* fix(i18n): translate hard-coded labels, snackbars and missing keys Catalog screens, snackbars and external player messages showed English in every locale, and seven keys used in code were missing from en.json, so ngx-translate rendered them raw. - Catalog: "All items", item and channel counts, channel sort menus and tooltips, unnamed-category and empty-category labels, LIVE/PAUSED badges and the Xtream global search summary are translated. The Xtream and Stalker stores no longer bake an English name into the every-item sentinel; the facades return a null title and the view translates it. - Snackbars: Xtream/Stalker request failures, the 413 upload error, backup export/import results and the category visibility failure use keys; every "Close" action uses CLOSE. - External player: the main process sends an error code instead of an English sentence (player-error event, session errorCode, and a tag in rejected launch errors); the renderer, dock and VOD primary button translate it. The external player info dialog is translated. - Adds the seven missing keys and 43 new ones, translated in all 18 locales; seven legitimately identical values are baselined. - tools/i18n/check-usage.mjs fails on keys used in code but missing from en.json; it runs in i18n:check (and so in CI through i18n:validate). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(i18n): translate catalog counts in the template and skip inline template comments - The category subtitle hands a key to the translate pipe instead of caching translate.instant(), so a cold start re-renders it once the language file loads. - The Xtream live root count uses the singular/plural item keys, so one result no longer reads "1 channels". - check-usage.mjs strips HTML comments inside inline templates of TypeScript files, so a commented-out key no longer fails the check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(i18n): check keys in parenthesised translate pipe operands `(expanded() ? 'SHOW_LESS' : 'SHOW_MORE') | translate` yields keys that neither precede the pipe directly nor contain a dot, so the usage check missed them. It now reads the ternary and fallback branches of a parenthesised operand; a literal compared in the condition is not read as a key. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(e2e): expect the translated external player failure in the dock A launch failure without an error code now shows the translated generic status in the playback dock, with the raw main-process detail as its tooltip. The ClearKey DASH flow asserted the raw English text. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(playback): keep the IPC error tag out of the stored session detail A tagged launch failure reached ExternalPlayerSession.error unchanged, so the dock tooltip showed "[iptvnator:external-player:start-failed]". The registry now strips the tag when it stores the detail; the rejected IPC error keeps it for the renderer to read the code. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(web): expect translated portal request failure toasts #1861's new resolved-failure specs asserted the English toast text; the toasts now go through PORTALS.REQUEST_ERRORS keys, so the specs check the key and its message/status params. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(i18n): read only returned branches of a grouped translate operand A literal at the start of a condition, as in `('ERROR' === status() ? 'CLOSE' : 'CLOSE') | translate`, was taken for a translation key, so a valid template could fail the usage check. A grouped literal now counts only when it ends its operand (end of group, `:`, `||` or `??`). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(i18n): translate the remaining hard-coded labels Follow-up to the UI-26 pass. The remaining English UI literals now come from translation keys, translated in all 18 locales: - Windows/Linux window controls, playlist switcher title and actions menu, the portal status tooltip, dashboard carousel roles and rail scroll buttons, the search placeholder, the card remove tooltip, the EPG offset unit, the REC chip, the Stalker EPG source label and the export file type. - Embedded MPV failures raised in the renderer and the release-notes dialog without a bridge. Settings never showed its English reasons, so they are dropped. - Unnamed Stalker episodes: data access leaves the title empty and the series view labels it after the TMDB overlay. Synthetic season names stay, because they key persisted episode progress. - The phone remote-control page, which follows the first browser language with a translation and sets <html lang>. Removes the dead getStatusMessage(), the unused favorites layout and the translateWithFallback() helpers whose keys now exist. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(remote-control): keep the remote build off shared-interfaces The language resolver imported the Language enum, which made remote-control-web depend on shared-interfaces. Its build-performance chain then hit Nx's recursive-invocation guard through the existing shared-interfaces/shared-logging build loop, failing the Electron E2E and performance journey builds. The resolver now keeps its own list of translation codes, and a spec checks it against the locale files the page loads. Also drops the deleted favorites layout from the zoneless checklist, whose guard spec requires ticked entries to exist. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * perf(journeys): raise the launch DOM mutation baseline for translated attributes Launch now sets 569 DOM mutations before the first dashboard card instead of 557 (identical in all three CI iterations). The extra twelve come from attributes this PR moved from static English to translated bindings on the launch path: the window-control labels and tooltips on Linux, the hero carousel and slide roles, and the rail scroll-button labels. A translated attribute is a binding set after the element is attached, so each costs a mutation. Accepted as a deliberate trade-off; it needs the perf-baseline-increase label.

