Consolidate the frontend toolchain onto babel, and ship one bundle (#2178)
Four upgrades that were finished but never merged, the compiler collapse
they enable, and the dependency sweep that follows. Direct
devDependencies go from 78 to 60 and dependencies from 10 to 9.
Three were doing the same job: `ts-loader` stripped types in webpack,
`babel-loader` did everything else, and `@swc/jest` repeated both for the
tests with its own copy of the JSX settings. Babel is the one that
survives, because the `data-testid` stripper has no equivalent elsewhere.
`ts-loader` ran `transpileOnly: true`, so it only stripped types, which
`@babel/preset-typescript` does; `fork-ts-checker-webpack-plugin` was
already what type-checks. Jest runs `babel-jest` against the same
`.babelrc.js` the bundle uses, passed as `configFile` because a
file-relative babel config does not reach the `node_modules` packages in
`transformIgnorePatterns`, and `jest.config.mjs` is plain ESM because a
`.ts` config is compiled against `tsconfig.json`, whose
`verbatimModuleSyntax` rejects ESM syntax in a file the package has not
declared as a module.
That removes `ts-loader`, `@swc/jest` and `@swc/core`. The last was
pinned to 1.2.205 from 2022 with no way forward, because newer builds
emit non-configurable exports and break `jest.spyOn` across 13 suites.
Babel compiles a file at a time with no type information, so it cannot
tell a type-only import from a real one and keeps the module. One line,
`import { boundActions } from './connected-comment'`, pulled the whole
redux store into `last-comments.mjs` and doubled it. `verbatimModuleSyntax`
and `@typescript-eslint/consistent-type-imports` mark them properly; the
statement has to be a separate `import type`, since verbatim semantics
keep an inline `import { type X }` and load the module anyway.
The legacy and modern compilations produced the same bytes. Both read the
same browserslist query, `defaults, not IE 11, not samsung 12` resolves to
chrome 109 and up, and nothing in the source needs transforming for that
set, so 28 of the 29 output pairs were byte-identical.
That made the module/nomodule switch worse than redundant: it served the
`.js` file to browsers with no ES module support, and those files carried
`??`, `?.` and class fields, so the fallback handed its own audience a
syntax error. There is now one bundle, always loaded as a module, in the
five templates and in the seven `site/` documents integrators copy from.
A production build emits 29 files rather than 58, in about 3 seconds
rather than 17. Two of those documents did not work at all beforehand:
the SPA snippet could not parse, and the subdomain example had an
unterminated string.
`@babel/core` 8 declares `^22.18 || >=24.11` and `size-limit` 13 declares
`^22.18 || ^24 || >=26`, so 20 was below the floor of two things installed
here; pnpm only warns, which is why every build passed. All seven places
the frontend pins it move together. `site/` is untouched: it builds with
yarn and eleventy and installs neither.
`eslint --print-config` before and after gives 173 active rules on an
application file against 172, and 172 on a spec file and a plain JS file
against 171. What is gone is three `flowtype` rules with no Flow here,
`no-new-object` and `no-new-symbol` whose upstream replacements are on,
`react/forbid-foreign-prop-types` with no propTypes anywhere, and, on TS
only, `no-useless-constructor`, whose typescript-eslint version is on at
error. `@babel/core` is pinned to 8 across the workspace because
`@jest/transform` and `istanbul-lib-instrument` depend on 7 outright; a
second scoped override holds `eslint-config-preact` on 7, since its
`@babel/eslint-parser` loads babel 7 syntax plugins.
`fast-async` rewrote every async function into nodent promise chains,
calls babel's `transform` synchronously, which babel 8 removed, and every
browser in the target list runs async natively. `prefresh` blew its stack
on `createContext` under babel 8 with no newer release to move to, which
compiled `intl.tsx` and `store/context.tsx` into throwing stubs, so
`pnpm dev:app` could not run the widget at all. `core-js` is not injected
now that `useBuiltIns` is gone, `postcss-custom-properties` was reached
directly although nothing declared it and resolved only through pnpm's
private hoist directory, and `cssnano` ran in both postcss chains although
`CssMinimizerPlugin` already uses it.
`pnpm lint`, `pnpm test` and `pnpm build` now work from `frontend/` as
`CLAUDE.md` and the contributing guide have always said they do; the
workspace root defined none of them.

