Translation edits now compile through the official paraglideVitePlugin. The local adapter discovers and validates colocated catalogs, writes their aggregate JSON atomically, and reports catalog errors. Paraglide owns compilation, generated-output cleanup, caching and HMR. This removes the project's duplicate compiler cache and output hashing.

Upgrade @inlang/paraglide-js to the published 2.29.0 release and remove the dependency patch. The release includes the changes merged in opral/paraglide-js#820: development HTTP error responses, pending compilation shutdown, and invalidation of caches from a queue that finishes during shutdown.

Group catalog and locale-settings events for 100 ms inside the adapter. A sequential watchChange hook lets preparation finish before the official plugin processes the same event. The adapter preserves server.watch, including custom awaitWriteFinish options and watch: null, so ordinary JS and CSS edits no longer receive the global write-stability delay. This event window does not guarantee that an arbitrary multipart write has finished.

Markdown generation runs after the initial Paraglide compilation and refreshes from generated message modules. Its state is shared across build environments so Nitro publishes matching localized artifacts and manifests. Strict compiler validation remains proposed separately in opral/paraglide-js#794; the adapter continues to use the official SDK checks while preserving automatic discovery and duplicate-message detection.

Shutdown waits for preparation and compilation already started. Events not delivered before shutdown are handled by the next initialization. The cache regressions pause a real compiler read, save another revision, and close Vite before the second event is delivered. Only those fixtures configure a delayed watcher to reproduce stale caches; both warm and fresh-process restarts must publish the latest translation.

Validation:

  • Formatting, lint and application/Node type checks.
  • 530 application tests and 31 release tests.
  • 144 tooling tests, including three regressions that fail with the old global watcher configuration.
  • 18 i18n E2E tests for server functions, redirects and hydration.
  • 22 production i18n E2E tests for SSR, locale switching, concurrent requests, Markdown and SEO.
  • Real Bun development server: update and restore a home translation in Chromium without JavaScript errors.
  • JS/CSS HMR fixture: retain component state and a single document navigation. Five samples per configuration measured a median of 3.7 ms with the scoped delay versus 124.7 ms with the previous global setting; this is a local comparison, not a general performance guarantee.
  • Cache mutation check: removing only shutdown cache invalidation in memory makes both restart regressions fail with the previous translation; the published package passes both.

Summary by CodeRabbit

  • New Features
    • Translation catalog changes are validated during development, with clear error feedback when catalogs or settings are invalid.
    • After errors are corrected, the development app recovers automatically and reloads with updated translations.
    • Markdown content backed by translations now updates its generated snapshots when messages change.
  • Documentation
    • Updated guidance covers translation generation, validation, development recovery, and build and CI workflows.

A settings or catalog write can finish inside Chokidar's event suppression
window after the generator has read incomplete JSON, leaving development
requests blocked until another edit.

Schedule a trailing read through the existing generation queue and drain
it on shutdown. Keep the global Vite watcher configuration unchanged.

Add real fs.watch regressions for incomplete settings and catalogs and
shutdown with a pending read. All three fail against the previous plugin.

Validation:
- 134 tooling tests pass.
- 530 application tests pass.
- 18 fixture and 22 production i18n E2E tests pass.
- check:ci, typecheck and typecheck:node pass.

📝 Walkthrough

The i18n pipeline now prepares locale aggregates before Paraglide compilation and coordinates catalog updates through Vite. The Markdown plugin updates generated artifacts from Paraglide changes. Tests and documentation cover generation, watcher behavior, recovery, and shutdown.