# Zoneless change-detection migration
|
||
|
||
Working checklist for plan item C6 of the performance journeys plan: move the
|
||
renderer (`apps/web`) from zone.js to `provideZonelessChangeDetection()`.
|
||
The win is measured with the change-detection tick counters described in
|
||
[performance journeys](performance-journeys.md#change-detection-ticks); the
|
||
[idle work audit](idle-work-audit-2026-09.md) found the Eager roots that
|
||
re-render on every tick. Update this file in the same PR that converts an item.
|
||
|
||
The inventory was taken on `e8b181fce` (2026-10-04, Angular 22.1.6). Run
|
||
`pnpm nx run electron-backend-e2e:test-performance-harness` after editing the
|
||
Eager list: `zoneless-migration.spec.ts` fails when the list and the code
|
||
disagree, so a new Eager component cannot land unnoticed and a converted one
|
||
must be ticked here.
|
||
|
||
## Starting point
|
||
|
||
- **OnPush is already the default.** Since Angular 22 an unset
|
||
`changeDetection` means OnPush, and the old `Default` strategy is spelled
|
||
`ChangeDetectionStrategy.Eager`. Only components that set `Eager` are
|
||
checked on every tick. `ChangeDetectionStrategy.Default` is not used.
|
||
- **Renderer bootstrap.** `apps/web/src/app/app.config.ts` provides
|
||
`provideZoneChangeDetection({ eventCoalescing: true })` and
|
||
`apps/web/project.json` builds with `"polyfills": ["zone.js"]`.
|
||
`apps/remote-control-web` does the same; it is a separate app and outside
|
||
this migration unless a step says otherwise.
|
||
- **Unit tests already run zoneless.** Every `src/test-setup.ts` (apps/web,
|
||
apps/remote-control-web and 24 libs) calls `setupZonelessTestEnv` and loads
|
||
`zone.js`/`zone.js/testing` only for `fakeAsync` and `waitForAsync`. A
|
||
component that passes its specs is therefore not proof of zone-free
|
||
production behavior when the spec calls `fixture.detectChanges()` itself.
|
||
- **IPC callbacks never ran in the Angular zone.** `window.electron.on*`
|
||
listeners arrive through `contextBridge` and are not zone-patched, so every
|
||
one that works today already writes signals or calls `NgZone.run`.
|
||
- **Counters before the migration** (macOS, from
|
||
[performance journeys](performance-journeys.md#change-detection-ticks)):
|
||
`renderer.cdTicksToFirstCard` 20–21 (the one-tick zone.js race),
|
||
`renderer.cdTicksIdle30s` 3, `renderer.cdTicksToFirstPage` 22;
|
||
`renderer.cdTicksToPlaying` has no recorded run yet.
|
||
|
||
## PR sequence
|
||
|
||
1. [ ] Keep `@ngrx/store-devtools` out of production bundles (#1810, open). Not a
|
||
zone change; it lowered `renderer.initialBytes` before the migration
|
||
starts moving it.
|
||
2. [x] This inventory and its guard spec.
|
||
3. [ ] Per-project PRs, in this order, each converting the project's Eager
|
||
components and fixing its zone-dependent sites while zone.js stays on:
|
||
`libs/ui/*`, `libs/workspace/*`, `libs/playlist/*`, `libs/portal/*`,
|
||
playback (`libs/ui/playback`, `libs/playlist/m3u/feature-player`),
|
||
`apps/web`. Each reports the tick counters before and after and runs the
|
||
affected unit and E2E tests.
|
||
4. [x] `provideZonelessChangeDetection()` behind a build-time
|
||
`fileReplacements` flag, off by default; the three implemented journeys
|
||
(J1-J3; J4 is still planned) and the Electron E2E suite run with it on
|
||
(see [Zoneless flag](#zoneless-flag)).
|
||
5. [ ] Flag on by default, `zone.js` out of `polyfills`, new tick baselines
|
||
(`renderer.cdTicksIdle30s` and any counter that becomes deterministic once
|
||
the zone.js race is gone).
|
||
|
||
## Eager components
|
||
|
||
65 production files, 66 components (`epg-progress-panel.component.ts` holds
|
||
two). Tick an entry by deleting `changeDetection: ChangeDetectionStrategy.Eager`
|
||
(or setting OnPush) once its template state is signals, signal inputs or
|
||
explicitly marked. The guard spec compares the unticked entries with the
|
||
files whose component metadata still sets
|
||
`changeDetection: ChangeDetectionStrategy.Eager` (comments do not count).
|
||
The settings sections read form values in their templates and the parent
|
||
patches the form outside their events (Discard, backup import, the EPG file
|
||
picker), so each marks itself on the form's `events` through
|
||
`markSectionForCheckOnFormEvents` (`apps/web/src/app/settings`).

