refactor: simplify Effect server architecture by ScriptedAlchemy · Pull Request #101 · rstackjs/rsbuild-plugin-react-router

ScriptedAlchemy · 2026-07-21T00:53:02Z

Summary

Create one scoped Effect ManagedRuntime per plugin setup.
Let the runtime own parent-side transform workers, route watchers, delayed prewarm work, resource finalizers, and background fibers.
Keep worker execution, browser/runtime templates, generated client code, and synchronous Rsbuild state machines Effect-free.
Compose Node-side config, manifest, prerender, typegen, and resource workflows with Effect where it removes Promise/cleanup coordination.
Update Effect to 3.22.0 and Rstest to 0.11.4 with per-file isolation enabled.
Merge current main, including preservation of in-memory dev output and explicit writeToDisk overrides.

Maintainability

One runtime creation site and one ordered, idempotent disposal policy.
Native Scope and FiberSet replace duplicate worker/watcher/prewarm close registration and manual cleanup aggregation.
Production src/ is 94 lines smaller than the exact pre-Effect baseline.
Additional branch lines are regression tests and benchmark infrastructure; total LOC is diagnostic, not a gate.

Validation

pnpm test — 58 files, 670 tests passed; includes all TypeScript project checks.
pnpm build
pnpm test:package-interop
Emitted worker and browser/template entries contain no Effect imports or runtime references.
Prior fixed-SHA CI: unit/build/publint, 721-test React Router ecosystem suite, E2E, CodeQL, and package preview passed.

Performance

Paired CI compared Effect head d005c48 with the exact pre-Effect baseline 8fdee93 on the same runners:

All dev fixtures: wall -2.2%, readiness -2.0%, update/HMR -4.8%.
Large dev fixture: wall -2.9%, readiness -3.5%, update/HMR -4.5%.
Complex app: cold -0.8%, warm -1.4%, dev +0.4%; all within measured noise.
Production builds ranged from -2.3% to +0.1%, except the large fixture at +2.7% inside a ±3.6% noise band (inconclusive, not a detected regression).
Effect is absent from the worker entrypoint, so worker startup does not load an Effect runtime.

…typing - one resolveAppPackagePath/getPackageVersion pair in plugin-utils (react-router version now resolved from the app, not the plugin install) - extract createRouteManifestItem from the dev-manifest effect and collapse the per-chunk module lookups - replace Awaited<ReturnType<...>>/Parameters<...>[5] gymnastics with the exported ReactRouterManifestForDev/RouteChunkManifestOptions types - type modePlan webOutput/webOptimization with Rspack config types and drop the as-const noise - dedupe classic server-build options, single rsc-option normalization, inline single-use query helpers, remove plugin factory indirection Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Transformed routes import UNSAFE_withComponentProps and friends from react-router, which only exist from 7.7.0; 7.13 is the lowest v7 line this plugin is tested against (main's previous floor). Widening the peer range to ^7.0.0 let 7.0-7.12 installs pass peer resolution and then fail every classic-mode build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Register the RSC request listener via the server.setup post-callback so it runs after compiled-asset and public-dir middlewares, making it the fallback for anything static serving declines - the same routing semantics as production. This removes the GET/POST and file-extension bypass heuristics that 404'd extension-ful resource routes (e.g. /sitemap.xml) and non-GET/POST resource routes in dev; only /__rsbuild_ internals bypass the handler now.

Wire the prerender config into the RSC mode plan and add an onAfterBuild step that replays upstream's RSC prerender pipeline against the built server bundle's fetch handler: emits <path>/index.html plus <path>.rsc flight payloads (_.rsc for the root), meta-refresh documents for redirects, raw bytes for resource routes, and __spa-fallback.html/.rsc for ssr:false builds. The RSC preview fixture now serves prerendered documents and the SPA fallback like upstream's configurePreviewServer. Classic-mode prerender is untouched. Vendored parity tests rsc/rsc-prerender-test.ts now pass 3/3. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

