foliate-js has no npm release and no build step; upstream recommends a git submodule. Copy it instead: this repo has no submodules and already vendors pdf.js the same way under static/pdfjs, and a submodule would pull in 231 files / 13 MB of which 191 files / 12 MB is a bundled pdf.js build that Chitai does not use. Only the import closure reachable from view.js is vendored — 15 files, 584K. pdf.js is replaced by a stub that throws: view.js reaches it through a static-string dynamic import inside makeBook, which Rollup resolves at build time even though Chitai serves PDFs from static/pdfjs/web/viewer.html, and upstream's version opens with a bare `import '@pdfjs/pdf.min.mjs'` that does not resolve here. scripts/vendor-foliate.sh pins the commit and makes the next update a one-line change. fixed-layout.js needs construct-style-sheets-polyfill, so add it.
Vendored foliate-js
Do not edit these files. They are copied verbatim from upstream by
frontend/scripts/vendor-foliate.sh; local changes are lost on the next run.
| Upstream | https://github.com/readest/foliate-js (Readest's fork of johnfactotum/foliate-js) |

Readest's fork is used rather than upstream for its paginator work: touch/swipe
turn handling, fixed-layout spread centring, and a malformed-XHTML fallback in
loadDocument.
What is here
Only the import closure reachable from view.js. Not vendored, because nothing
reaches them: dict.js, opds.js, footnotes.js, quote-image.js,
uri-template.js, reader.js (upstream's demo), and the build configs.
pdf.js is ours, not upstream's
pdf.js in this directory is a stub that throws. Upstream's version imports
@pdfjs/pdf.min.mjs — a bare specifier backed by a 12 MB vendored pdf.js build —
and view.js reaches it through await import('./pdf.js'), which Rollup resolves
at build time even though Chitai never takes that path. Chitai serves PDFs from
static/pdfjs/web/viewer.html instead.
To enable foliate's PDF backend, add pdf.js and vendor/pdfjs/ to the file list
in the vendor script and drop the stub.
Updating
Bump FOLIATE_SHA in frontend/scripts/vendor-foliate.sh, re-run it, review the
diff, and smoke-test the reader — paginator.js is ~3800 lines of gesture and
animation code and this fork is pushed to frequently.