Test-only files that set Eager are not listed; they do not ship. The guard
|
||
skips every `*.spec.ts` / `*.test.ts` file with or without a suffix of one
|
||
or more segments (`*.spec-stubs.ts`, `*.test-helpers.ts`,
|
||
`*.test-data-stubs.ts`, …),
|
||
`test-setup.ts` and `test-stubs/` directories.
|
||
|
||
## Zone-dependent sites
|
||
|
||
Plain (non-signal) fields read by a template and written from a callback
|
||
that is not an Angular template event. Under zone.js the next tick happens to
|
||
refresh an Eager view; under zoneless nothing schedules one. Each fix makes
|
||
the field a signal (or a `computed`), or writes it through one.
|
||
|
||
| Done | Site | What depends on the zone | Owning PR |
|
||
| --- | --- | --- | --- |
|
||
| [x] | `libs/playlist/m3u/feature-player/src/lib/video-player/video-player.component.ts` `onChannelNumberInput`/`clearChannelNumberInput` | 2 s `window.setTimeout` hides the channel-number overlay through plain `showChannelNumberOverlay`/`channelNumberInput` | playback |
|
||
| [x] | same file, `applySettings` and the settings `effect()` | IndexedDB `storage.get(...).subscribe` and an effect assign plain `playerSettings`, which picks the player in the template | playback |
|
||
| [x] | `libs/playlist/shared/ui/src/lib/recent-playlists/playlist-item/playlist-item.component.ts` `checkPortalStatus` | plain `portalStatus` assigned after `await` in `ngOnInit` (PWA only: skipped when source health is supported) | playlist |
|
||
| [x] | `libs/playlist/shared/ui/src/lib/recent-playlists/playlist-info/playlist-info.component.ts` (EPG clear and EPG file pick handlers) | plain `playlist` reassigned after `await` | playlist |
|
||
| [x] | `libs/playlist/import/feature/src/lib/stalker-portal-import/stalker-portal-import.component.ts` (device-id derivation) | `form.patchValue` after `await`; no fix needed: while derivation is on `hasManualDeviceIds` is false whatever the IDs are, the controls write their own DOM values, and typing goes through value-accessor listeners that mark the view | playlist |
|
||
| [x] | `libs/portal/stalker/feature/src/lib/stalker-live-stream-layout/stalker-live-stream-layout.component.ts` (favorites load) | `favorites` Map filled in a `subscribe` without `markForCheck`; the component is OnPush already, so this is a latent bug today | portal |
|
||
| [x] | `libs/portal/xtream/feature/src/lib/portal-channels-list/portal-channels-list.component.ts` (favorites load) | same pattern; the neighbouring `favoriteMarks.changes$` handler does call `markForCheck` | portal |
|
||
| [x] | same file, programme dialog `afterClosed` | deletes from `epgPrograms`/`currentProgramsProgress` after `await` without marking | portal |
|
||
| [x] | `apps/web/src/app/settings/settings-backup.facade.ts` (backup import) | `change` listener on a detached file input → `hydrateFromStore()`; section templates read `form().value.theme`/`coverSize`; each section now marks itself on its form's `events` (`markSectionForCheckOnFormEvents`), which `settings.component.form.spec.ts` guards without a forced render | apps/web |
|
||
| [x] | `libs/ui/epg/src/lib/epg-guide/epg-guide.component.ts` (jump to now, keyboard focus) | `afterNextRender` registered from CDK/RxJS callbacks; zone.js followed them with a tick, zoneless schedules no render, so the guide opened at midnight. It now marks itself when it registers the hook. Found by `epg-guide.e2e.ts` on the zoneless build | flag |
|
||
| [ ] | `libs/ui/remote-control/src/lib/remote-control/remote-control.component.ts` | plain `isLoading`/`error`/`status` written after `await` and from a 2 s `setInterval` | only if `apps/remote-control-web` goes zoneless |
|
||
|
||
## Explicit zone and change-detector calls
|
||
|
||
They keep working under zoneless (`NgZone` becomes `NoopNgZone`, so `run`
|
||
and `runOutsideAngular` just call through). Remove them in the flip PR, not
|
||
before: with zone.js on they still matter.
