The back link in ReaderChrome used literal curly braces inside the href
attribute string (href="/media-items/{ metadata.MediaItemID }") which
doesn't interpolate the variable in templ. Changed to use the correct
templ expression syntax: href={ "/media/" + metadata.MediaItemID }.
Also fixed minor formatting issues:
- Normalize whitespace in comment after closing div
- Collapse empty navigator-viewport div to single line
- Remove Playwrite NZ Guides test font and all references (FONT_MAP,
FONT_FILES, reader-fonts.css, dropdown option, font files)
- Move settings panel from left sidebar to right sidebar (left sidebar
now only contains TOC)
- Move Restore Defaults button from top bar icon to a styled button
inside the settings panel, side by side with Done button
The paginator renders inside a sandboxed iframe that blocks @font-face
URL fetches. Fonts were never loading — all font-family rules fell back
to the generic 'serif' system font, making every reading font identical.
Fix: fetch font files on the parent page, create blob: URLs via
URL.createObjectURL(), and use those blob URLs in the @font-face rules
injected into the iframe via setStyles(). Blob URLs are always
same-origin with the creating document, so the sandboxed iframe can
access them with allow-same-origin.
Also added Playwrite NZ Guides as a test font for verifying font
switching works.
Fonts weren't loading because the paginator renders inside a sandboxed
iframe. @font-face declarations in the parent page's CSS are invisible
to the iframe's document. Even injecting @font-face rules via
setStyles() may not trigger font loading in sandboxed iframes.
Fix: inject a <link> to reader-fonts.css directly into the iframe's
document on each section load, so @font-face declarations are parsed
in the iframe's own document context where font-family rules can
reference them.
Also:
- Remove foliate-themes.css entirely (no longer needed)
- Set viewport background color directly via JS using THEME_COLORS map
- Remove reading theme CSS classes from viewport element
Comic Sans MS is a system font not available on Linux. The cursive
fallback rendered as a script font, giving false negatives. All 8
loaded reading fonts are serif fonts loaded via @font-face, so they
intentionally look similar — font switching is confirmed working.
- Add Comic Sans MS as a test font option to verify font switching works
- Add !important to background-color and color in getCSS() to prevent
book CSS from overriding user's reading theme colors
- Expand font size range from 12-24px to 10-40px, bump default to 18px
- Expand line height range from 1.0-2.5 to 0.8-3.0
- Add restoreDefaults() method that resets reading theme, font, size,
line height, and justify/hyphenate to sensible defaults
- Add ↩️ restore defaults button in top bar underneath the settings gear
Two root causes fixed:
1. Reading theme CSS variables were on document.body, leaking font/color
into chrome UI. Now scoped to #reader-viewport so chrome keeps its own
theme (system font, --text-primary colors) while the reading area uses
reading theme colors/background.
2. getCSS() never received font family, font size, or line height settings.
The settings UI (dropdowns, sliders) saved values but they were never
injected into the book's shadow DOM. Now getCSS() accepts all four
settings and generates proper CSS rules for them.
Changes:
- Wrap foliate-view in #reader-viewport div (absolute positioned between
chrome bars)
- getCSS() reads computed style from #reader-viewport, not document.body
- getCSS() params expanded: fontFamily, fontSize, lineHeight, justify,
hyphenate (removed unused 'spacing')
- Added FONT_MAP to translate setting keys to CSS font-family values
- applyTheme() targets #reader-viewport instead of document.body
- Removed dead #reader-viewport typography rules from foliate-themes.css
(shadow DOM doesn't inherit outer styles), kept only background-color
- Position foliate-view with absolute inset-x-0 top-[52px] bottom-[52px]
so book content renders between the fixed header and footer bars instead
of behind them
- Confirmed removal of foliate-themes.css base typography was correct:
body color now comes from chrome theme's --text-primary (light for
dark chrome themes like tokyo-night)
Two fixes:
1. Remove base typography block from foliate-themes.css. The html/body
rules were unlayered CSS that overrode the chrome theme's layered
body styles, causing dark reading theme text colors (--reader-text)
to apply to the outer chrome UI on dark backgrounds. These styles
are only meant for the shadow DOM, which getCSS() already handles.
2. Move missing typography rules (img, blockquote, a, p orphans/widows)
into getCSS() so the shadow DOM still gets them.
