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.
* Serve the build-independent web assets from the backend
`privacy.html`, `markdown-help.html` and the `400x400.jpeg` it embeds carry
no template variable, link no script or stylesheet, and are imported by
nothing in the widget. They now live in `backend/app/webassets/assets`,
embedded there, and are served under `/web` alongside the frontend build.
`/web` reads the frontend build first and falls back to them, which is what
lets an operator replace one by dropping a file into `--web-root`. That is
what `privacy.html` needs: it describes remark42.com, while the
authorization guide tells operators to hand its URL to Google and Facebook
as their own application's privacy policy.
Only a missing file falls through. An unreadable file in the web root keeps
reporting as unreadable rather than being silently replaced by the embedded
copy, and a name the filesystem rejects reports as missing rather than as a
server error, both matching what `http.Dir` did.
The dev server serves the same directory, so the Markdown help link in the
comment form resolves on the dev port as well as in production.
The two pages are served as they are written. `markdown-help.html` was
minified before, and its formatted inline stylesheet is most of its 8.5 kB;
that is 2.4 kB more over the wire, behind the hour-long cache header the
file server already sets.
Drops `copy-webpack-plugin`, which had no other pattern, and the stylelint
entries that only ever matched these files.
* Make pnpm dev:app start again
The dev server has been failing to start on two counts, so the flow the
contributing guide documents does not run at all.
`webpack-cli` 4 drives `webpack-dev-server` 5 through the argument order
of an older major, handing it the compiler where it expects the options
object. It rejects that against its schema and exits, complaining about an
unknown `_assetEmittingPreviousFiles` property, which is a field of the
compiler. `webpack-cli` 7 is the release that declares
`webpack-dev-server` 5 as a peer.
Past that, `http-proxy-middleware` resolves to 4.1.1, which no longer
accepts the two-argument call `webpack-dev-server` makes, so the `/api`
and `/auth` proxies throw on startup. It is pulled in by the security
override for CVE-2025-32996, the only override in the file with no upper
bound: `>=2.0.10` matches every later major. Bounding it to the 2.x line
keeps the fix and the API `webpack-dev-server` calls.
With both in place `pnpm dev:app` serves the widget and the pages under
`/web` on port 9000.
Second and final step of #2166. `react-intl` is replaced by
`app/common/intl.tsx`, a small i18n binding over Preact context, and with
`react-redux` already gone nothing holds the React compatibility alias.
React is now absent from the lockfile, the installed tree, the config and
the bundles: `react`, `react-dom`, `react-intl`, `@types/react`,
`@preact/compat`, `use-sync-external-store` and `intl-messageformat` are
all gone, along with the `paths` entries in `tsconfig.json` and three
babel-loader excludes. Runtime dependencies go from 15 to 10.
`preact/compat` goes too, which matters more than its 3.8 kB. Importing
it anywhere installs hooks on preact's shared `options` that remap
`onFocus`/`onBlur` to `focusin`/`focusout` for every element and make
`@testing-library/preact` rewrite `change` to `input`, the two bugs
behind #2166, still live until now. `Button` was wrapped in `forwardRef`
with no caller passing one, and `TextareaAutosize` now takes its ref as
an ordinary prop. The workaround in `sort-picker.spec.tsx` is gone with
them, since `fireEvent.change` reaches a `<select>` again.
Gzipped, against master: `remark.mjs` 76.17 kB to 56.47, `last-comments.mjs`
37.97 to 18.26, `deleteme.mjs` 14.51 to 8.42. The limits move with them and
keep more relative headroom than master shipped.
### The binding
`IntlProvider`, `useIntl`, `createIntl`, `defineMessages`,
`FormattedMessage` and `IntlShape`. 32 files change only their import.
The export names copy react-intl's deliberately: `formatjs extract` finds
messages by recognising `defineMessages`, `FormattedMessage` and
`intl.formatMessage` in the AST rather than by import source, so renaming
one silently empties the catalogue. `frontend/CLAUDE.md` records that,
along with the destructive part: `translation:generate` would then strip
the unextracted keys from all 24 catalogues and the check would pass.
A message the binding cannot parse falls back to the message in the
source: a broken, unhandled or nested tag, a brace that is not a
well-formed placeholder, and a placeholder naming a value the caller did
not supply. `mk.json` and `th.json` carried broken markup and rendered in
English; both are repaired, so a catalogue sweep over every locale can now
require well-formed markup with no exceptions listed.
`translation:check` gained the validation that would have caught them when
they were proposed: a translation's tags have to be well-formed pairs of the
names the English string uses, with no attributes, and its placeholders have
to be ones the English string provides. Leaving a tag or a placeholder out
stays allowed. Run against master's catalogues it reports both.
### enzyme
`@types/enzyme` was the last thing pulling `@types/react`, so React could
not leave while enzyme stayed. Its three test files move to
`@testing-library/preact`, which now has no rival: `@testing-library/preact-hooks`
had one import left and its own unmet peer warning. `intersection-observer`
was a runtime dependency nothing imported, and the `cheerio` override lost
its last dependent with enzyme.
