feat(dev): align test-dev-server with Vite dev server by h-a-n-a · Pull Request #9668 · rolldown/rolldown

h-a-n-a · 2026-06-08T10:57:01Z

Summary

Stacked on #9652.

Restructures packages/test-dev-server so it tracks Vite's full-bundle-mode dev
server (packages/vite/src/node/server/environments/fullBundleEnvironment.ts),
rather than carrying its own ad-hoc shape. The goal is to let dev-engine work be
exercised inside the rolldown repo against a server whose error handling,
middleware, and reload behavior match Vite's — so behavioral regressions in the
dev() engine surface here before they reach Vite.

A literal 1:1 port isn't possible: the test harness depends on pieces Vite
doesn't have. Those are kept intentionally:

the standalone connect + ws server (Vite reuses its own HTTP/HMR transport),
the disk-serving path for the node target,
the /_dev/status endpoint plus buildSeq / moduleRegistrationSeq test
instrumentation.

Constraint: the shared rolldown HMR runtime
(crates/rolldown_plugin_hmr/src/runtime/runtime-extra-dev-default.js) is not
touched — every change lives in packages/test-dev-server.

Structure

The flat dev-server.ts is split to mirror Vite's layout:

test-dev-server	Vite equivalent
`src/environments/full-bundle-dev-environment.ts` (`FullBundleDevEnvironment`)	`environments/fullBundleEnvironment.ts`
`src/middlewares/{memory-files,index-html,trigger-lazy-bundling,status}.ts`	`server/middlewares/*`
`src/{clients,memory-files,fallback-html}.ts`, `src/utils/{debounce,prepare-error}.ts`	Vite helpers
`src/dev-server.ts`	`server/index.ts` (connect/http/ws transport + middleware wiring only)

FullBundleDevEnvironment now owns the dev engine, the in-memory output, the
client registry, and the lastBuildError / fullReloadPending state.

Behavior ported from Vite

Error replay: lastBuildError is cached from either callback channel
(onOutput / onHmrUpdates), broadcast on break, and replayed on client
connect so the overlay survives a refresh; it's cleared on a successful build
from either channel.
Build-error overlay (error-overlay.ts): stand-in for Vite's client
overlay, injected into the generated index.html and the "Bundling in
progress" spinner. Runs as its own ws client alongside the rolldown HMR
runtime; because HMR patches are delivered per-client, recovery is signalled
by a broadcast build:ok (HMR recovery) and a reload (full-build recovery).
prepareError (utils/prepare-error.ts): port of Vite's helper — strips
ANSI via node:util's stripVTControlCharacters and copies only the fields
the overlay needs (message/stack/id/frame/plugin/pluginCode/loc).
Reload handling: deferred full reload (fullReloadPending), debounced
reload, conservative stale-output regen guard
(hasStaleOutput && !lastBuildErrored && initialBuildCompleted), and
noop/empty HMR-batch filtering.
Serving targets: browser target serves from memory with the spinner +
skipWrite; node target serves from disk behind a request gate.

Docs

Reconciles meta/design/dev-engine.md §2: it claimed lastBuildError clears
only on a successful onOutput, but Vite (and now this port) also clears it on a
successful onHmrUpdates.

Testing

pnpm test:fixtures (9) and pnpm test:browser (10) pass, including a new
browser.spec.ts case asserting the build-error overlay appears on a break and
clears on recovery.

Restructures `packages/test-dev-server` so it tracks Vite's full-bundle-mode dev server (`packages/vite/src/node/server/environments/fullBundleEnvironment.ts`), rather than carrying its own ad-hoc shape.

A literal 1:1 port isn't possible: the test harness depends on pieces Vite doesn't have. Those are **kept** intentionally: - the standalone connect + `ws` server (Vite reuses its own HTTP/HMR transport), - the **disk**-serving path for the node target, - the `/_dev/status` endpoint plus `buildSeq` / `moduleRegistrationSeq` test instrumentation. **Constraint:** the shared rolldown HMR runtime (`crates/rolldown_plugin_hmr/src/runtime/runtime-extra-dev-default.js`) is **not** touched — every change lives in `packages/test-dev-server`. ## Structure The flat `dev-server.ts` is split to mirror Vite's layout: | test-dev-server | Vite equivalent | | --- | --- | | `src/environments/full-bundle-dev-environment.ts` (`FullBundleDevEnvironment`) | `environments/fullBundleEnvironment.ts` | | `src/middlewares/{memory-files,index-html,trigger-lazy-bundling,status}.ts` | `server/middlewares/*` | | `src/{clients,memory-files,fallback-html}.ts`, `src/utils/{debounce,prepare-error}.ts` | Vite helpers | | `src/dev-server.ts` | `server/index.ts` (connect/http/ws transport + middleware wiring only) | `FullBundleDevEnvironment` now owns the dev engine, the in-memory output, the client registry, and the `lastBuildError` / `fullReloadPending` state. ## Behavior ported from Vite - **Error replay:** `lastBuildError` is cached from either callback channel (`onOutput` / `onHmrUpdates`), broadcast on break, and replayed on client connect so the overlay survives a refresh; it's cleared on a successful build from **either** channel. - **Build-error overlay** (`error-overlay.ts`): stand-in for Vite's client overlay, injected into the generated `index.html` and the "Bundling in progress" spinner.