createReactRouterModePlan is now a thin dispatcher over createClassicModePlan / createRscModePlan with a narrow shared ModePlanContext, so each mode's planner owns only the inputs it uses instead of one 30-field options blob feeding both branches. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The sync script now carries a pinned upstream ref (4cf6e62d0cdf9d7f6e09b0ea10077d7fb0e1b438), refuses to sync from a dirty or mismatched source checkout (--update-pin adopts a new sha), and writes tests/react-router-framework/UPSTREAM.json recording the repository, sha, source dirs, file count, and adapter-owned overlay list. The README documents the pin-update flow and that everything outside the adapter-owned files is generated and must not be hand-edited. corpusVerified is false: 13 checked-in files drift from the pinned sha (a locally added rsc-framework-test.ts plus Rsbuild adaptations and small edits) - recorded in the manifest as an undeclared overlay to classify in a follow-up. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The corpus is repo-owned and rsbuild-adapted; UPSTREAM.json records provenance only. Delete the five checked-in template vite.config.ts files (the adapter generates rsbuild.config.ts and never reads them) and strip vite/@vitejs/@vanilla-extract/vite-plugin/@cloudflare/ vite-plugin/vite-tsconfig-paths entries from corpus package.jsons (never installed - the corpus is not a workspace package and the adapter rewrites fixture deps wholesale). No test file imports 'vite' at top level; remaining matches are fixture template strings the adapter converts. vite-env-only stays: fixture app code imports its macros. Verified: playwright smoke 7/7, test:core 490/490. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

RSC mode silently ignored buildEnd, presets, serverBundles, and subResourceIntegrity from react-router.config - a user's buildEnd hook never fired and serverBundles/SRI produced nothing with no signal. Upstream's RSC vite plugin rejects these with a validation error; assertReactRouterRscConfigSupport now does the same. allowedActionOrigins was also dropped in RSC mode even though react-router's matchRSCServerRequest supports it (upstream's default RSC entry drops it too). Expose it as a virtual/react-router/unstable_rsc/allowed-action-origins module and pass it through the entry template so action-origin restrictions apply. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The RSC mode plan pinned routeChunkConfig.splitRouteModules to false, so a configured 'enforce' never triggered chunk validation. Upstream's RSC vite plugin gates validation on config.splitRouteModules === 'enforce' while chunk splitting itself stays content-detected - pass the resolved config value through to match. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The config factory in integration/helpers/vite.ts now emits rsbuild.config.ts content (pluginReactRouter/pluginReactRouterRSC + pluginReact, pluginMdx when needed) with real option mappings: base->output.assetPrefix, port->server.port+strictPort, assetsInlineLimit->output.dataUriLimit, assetsDir->output.distPath, vanilla-extract via @vanilla-extract/webpack-plugin (deterministic identifiers, realContentHash off, sideEffects workaround). ~35 inline vite.config fixture strings converted across 20+ test files; Vite-only suites (plugin-order validation, @cloudflare/vite-plugin, fs.allow) carry visible describe/test.skip with reasons. The vite-7/vite-8 template pair is collapsed to one (identical under rsbuild), halving template-parameterized suite runs. The adapter's vite.config interception is now a warn-loudly dead path (0 hits across all runs). Verified against captured baselines: no test that passed before fails after; vite-manifests (3), server-bundles dev/build-manifest, spa-mode manifest, and vanilla-extract no-JS suites (3) newly pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Route edits in classic dev now apply through react-refresh instead of full reloads, and loader/action changes trigger client revalidation: - src/dev-hmr.ts: resolves @rsbuild/plugin-react's react-refresh runtime, generates a dev-only HMR runtime virtual module, and maintains an HDR revision module that the dev runtime bumps when a node rebuild commits so the browser revalidates loader data. - route transforms gain a devHmr mode wrapping client route modules with refresh registration; dev-runtime-controller patches route metadata on the client and signals rebuild commits instead of forcing full reloads. - When the react-refresh runtime is absent (or in RSC/build mode), everything falls back to the previous full-reload behavior. Vendored parity tests vite-hmr-hdr-test.ts now pass 3/3 (previously 0/6 pre-template-collapse). vite-dev-test.ts guard: 12 passed, 4 pre-existing failures verified identical without this change. This work was implemented by a subagent whose worktree was lost to a session limit; the change set was recovered by replaying its recorded 54 edit operations and validated byte-for-byte against its partial snapshot.

