, while maintaining API compatibility for
JSON requests.
- Update wood-light border from harsh black (#2a2a2a) to lighter warm brown (#8b5a2b) for better harmony with light background
- Update wood-dark border from #5c3317 to #7a5228 (slightly lighter medium brown) for improved visibility on dark backgrounds
- Update wood-mahogany border from #5c3317 to #8b3a3a (medium red-brown) to enhance mahogany's characteristic reddish tones
- Reduce background blend opacity from 60% to 40% to create more subtle text area background that complements new border colors
These changes improve visual consistency between border colors and their respective wood paneling backgrounds while maintaining good text contrast across all wood themes.
Update test files to work with recent backend refactoring changes.
Test changes in internal/services/dashboard_service_test.go:
- Fix method name casing for FilterHiddenCollections
- Change from filterHiddenCollections (lowercase 'f')
- Change to FilterHiddenCollections (uppercase 'F')
- Matches exported method signature in DashboardService
- Line 57: Update test call to use correct exported method
Test changes in internal/handlers/dashboard_test.go:
- Update getViewAllURL test to match simplified function signature
- Remove queryType parameter from test call
- Function now only takes collectionName parameter
- Aligns with refactoring to use /collections/{id} routing
- Line 178: Update test call to use new signature
These fixes ensure tests compile and run correctly after the
collection detail page refactoring where:
1. getViewAllURL() was simplified to return /collections/{id}
2. System collections now use the same routing as user collections
Add default library ID functionality to improve library targeting
during media scans.
Service changes in internal/services/media_scanner.go:
- Add defaultLibraryID field to MediaScanner struct
- Add SetLibraryID() method to set default library
- Modify processMediaFile() to use defaultLibraryID when set
- Prioritizes defaultLibraryID over folder-based library detection
- Provides explicit library targeting for scans
Service changes in internal/services/worker.go:
- Add libraryUUID conversion from string to pgtype.UUID
- Call scanner.SetLibraryID() before ScanFolders()
- Ensures scanner respects the job's library ID
These changes enable more precise library targeting during media scans,
allowing scans to be directed to specific libraries rather than relying
solely on folder-based detection.
Change library ordering in dropdown from DESC to ASC to display
libraries in creation order (oldest first).
Database changes in internal/database/queries/queries.sql:
- Modify GetUserLibraries query ORDER BY clause
- Change from ORDER BY l.created_at DESC to ASC
- Displays oldest libraries first in dropdown
This provides a more intuitive ordering where users see their
first-created libraries at the top of the list.
Fix multiple issues with wood paneling background image display
affecting overscroll area and page-specific rendering.
CSS changes in web/static/input.css:
- Add background-attachment: fixed to all wood paneling classes
- Prevents wood paneling from moving during page scroll
- Ensures wood paneling extends into overscroll area
- Applied to bg-wood-dark, bg-wood-light, bg-wood-mahogany
- Fix body and container selectors for wood paneling
- Ensure proper selector targeting for wood paneling application
- Use background-position: center for better alignment
- Use background-size: cover for full coverage
TypeScript changes in web/src/woodPanelingInit.ts:
- Add page detection to prevent wood paneling on collections page
- Check if #collections-container exists in DOM
- Only apply wood paneling on dashboard, not collections page
- Prevents ID collision between dashboard and collections containers
Template changes in templates/header.templ:
- No functional changes, only reformatting
These fixes ensure that:
1. Wood paneling displays consistently across the entire viewport
2. Wood paneling extends into the overscroll area when scrolling past content
3. Wood paneling is properly aligned and centered
4. Wood paneling doesn't interfere with collections page rendering
5. Both dashboard and collections pages can coexist without visual conflicts

- Use applyPreferencesToModal() to update slider and toggles
- Ensure modal reflects current library's settings
Backend changes in internal/router/dashboard.go:
- Update GetDashboardPreferences to use library_id query parameter
- Matches frontend API call parameter naming
Template changes in templates/dashboard.templ:
- Remove duplicate renderDashboardCollections() inline script
- Functionality now handled by dashboard.ts
These fixes ensure that:
1. Dashboard settings work correctly per library
2. Slider reflects and updates the correct library's item limit
3. Toggles show accurate visibility state for each library
4. Library switches provide smooth visual feedback
5. Errors are properly surfaced to users via toast messages
Add comprehensive collection detail page that works for both system collections
(continue-reading, recently-added, not-started) and user collections.
Backend changes:
- Add new /collections/:id route in internal/router/frontend.go
- Fetches collection using GetCollection with UUID parameter
- Determines collection type from QueryType field
- Resolves library_id for system collections
- Converts database.MediaItems to handlers.BookInfo for display
- Renders CollectionDetail template with collection and books data
- Update SectionData struct in internal/handlers/collections.go
- Add CollectionID string field for view all links
- Update BuildSections() in internal/handlers/dashboard.go
- Pass CollectionID to SectionData for proper link generation
- Simplify getViewAllURL() in internal/handlers/dashboard.go

- Works uniformly for both system and user collections
Frontend changes:
- Fix CollectionDetail template in templates/collections.templ
- Fix broken div nesting causing compilation error
- Add null check for CoverImagePath to prevent broken images
- Update aspect ratio to modern aspect-[3/4] syntax
- Use responsive widths (w-16 sm:w-20) for mobile/desktop
- Improve card layout with horizontal flex structure
- Add placeholder image fallback for books without covers
- Remove erroneous renderBooks() function call
This change aligns with the backend update where system collections are
now pre-made user collections in the database with query_type fields.
All collections can now use the same CollectionDetail template for a
consistent viewing experience.
- Update validation from minutes (15-1440) to seconds (1-3600)
- Clarify behavior: real-time file watching with polling fallback
- Remove scheduler references from development docs
- Update migration notes for the new implementation