|
||
|
||
- [x] `apps/web/src/app/settings/settings-unload-guard.service.ts`: two
|
||
`zone.run` calls around the window-close dialog (IPC
|
||
`onWindowCloseRequested` and `beforeunload`).
|
||
- [x] `libs/ui/playback/src/lib/embedded-mpv-player/embedded-mpv-session-controller.ts`:
|
||
`runOutsideAngular(() => setInterval(...))` for the position poll;
|
||
`embedded-mpv-session-controller.position.spec.ts` asserts the call and
|
||
changes with it.
|
||
- [ ] `libs/workspace/dashboard/data-access/src/lib/dashboard-data.service.ts`:
|
||
18 `ngZone.run(() => signal.set(...))` calls, all redundant around signal
|
||
writes.
|
||
- [ ] `libs/workspace/dashboard/data-access/src/lib/dashboard-source-expiry.service.ts`:
|
||
one `ngZone.run` around a signal update.
|
||
- `ChangeDetectorRef` in `stalker-live-stream-layout.component.ts`
|
||
(4 × `markForCheck`, 1 × `detectChanges` before measuring a row) and
|
||
`portal-channels-list.component.ts` (3 × `markForCheck`, 2 ×
|
||
`detectChanges`): correct under zoneless; replace the Maps with signals in
|
||
the portal PR if it stays small.
|
||
|
||
## Checked and signal-safe
|
||
|
||
No change needed; recorded so the flag PR knows where to look if a journey
|
||
regresses. Embedded MPV and external players are the riskiest paths because
|
||
their events arrive over IPC.
|
||
|
||
- **IPC listeners** (17 registrations): app update status, external player
|
||
sessions, window close and window state, player errors, playlist open
|
||
requests, embedded MPV sessions, playback history gate, downloads,
|
||
recordings, playlist refresh, DB operation and save progress, EPG progress,
|
||
playback position updates, channel change and remote-control commands. All
|
||
write signals, signal stores or NgRx, or have no UI state.
|
||
- **Player libraries** (video.js, mpegts.js, hls.js, artplayer, shaka, native
|
||
`<video>`): callbacks bump signals in the control adapters or emit outputs
|
||
whose parent handlers write signals.
|
||
- **Observers** (13 Intersection/Resize/Mutation observers) and **document
|
||
and window listeners** (~40): signals or DOM only. `@HostListener`
|
||
bindings are Angular listeners and mark their view.
|
||
- **Timers** (~130 `setTimeout`/`setInterval`/rAF/`queueMicrotask`): all
|
||
write signals, touch the DOM or focus, or have no UI state, apart from the
|
||
two in the table above.
|
||
- **Dialogs and snackbars** (20 `afterClosed`/`onAction` sites): signals,
|
||
stores, outputs or navigation, apart from the one in the table above.
|
||
- No production code uses `NgZone.onStable`, `onMicrotaskEmpty`, `isStable`,
|
||
`ApplicationRef.tick()`, `Zone.current` or `ngDoCheck`.
|
||
|
||
## Build, tests and runtime details
|
||
|
||
- [ ] `provideServiceWorker(..., { registrationStrategy:
|
||
'registerWhenStable:30000' })`: under zoneless "stable" means no pending
|
||
tasks. The 30 s bound still registers the worker; check the PWA build in
|
||
the flag PR.
|
||
- [ ] `change-detection-tick-counter.ts` wraps `ApplicationRef._tick`, which
|
||
the zoneless scheduler also calls, so the counters stay comparable.
|
||
- [ ] Specs that need zone.js: `fakeAsync` in
|
||
`playlist-switcher.component.spec.ts` and `stalker-live-navigation.spec.ts`,
|
||
`waitForAsync` in 13 files. They keep `zone.js/testing` until rewritten;
|
||
removing zone.js from the build polyfills does not affect them.
|
||
- [ ] Unreferenced leftovers to delete in the flip PR:
|
||
`apps/web/src/polyfills.ts`, `apps/web/src/polyfills-test.ts`,
|
||
`apps/web/src/setup-jest.ts` (no project, tsconfig or Jest config uses
|
||
them).
