PDFs failed to open with error:
Invalid factory url: "http://localhost:8765/static/undefined"
Root cause: foliate-js's pdfjsPath() uses new URL(dynamicPath, import.meta.url)
to resolve runtime asset paths (standard_fonts/, cmaps/). Vite transforms this
pattern into a static asset map lookup at build time, but can only resolve
known static file paths — not dynamically-constructed directory paths. The
lookup returns undefined, producing a broken URL.
Fix (two parts):
1. foliate-js fork (commit d164d6f): Export an overridable config.pdfjsPath
function. Module-level code (worker, CSS) continues using import.meta.url
directly (works fine with Vite for static filenames). The makePDF function
uses config.pdfjsPath for runtime paths, allowing consumers to override it.
2. Bookhoard changes:
- Update foliate-js dependency to d164d6f
- Override config.pdfjsPath in reader.ts to resolve to /static/vendor/pdfjs/
- Add Vite plugin (pdfjsAssets) that copies standard_fonts/ and cmaps/ from
node_modules to the build output during vite build (the standard approach
used by react-pdf and other pdfjs-dist consumers)
- Remove manual cp commands from build:ts scripts