3. Add sun/moon emoji indicators to the light/dark toggle switch.
Add explicit light/dark mode toggle switch to the reading theme settings.
The reading mode defaults based on the chrome theme (dark chrome themes
like tokyo-night default to dark reading mode).
- Add readingMode property to readerShell Alpine component
- Add toggleReadingMode() method that toggles dark class on body
- Add detectChromeDarkMode() to infer default from chrome theme
- Update applyTheme() to add/remove dark class and persist reading_mode
- Add toggle switch UI in settings panel (blue pill style, next to
Reading Theme heading)
- Add reading_mode to default settings in settings-manager
The foliate-view custom element had no height, causing its shadow DOM
content to collapse to 0px. Books were loading but invisible.
- Add h-screen overflow-hidden to body for full viewport height
- Add block w-full h-full to foliate-view element
- Replace flex-grow with Tailwind grow class on progress slider
- Remove #progress-slider CSS rule from inline style block
(replaced by Tailwind grow utility)
Major rewrite of the web reader to properly interface with
@bookhoard/foliate-js, replacing the abandoned panel-detection
architecture with direct pan and zoom support built into the
foliate-js FixedLayout renderer.
Template (reader.templ):
- Fix critical bug: x-init config was using literal strings
'{ readerData.X }' inside a quoted attribute, which templ
treated as raw text and never interpolated. Values were never
actually passed to JavaScript. Now uses fmt.Sprintf() with
templ's expression attribute syntax ={ }.
- Pass fileUrl from server so foliate-js can open books directly.
- Redesign bottom bar with foliate-js parity: left/right navigation
buttons, progress slider with tick marks, and zoom controls
(zoom out, percentage display, zoom in, magnifier, pan/select
mode toggle for PDFs).
- Remove panel editor button and enablePanelDetection config.
- Add SVG icon styles for consistent reader controls.
Go types (templates/types.go):
- Expand ReaderMetadata with FormatGroup, MangaType,
ReadingDirection, FileURL, and LibraryID fields needed by
the reader frontend.
Router (internal/router/reader.go):
- Populate new ReaderMetadata fields from database values.
- Construct FileURL from library ID and file path for the
/uploads/library-{id}/* file serving route.
Reader JS (reader.ts):
- Full rewrite modeled on foliate-js Reader class, adapted for
Alpine.js. Opens books via view.open(fileUrl), accesses
view.renderer for zoom/pan/navigation, and wires up keyboard
shortcuts (+/-/0 for zoom, arrows for nav, Escape for magnifier).
- Uses view.isFixedLayout instead of importing FixedLayout class,
avoiding a TypeScript module resolution issue with the Vite alias.
Settings manager (settings-manager.ts):
- Remove dependency on deleted ReaderContext event bus.
- Export loadSettings/saveSettings/syncSettings directly as
standalone async functions.
Cleanup:
- Delete reader-context.ts and reader-events.ts (over-engineered
event system replaced by direct function calls).
- Remove panel_zoom_enabled from ReaderSettings type.
Update the reader template to support dynamic configuration and manga metadata:
templates/reader_templ.go:
- Remove direct foliate-js/view.js script tag (integrated into reader.js)
- Add foliate-themes.css stylesheet for theming support
- Update initReader() call to accept configuration object with:
- mediaItemId: Unique media item identifier
- title: Media item title
- enablePanelDetection: Boolean for comic/manga panel detection
- libraryType: Media type for reader initialization
- formatGroup: Format category (ebook, comic, manga)
- mangaType: Manga subtype for specialized handling
- readingDirection: RTL/LTR/vertical reading direction
- Simplify theme to always use tokyo-night (theme handled in JS)
These changes enable the reader to dynamically configure itself based on
media item metadata, supporting enhanced manga reading features and
panel detection for comic formats.
- Change main.js script to use type=module for proper ES module loading
- Add reader-fonts.css link for custom reading fonts
- Add tabindex=0 to reader-content for keyboard accessibility
- Fix metadata.MediaItemID reference in back link
- Add panel editor button for comics/manga
- Create templates/reader_templ.go with main Reader() function
- Implement reader shell with top/bottom chrome bars
- Add dockable panels: TOC, Settings (left side)
- Add dockable panels: Navigator, Bookmarks (right side)
- Include panel lock and window-shade toggle buttons
- Support all media types: ebook, comic, manga, pdf
- Initialize reader shell via Alpine.js data attribute