Move the site from eleventy to hugo (#2179)
* Move the site from eleventy to hugo The site is built by a single static binary. No node, no package manager, no lockfile, and the toolchain it needed is gone: eleventy, tailwind, postcss, markdown-it and its three plugins, date-fns, prism, npm-run-all, cross-env and html-minifier-terser. Hugo covers most of that itself. Chroma replaces prism, goldmark replaces markdown-it, `--minify` replaces html-minifier-terser, and fingerprinted asset URLs replace the cache-busting `version` shortcode that stamped `Date.now()` into every stylesheet link. `assets/styles.css` is hand-written, since tailwind was the only reason left to keep a package manager. The palette and the light and dark values are custom properties at the top of the file; the minified stylesheet is 15 kB against tailwind's 46 kB, and the whole build 1.0 MB against 1.2 MB. It was matched to the old one by comparing computed styles rather than by eye, which is how the heading weights and line heights, the list marker colour, and the home page heading and sign-off were caught: the last of those had been carried by tailwind utilities written into the markup. The `::: note` container becomes a `note` shortcode taking the emoji to show. Its closer needs a blank line after it, because a shortcode is not a block rule the way `markdown-it-container` was, and without one goldmark keeps the callout inside the open paragraph. The `overflow-x` wrapper around tables and the heading anchors are goldmark render hooks. Syntax guessing is off. Chroma detected a systemd unit file as gdscript and a chat transcript as mysql, and colouring a snippet as the wrong language is worse than not colouring it. The two chroma themes are scoped to opposite sides of the theme switch rather than layered, because they do not declare the same properties on the same tokens: github gives Error a background github-dark never overrides, and styles Punctuation where github-dark leaves it alone. Layered, either leaves a light value applying on a dark page. `[frontmatter] lastmod` resolves through git, then front matter, then file modification time. Without that chain `.Lastmod` falls back to `.Date`, which is zero when a page carries no date, and every page reads `Jan 01, 0001`. `enableGitInfo` is off because the image build context is `site/` alone, where hugo fails hard rather than degrading; `HUGO_ENABLEGITINFO=true` gives real per-page commit dates locally. Three fixes fall out of the move rather than being sought: - `/docs/` redirected nowhere. The stub was a markdown file whose permalink was a template expression while `markdownTemplateEngine` was false, so it never rendered and the URL 404'd. It is an alias now - `/docs/contributing/` pointed at `/docs/contributing/development/`, which has never existed. It points at the backend page - the 404 page was built to `/404/` and nothing served it. Hugo writes it to `/404.html` and reproxy is told to use it The mobile documentation menu is a checkbox and label. `visibility: hidden` on the checkbox, which is what the old `invisible` utility set, takes it out of the tab order, and a label is not focusable on its own, so the menu could not be opened from the keyboard at all. The checkbox is clipped rather than hidden, and its label shows a focus ring. Content is unchanged. Every code block on every page is byte-identical to the eleventy output; the only prose difference is that two example values, `mysite.com` and a quoted `https://demo.remark42.com`, are no longer turned into links, goldmark's linkify being narrower than markdown-it's. `backend/README.md` and `frontend/apps/remark42/README.md` are symlinks into the docs tree and follow it to `site/content/`, as does the path `release.yml` watches. `frontend/CLAUDE.md` described the site as a node and yarn project in four places. * Keep the heading anchors markdown-it generated Goldmark strips punctuation markdown-it kept, so 22 headings holding a dot, slash, apostrophe, question mark, bracket or em dash would take a new id and any link into one from outside the repository would stop resolving. Those headings carry their previous id as well, as an empty target emitted ahead of the heading by the render hook, from a map of content path to old anchor in `data/anchor_aliases.json`. The map was built by matching heading text between the two builds rather than by position, so it survives a heading being added or moved. The hook rather than markdown, because goldmark's `{#id}` attribute syntax cannot express these: it accepts dots, apostrophes and em dashes but treats a slash, a question mark, a bracket or a percent sign as heading text, which is 11 of the 22. The ids are stored percent-decoded, since a browser decodes a fragment before matching, so `#children%E2%80%99s-privacy` finds `children’s-privacy`. Verified by navigating to the awkward ones against the built image and measuring where the page settles: each lands 112px down, which is the header offset the target carries. Three pages carried no title, so the docs template rendered an empty `<h1>` above the heading their markdown already had. They take their titles from that heading text, so neither the wording nor its anchor changes, and the template's `<h1>` carries an id. One in-page link pointed at an anchor goldmark no longer generates. The heading render hook emits no permalink anchor. The one it replaced was an empty `<a href>` with `pointer-events: none`, so it could not be clicked, and its only job was a `::before` spacer that `scroll-margin-top` on the heading already does. Being an `<a href>` it stayed in the tab order, so every heading was an unexplained keyboard stop: eight on the installation page alone. Fragment navigation still lands 112px down, clear of the fixed header. * Harden the site image build and its CI The architecture guard could not fire. `${TARGETARCH:-amd64}` defaulted before the `unsupported arch` branch was reachable, so a build without buildkit put an amd64 hugo inside an aarch64 image and ran only because Docker Desktop emulates it. Reproduced with `--build-arg TARGETARCH=`: `/etc/apk/arch` reported aarch64 and `hugo version` linux/amd64. An empty value is an error now. `Dockerfile.dev` had the same defect and no smoke step to catch it, so it would have failed at `compose up`. The hugo tarball is verified against the release's own `checksums.txt`, and the match is asserted present before it is used: piping grep straight into `sha256sum -c` left the guarantee resting on what the checker does with empty input. Busybox exits 1 there, so it did fail closed, but nothing in the line said so. Verified against a checksums file that does not list the tarball: the build stops before the install. Hugo exits 0 on an empty content tree and emits a two-page shell, which would have been copied, pushed and deployed. The build asserts the home page and a docs page exist. `site/**` pull requests were never built. The only building job is gated on `github.ref == 'refs/heads/master'`, so on a pull request every job skipped and rendered in the checks list the same way a pass does, and the image was first built on the run that also deploys it. A `validate` job builds it with `push: false`, needing no secrets so it works on a fork. `.github/dependabot.yml` watched `/site` for npm packages that are gone. That entry is a docker one, which tracks the alpine base. It does not track the hugo pin and cannot: the docker ecosystem reads `FROM` references, and `ARG HUGO_VERSION` is a bare string in a download URL, so that one is a manual bump and `site/README.md` says so. `Dockerfile.dev` carries a `COPY`, so the dev image works without the compose bind mount, and compose runs as the invoking user rather than root, which on linux left root-owned `public/` and `resources/` in the checkout. Recorded in the backlog: `master` has `required_status_checks` off with an empty check list, so the new job surfaces a red X and does not block a merge. That is a settings decision rather than a code fix. |