The helper spawnSyncs 'rsbuild dev' expecting Vite's validate-and-exit startup behavior; rsbuild's dev server never self-terminates, which blocked a suite run indefinitely when a test assumed an error exit. Triage confirmed no plugin or rsbuild bug (config function-form was coincidental): a 30s timeout keeps any such assumption from hanging the harness again. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Two manifest asset-URL bugs: - The dev manifest derived its asset prefix solely from output.assetPrefix, ignoring dev.assetPrefix (Rsbuild's effective prefix in dev, defaulted from server.base). Asset URLs 404'd for any app configuring a dev prefix. resolveEffectiveAssetPrefix now mirrors Rsbuild's per-mode precedence off the normalized config, resolved in onBeforeCreateCompiler. - The build-mode browser manifest was generated at processAssets stage 'additions' (-100), before rspack's realContentHash rename at OPTIMIZE_HASH (2500), so manifest CSS/JS URLs could reference pre-rename hashed names absent from the output. Build-mode manifest generation and emission now run at 'report' (5000), unifying the previously separate SRI deferral; dev keeps 'additions' (no realContentHash pass in dev). test:core 491 -> 499. Classic-mode basename dev/build corpus cases all pass; vanilla-extract build cases pass with the fixtures' realContentHash:false workaround removed (workaround removal lands with the corpus rename commit). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Content-level renames completing the file renames that landed with fb25f5a: viteConfig->rsbuildConfig (77 refs), vitePreview-> rsbuildPreview, viteDevCmd->rsbuildDevCmd, viteMajorTemplates-> bundlerTemplates, Rsbuild-accurate describe/test titles ('Vite CSS'-> 'CSS', 'vite dev'->'rsbuild dev', ...), rsc fixture package scripts now say rsbuild, and UPSTREAM.json gains a complete upstream->corpus renames map (31 entries) so manual upstream comparison survives the renames. The two describe.skip'ed Vite-only suites keep their accurate Vite titles, as do assertions on strings React Router itself emits. Also applies the deferred manifest-fix corpus hunk to the renamed config factory: 'base' now maps to dev.assetPrefix as well (the plugin honors it since fb25f5a) and the vanilla-extract realContentHash:false workaround is removed (manifest reads post-hash names now). Verified: test:core 499; smoke 7/7; hmr-hdr 3/3; css+basename exactly match pre-existing baselines (24 passed / 14 failed / 3 skipped / 1 DNR - zero new failures); corpus greps for vite-flavored helper names come back empty. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Assets referenced only by server code (asset?url imports, .css?url files) are returned to the client as URLs but were never emitted to build/client, 404ing at runtime. Mirroring upstream's ssrEmitAssets + writeBundle move/remove: a node-target processAssets 'report' hook (post-realContentHash, so names are final) relocates emitted static assets into the client output when absent and strips them from the server build; server code-split chunks get a proper async chunkFilename and server-only .css?url output is redirected to the flat static/assets layout while preserving postcss processing. Verified against rsbuild source: dev serves from real disk when writeToDisk is on (setupOutputFileSystem), cleanAll runs before compilations so relocated files survive, and the uniform assetPrefix keeps loader-returned URLs aligned. No rsbuild/rspack built-in covers cross-environment asset sharing (tracedecay-searched), so the relocation module stays. Corpus: build-test + extra-server-environment now 9/9 (combined with the post-realContentHash manifest fix, even code-split CSS passes); smoke 7/7; test:core 506.