|
||
|
||
## Zoneless flag
|
||
|
||
`app.config.ts` takes its change-detection providers from
|
||
`apps/web/src/environments/change-detection.providers.ts`
|
||
(`provideZoneChangeDetection({ eventCoalescing: true })`). The
|
||
`electron-performance-zoneless` and `electron-e2e-zoneless` web
|
||
configurations are their base configuration plus one `fileReplacements`
|
||
swap to `change-detection.providers.zoneless.ts`
|
||
(`provideZonelessChangeDetection()`); a test in
|
||
`performance-build-config.spec.ts` pins that and refuses the swap in any
|
||
other configuration. zone.js stays in the polyfills, so these builds log
|
||
NG0914 in dev mode and nothing schedules through the zone. The Electron app
|
||
loads the renderer from `dist/apps/web`, so rebuilding only the web app
|
||
switches an existing Electron build:
|
||
|
||
```bash
|
||
pnpm nx run electron-backend:build-performance # or build-e2e
|
||
pnpm nx run web:build:electron-performance-zoneless # or electron-e2e-zoneless
|
||
cd apps/electron-backend-e2e
|
||
../../node_modules/.bin/playwright test --config=playwright.journeys.config.ts
|
||
../../node_modules/.bin/playwright test --grep-invert packaged
|
||
```
|
||
|
||
Do not run `pnpm run perf:journeys` or `pnpm nx run electron-backend-e2e:e2e`
|
||
afterwards: their build dependencies restore the zone.js renderer.
|
||
|
||
First measurement (macOS, 2026-10-04, the six OnPush PRs merged locally on
|
||
the flag branch; the same integration build measured with the flag off and
|
||
on, five iterations each):
|
||
|
||
| Counter | flag off | flag on |
|
||
| --- | --- | --- |
|
||
| `renderer.cdTicksToFirstCard` | 22, 20, 22, 21, 21 | 7, 7, 7, 7, 7 |
|
||
| `renderer.cdTicksIdle30s` | 4, 4, 4, 4, 4 | 3, 3, 3, 3, 3 |
|
||
| `renderer.cdTicksToFirstPage` | 22 (all) | 8 (all) |
|
||
| `renderer.cdTicksToPlaying` | 16, 15, 15, 17, 15 | 6, 8, 10, 10, 7 |
|
||
| DOM mutations J1 / J2 / J3 | 553 / 1,603 / 6,182 | 553 / 1,603 / 6,182 (one J3 iteration 6,199, as on master) |
|
||
| `spawnToFirstCardMs` p50 | 3,071 | 828 |
|
||
| `clickToFirstPageMs` p50 | 82.8 | 80.4 |
|
||
| `clickToLoadedMetadataMs` / `clickToPlayingMs` p50 | 94.8 / 268.7 | 158.3 / 409.3 |
|
||
|
||
J1 and J2 tick counts become deterministic without the zone.js one-tick
|
||
race, and the DOM mutations are unchanged, so nothing renders differently.
|
||
J3's tick count still varies with player events and its wall-clock
|
||
numbers rose locally; the machine was shared with other runs (load 26 to 58
|
||
during these two runs, master itself read 363.8 ms `clickToPlayingMs` p50
|
||
earlier the same day), so judge J3 on the CI runner before the flip.
|
||
|
||
Electron E2E suite on `electron-e2e-zoneless` (all specs except the
|
||
packaged frame-copy ones): 203 passed, 7 skipped, 3 failed. `epg-guide`
|
||
failed on every run and is fixed above; `playlist-auto-refresh` passed on
|
||
`--repeat-each=2`; `dash-clearkey` "reopens from recent and favorites" is the
|
||
known local flake (it fails as often on master). The IPC-driven paths
|
||
passed zoneless: external-player launch states and the MPV/VLC DASH
|
||
fallbacks in `dash-clearkey`, the MPV double-click gate in `settings`,
|
||
`remote-control`, `picture-in-picture` and `stream-info`. Their state reaches
|
||
the renderer over IPC into signals and never ran in the zone. Embedded MPV
|
||
playback itself is covered only by the packaged frame-copy E2E, which these
|
||
runs left out; run it on a packaged zoneless build before the flip.
|
||
|
||
## Measuring a PR
|
||
|
||
Build `electron-performance` and run the journeys as described in
|
||
[performance journeys](performance-journeys.md), then paste
|
||
`renderer.cdTicksToFirstCard`, `renderer.cdTicksIdle30s`,
|
||
`renderer.cdTicksToFirstPage` and `renderer.cdTicksToPlaying` before and
|
||
after. While zone.js is on, removing Eager does not change the number of
|
||
ticks, only the work per tick; expect the counters to stay put until the flag
|
||
PR and the template work (DOM mutations, profile time) to drop.