## Summary Rebuilds the `@rolldown/test-dev-server` **browser** test harness around an in-process dev server, mirroring Vite's playground harness. The old model ran each playground as a `pnpm serve` subprocess on a hand-picked port kept in two synced registries; this replaces it with a server that runs inside each vitest worker on an OS-assigned port, discovered from the spec's own path. **Adding a browser test is now a folder + a spec, with zero central edits.** Stacked on #9668. Rationale and as-built detail live in `meta/design/dev-server-test-harness.md`. ## Server entry point (`src/`) - New **`createDevServer(config, opts?) → { url, port, close }`** — binds `port 0` (OS-assigned) and resolves once the first bundle is actually being served (a navigation never lands on the spinner). - **Listen-before-build**: bind the socket → read the bound port → inject it into `experimental.devMode.port` → build. This makes auto-port work even though the HMR websocket port is baked into the bundle, without touching the shared runtime. - New `loadDevConfig(dir)`, an injectable `Logger` (server output → `serverLogs`), and a real `DevServer.close()` (ws server + clients + `httpServer.close()` + `env.close()`). `serve()` (the CLI/fixtures path) delegates to the same class. ## Harness (`tests/`) - In-process server per spec file; one shared Chromium (`launchServer` in global setup; each file connects and opens one page); teardown via the server's own `close()` — no `killPort`, no orphaned subprocesses. - Spec-path discovery: `vitest.config.e2e.mts` globs `playground/**/*.spec.ts`; global setup copies only the selected playgrounds into `playground-temp/`. - A `~utils` surface (`page`, `serverUrl`, `editFile`, `waitForBuildStable`, `untilBrowserLogAfter`, …) and URL-keyed `/_dev/status` helpers shared with the node fixtures suite. - Removed the subprocess machinery: `browser.spec.ts`, `vitest-setup-browser.ts`, `tests/test-utils.ts`, `tests/src/config.ts` (the port registry), and `vitest.config.browser.mts`. ## Lazy-compilation consolidation The four sibling `lazy-*` playgrounds (`lazy-compilation`, `lazy-aliased-import`, `lazy-shared-module`, `lazy-nested-dynamic-import`) are merged into **one** `lazy-compilation/` co-tenant playground: one `dev.config.mjs`, one `index.html`, `main.js` importing a `setup.js` per scenario sub-folder (`basic/`, `aliased-import/`, `shared-module/`, `nested-dynamic-import/`), and four specs sharing one cold-start `serve.ts`. Safe because lazy chunks compile only on first dynamic import, so each spec's own per-file server stays virgin for its scenario even though all four live in one project. ## Docs Rewrote `meta/design/dev-server-test-harness.md` down to principles + as-built implementation; folded in and deleted `dev-server-browser-tests.md`; updated `tests/README.md`. ## Verification - `pnpm typecheck` (tests) — clean - `pnpm test:browser` — 10/10 green (`hmr-full-bundle-mode` + the four lazy scenarios) - `knip` (lazy-compilation workspace) — clean 🤖 Generated with [Claude Code](https://claude.com/claude-code)

## [1.1.2] - 2026-06-18 ### 📝 Notable tsconfig behavior changes These ship via the `oxc_resolver` 11.21.3 bump (#9841) and affect `resolve.tsconfigPaths` (Vite 8 resolves through oxc-resolver): - **Honor explicit non-TS extensions in `include`** (oxc-project/oxc-resolver#1213). `compilerOptions.paths` now resolve for importers whose extension is explicitly listed in a tsconfig's `include` (e.g. `src/**/*.vue`, `src/**/*.svelte`). Previously oxc-resolver filtered importers by extension before evaluating the `include` globs, so a `.vue`/`.svelte` file listed in `include` never matched its project and its `paths` were skipped. This unblocks the default create-vite Vue + TS layout (a solution-style root plus a referenced `tsconfig.app.json` that declares `paths` and `include: ["src/**/*.ts", "src/**/*.vue"]`). Matches vue-tsc and svelte-check, which register these extensions via TypeScript's `extraFileExtensions`. - **No fallback to the outermost tsconfig in auto-discovery** (oxc-project/oxc-resolver#1220). Auto-discovery no longer attaches the topmost ancestor `tsconfig.json` to a file that no project actually owns (via `files` / `include` / project references). Previously such a file inherited the outermost ancestor's `paths` / `baseUrl`, leaking aliases into files that project does not own. oxc-resolver now returns no config in that case, matching tsserver / typescript-go, which route such files to an inferred project with no aliases. ### 🚀 Features -