tests/react-router-framework/.tmp/ (7,856 materialized fixture files) was accidentally committed by a broad git add during the corpus work, inflating the PR diff massively. Untrack it and ignore fixture scratch, test-results, and playwright reports going forward. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Four-angle review (reuse/simplification/efficiency/altitude) over the RR8 branch diff: - assetPrefix now has a single writer (onBeforeCreateCompiler); the two config-phase assignments are gone and the virtual-module publicPath reads output.assetPrefix locally - RscModePlan drops its routeTransformExecutor/routeChunkOptions sentinels; the one unguarded consumer gates on plan kind - shared parseVersionMajorMinor replaces two divergent react-router version parsers; getPackageVersion memoizes default-resolver lookups - rsc-route-transforms imports CLIENT_NON_COMPONENT_EXPORTS from constants instead of redefining it; SPA_FALLBACK_HTML_FILE is a shared constant across both prerender pipelines; RSC basename/ bootstrap prefixes reuse normalizeAssetPrefix (was 4 copies) - route modules are no longer parsed for analysis in the node transform (client-entry covers every route; disk fallback intact), removing 1-2 redundant SWC parses per route per build - ssr-asset-relocation caches relocated destinations across node compilations (serverBundles, dev rebuilds) skipping steady-state stat/write syscalls; dev-hmr skips redundant mkdir after first bump - react-refresh runtime resolution no longer falls back to a bare root resolve that could bind a different physical instance than the browser graph (silent no-op refresh); unavailable now means the documented full-reload path - devHmr options pass through the mode plan without re-projection; RSC virtual modules share a defaultExport helper; classic createResolveConfig drops its empty-alias conditional Skipped deliberately: the node .css?url filename mapping (documented, empirically-validated tradeoff), hooks-per-mode/discriminated-union mode-plan reshape (deferred, larger), PrerenderConfig type unification (low value vs inference churn), shared classic/RSC alias builder (resolution semantics deliberately differ). manifestChunkNames on RscModePlan was confirmed live (web clientStats), not dead state. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The interop script's hand-rolled plugin API stub predates the onBeforeCreateCompiler registration added for effective-asset-prefix resolution, so CI's build-test failed with 'api.onBeforeCreateCompiler is not a function'. The hook exists on the real Rsbuild plugin API (@rsbuild/core 2.x); only the stub was stale. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Repo-wide sweep found exactly two stale references from the vite-> rsbuild corpus renames (template package name, a comment pointing at a pre-rename test filename) plus one ambiguous upstream-provenance line in the react-router-8 example README. Everything else matching vite* is intentional: upstream BuildEndHook.viteConfig API surface, the UPSTREAM.json renames/provenance maps, and rename documentation. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Leftovers sweep follow-ups: the package-interop API stub gains modifyBundlerChain and isPluginExists (only reached on the RSC path today - same failure class as the onBeforeCreateCompiler break); hdrRevisionModuleContent is de-exported (single in-file consumer). tsc --noUnusedLocals verified zero unused imports; mode-plan/ entry-paths type exports stay - declaration emit requires them for exported function signatures. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

- requestSingleFetchData now re-keys decoded SingleFetchRedirect entries onto the harness react-router's symbol instance - the fixture (RR 8.1) and harness (RR 7.18) each own a distinct Symbol('SingleFetchRedirect'), so equality assertions could never match (6 failures) - SPA-mode preview serves build/client statically with an index.html fallback (extension-ful misses 404 so networkidle settles) instead of invoking react-router-serve on a server bundle SPA builds don't have - the 'Custom dev servers need an Rsbuild dev-server adapter' placeholders are replaced with a real adapter (createRsbuild -> createDevServer -> express app.use(devServer.middlewares)), which the plugin's classic AND rsc dev handlers both attach to - covers 9 of 10 custom-server cases; loader-context keeps an accurate throw (needs a plugin-side load-context entry, out of harness scope) RSC bundler-mode fixtures (rsc-test/rsc-nojs, 4 failures) are NOT converted: they target unstable_RSCRouteConfig bundler mode while the adapter generates framework-mode configs - a fixture mode-migration tracked separately, not a rename. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…l, splat warning, prerender root loader Salvaged from credit-interrupted agents (quick-wins batch + workflow prerender feature), verified via unit suite: - dev/browser manifest no longer lists a route's own module inside route.imports (duplicate modulepreload hrefs) - route-config-not-found error names app/routes.ts like upstream instead of the last-probed .tsx extension - entry.client web entry sets html:false so no stray entry.client.html lands in build/client - prerender:true now warns for dynamic/splat paths that cannot be enumerated, matching upstream's message - ssr:false prerender validation exempts the root route's loader the way upstream does (root loader is allowed when prerendering) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Benchmark Results

Compared PR head 1cd7448 against base 94ed3cc.

Reading benchmark confidence

Raw deltas are always shown. The signal label only indicates whether the observed median delta is larger than a robust run-to-run noise band; it does not erase or replace the measurement.

The noise band is the larger of 2% or two combined robust standard deviations estimated from each side's relative median absolute deviation (rMAD). Fewer than three finite samples is reported as insufficient data. An inconclusive result should be rerun or investigated from the uploaded raw samples before drawing a performance conclusion.