Enzyme's `.find(X).prop()` threw unless exactly one node matched, so the
converted tests assert node counts explicitly to keep that.
### Verified
All 181 message ids formatted across all 24 catalogues through both real
react-intl and this binding: 4344 comparisons, no differences. From a wiped
`node_modules`: `pnpm install --frozen-lockfile`, `pnpm lint`,
`pnpm type-check`, `pnpm test` (392 tests, 42 suites), `pnpm build`,
`pnpm size-check`, `pnpm translation-check`.
* Update preact to 10.29.8
Also moves TypeScript to 5.9, which preact 10.29 typings require, and the
compat and testing library pins that go with it. Type checking resolves
JSX from preact via the automatic runtime; the bundle keeps the classic
transform so babel still strips test ids.
* Move babel to the automatic JSX runtime and refresh frontend notes
Leaving babel on the classic h pragma while tsconfig used the automatic
runtime meant a tsx file without an h import would type-check and lint
clean, then throw at runtime, since eslint-config-preact disables
react/react-in-jsx-scope and no-undef is off.
* Address review findings on the preact upgrade
Forward the textarea ref with useImperativeHandle so it clears on unmount
and lands during commit rather than after paint. Pair typescript-eslint
with the TypeScript it now has to parse. Use the preact namespace types
rather than the deprecated JSX aliases, and drop the redundant type
re-declarations the element-specific interfaces already provide.
* Drive the focus tests through real DOM focus and blur
Dispatching a synthetic focusin hard-coded preact/compat's internal
alias for onFocus. Calling focus() and blur() exercises the sequence a
browser produces and stays correct if that mapping changes.
* Raise the two bundle limits the preact upgrade pushes past
CI measures remark.mjs at 78024 bytes against a limit size-limit reads as
78000, so it failed by 24. last-comments.mjs had 36 bytes of headroom and
would have tripped on the next change.
* Regenerate the lockfile after the rebase
The rebase resolution left it missing the @typescript-eslint entries, so
every CI job failed at pnpm install --frozen-lockfile.
* Drop the @remark42/api package
It cannot authenticate anyone: clients/auth.ts exposes only anonymous,
email and telegram, with no OAuth method, and the fetcher never sets
credentials so its cookie auth cannot work cross-origin. Nothing in the
repo consumes it, no third-party consumer exists, and npm has served an
alpha from July 2022 that CI never publishes.
* Drop the removed workflow from the pnpm pinning checklist
frontend/CLAUDE.md still counted ci-frontend-api.yml among the places the
pnpm version is pinned, and stated a fixed total that no longer holds.
All 23 open Dependabot alerts against frontend/pnpm-lock.yaml resolve to
packages whose override floor sat below the patched release. Every floor
now carries an explicit upper bound, as an open-ended floor lets pnpm
resolve across a major version.
pnpm 8.15.9 -> 10.10.0 (packageManager + lockfile regenerated to v9). Frontend
CI (ci-frontend.yml, ci-frontend-api.yml, release.yml) and the production
Dockerfile bumped from node 16 + pnpm 8 to node 20 + pnpm 10 (pnpm 10 requires
node 18+). pnpm audit: no known vulnerabilities (was 63 alerts).
packages/api: bumped to latest including the major test stack - vitest 4, jsdom
29, @vitest/coverage-v8 4, @typescript-eslint 8.62, typescript 5.9, prettier
3.9, @types/node 26, and msw 1 -> 2. Migrated tests/test-utils.ts to the msw 2
http/HttpResponse API (capturing a compatible request shape) and made test base
URLs absolute so node 20's native fetch is intercepted; added the jsdom base
URL. type-check:api, lint:api and coverage:api (45 tests) all pass.
apps/remark42: safe in-major bumps (webpack 5.108, postcss, mini-css-extract,
html-webpack-plugin, ts-loader, webpack-dev-server 5.2.5, core-js, clsx 2,
lodash-es 4.18, dotenv 17, @types/*). Transitive vulns patched via
pnpm.overrides. type-check, lint, build, jest coverage (299 tests) and
translations all pass.
pnpm 10's stricter layout required a few pins to keep the app's preact-compat
setup compiling: preact 10.6.2 (override), react-intl 6.0.5 and
@testing-library/preact 3.2.2 (newer types break the build), tsconfig paths for
preact, @types/minimatch 5.1.2 (6.x is an empty stub) and cheerio 1.0.0-rc.12
(1.2 is ESM and breaks jest 28). Held: react/react-dom (preact compat alias),
babel 7, eslint 8, stylelint 14, jest 28, typescript 4.7 (app),
redux/react-redux - majors that change the bundle or need a config migration.
Build output verified against a clean master build: apps/remark42 output is
functionally identical (the only diffs are webpack module-id numbering and
css-module class tokens from the webpack/css-loader bump; all HTML, CSS values
and translations byte-identical).