Changes: i18n pipeline and generated content

Layer / File(s) Summary
Prepare locale aggregates
tooling/i18n/prepareMessages/index.ts, tooling/i18n/generateMessages/index.ts, tooling/i18n/generateMessages/__tests__/generateMessages.test.ts
prepareMessages validates settings and writes formatted locale aggregates only when content changes. generateMessages prepares the aggregates before invoking the Paraglide compiler. Tests check generated output and modification times.
Catalog preparation and Paraglide integration
tooling/i18n/i18nPlugin/index.ts, tooling/i18n/i18nPlugin/__tests__/*, tooling/i18n/i18nPlugin/__tests__/i18nPlugin.watchIsolation.test.ts, docs/i18n.md, package.json
The i18n plugin prepares aggregates for settings and catalog changes, reports preparation errors, and uses paraglideVitePlugin. Tests cover watcher settings, recovery, shutdown, partial writes, and generated output. The documentation describes the generation and recovery flows; @inlang/paraglide-js is updated to 2.29.0.
Markdown generation and refresh
tooling/markdown/markdownPlugin/index.ts, tooling/markdown/markdownPlugin/__tests__/markdownPlugin.test.ts
The Markdown plugin shares initial generation between build and development, tracks returned dependencies, and refreshes for configured-source and paraglide changes. The integration test checks translated titles and message updates.

Saving a catalog or locale configuration in multiple writes can expose
incomplete JSON and leave development requests blocked after a missed event.

Use the Vite watcher's public awaitWriteFinish option with a 100 ms
stability threshold and 10 ms polling interval. Preserve an explicitly
disabled watcher and remove the trailing read and custom timer cleanup.

The shared watcher now delays source and CSS updates until writes settle.
Document that tradeoff and cover completed settings/catalog writes without
transient errors, alongside recovery from persistent invalid input.

Validation:
- 134 tooling tests pass, including 9 watcher tests.
- check:ci and typecheck:node pass.
- Headless Chromium verifies JavaScript and CSS HMR with page state preserved.
- Five local HMR samples have a median of 123.2 ms with stabilization,
  compared with 5.1 ms without it.
- The full Bun development server updates a real home translation and
  restores it without page errors.

O ponto sobre recuperar eventos não entregues na próxima inicialização continua compatível com o contrato descrito na thread resolvida. O encerramento aguarda o trabalho já iniciado; não precisa forçar outra compilação em todo fechamento.

Em 2c4cc2e, a dependência passou para o Paraglide 2.29.0, que já publica as correções do PR upstream #820. O patch local foi removido. Também retirei a alteração global de server.watch.awaitWriteFinish: a espera de 100 ms agora agrupa apenas eventos de catálogos e configurações de idioma, preservando as opções do watcher escolhidas pelo projeto.

Os testes de cache continuam exigindo a tradução mais recente após reiniciar no mesmo processo ou em um novo processo Node. Apenas essas duas fixtures configuram eventos atrasados para reproduzir a corrida. Retirar a invalidação de cache somente na memória do processo fez ambos falharem com a tradução antiga; com o pacote publicado intacto, ambos passaram. As três novas regressões do watcher também falharam com a configuração global anterior e passaram após sua remoção.

O CI deste commit passou. Localmente passaram lint, tipos, 530 testes da aplicação, 144 de tooling, 31 de release, 18 E2E de i18n e 22 E2E de i18n em produção. No app iniciado com Bun, a tradução foi alterada e restaurada no navegador sem erro de JavaScript. Mantive a regra do projeto para comentários: explicar motivos e restrições, sem acrescentar docstrings que apenas repitam a implementação para atingir uma porcentagem genérica de cobertura.

A revisão automática disponível cobre 80070a5 e não apontou novos comentários acionáveis. A tentativa para 2c4cc2e foi impedida pelo limite de cota informado no resumo, portanto sua cobertura termina no commit anterior. O último ajuste apenas retorna diretamente a Promise da preparação, preservando o hook sequencial; seus gates locais e o CI passaram.

Use the published shutdown and development-error fixes and remove the
local dependency patch. Group only catalog and locale-settings events,
then await preparation before the official plugin handles each event.
Preserve application watcher settings and normal JS/CSS HMR latency.

Cover default, disabled and custom write stabilization. Keep delayed
watch events local to the two shutdown-cache regression fixtures.
