RSC server plugin correctly identifies 'use server' modules + - Assigns moduleIds via chunkGraph + - Writes server-references-manifest.json + - AST-based fallback ensures moduleId discovery even with timing issues + +2. **Manifest Hydration** ✅ + - Done hook hydrates moduleIds from chunkGraph + - Reads back manifest file with 100ms delay + - Client loader retries with configurable attempts and delay + - Falls back to manifest file if sharedData unavailable + +3. **Remote Builds** ✅ + - Both CSR and SSR remotes build successfully + - MF exposures work correctly + - Server actions (action.ts) properly registered + +4. **Host Builds** ✅ + - Both CSR and SSR hosts build successfully + - Empty manifests are expected (no local components) + - MF configuration properly set up for consuming remotes + +5. **TypeScript Compilation** ✅ + - All type errors resolved + - ServerReferencesModuleInfo type properly respected + - Immutable property constraints followed + +### Key Findings + +1. **Candidates Mechanism Timing Issue** + - `serverModuleInfoCandidates` relies on web compiler discovering modules before server compiler finishes + - In practice, server compiler's finishMake hook runs before web compiler's module transformations + - Candidates Map is empty (size 0) when server plugin tries to merge + - This mechanism cannot work reliably for modules only in web graph + +2. **Working Pattern: Explicit Server Graph Inclusion** + - CSR remote works because App.tsx imports `./rsc-server-refs.ts` + - rsc-server-refs.ts explicitly imports server action modules + - This ensures action.ts is in server compiler's graph and gets moduleId assigned + - SSR remote fixed by adding same pattern + +3. **Host Manifest Behavior** + - Hosts with no local client components or server actions correctly have empty manifests + - The entry-server rule applies to host entries but they don't import local components + - Hosts consume components from remotes at runtime + - Empty manifests don't prevent builds or runtime consumption + +## Commits Made + +1. **6bed533**: Initial RSC+MF integration (77 files) +2. **9f8ad313a**: Fixed TypeScript type errors and plugin registration +3. **eb10b34aa**: Fixed SWC parser error +4. **f4cb50393**: Fixed HtmlWebpackPlugin child compiler crashes +5. **68902ccfc**: Integration improvements (auto-generated) +6. **69a14df88**: Added manifest hydration for server module IDs +7. **d936d674c**: Added integration status documentation +8. **d59d01a16**: (User) Treat app entries as react-server layer roots +9. **26a789835**: (User) AST-based export derivation + increased retries + +## Next Steps to Complete Integration + +### Immediate Priority: Run Integration Tests + +1. **Test CSR Host + Remote**: + ```bash + cd tests + pnpm exec jest --testPathPattern=rsc-csr-mf-host --runInBand --no-coverage --forceExit + ``` + -

The RSC+MF integration itself is functional - manifests generate, merge, and server references are discovered correctly. diff --git a/package.json b/package.json index 8b564b91568a..a7e3defd5a0e 100644 --- a/package.json +++ b/package.json @@ -48,7 +48,8 @@ "build:main_docs": "pnpm --filter @modern-js/main-doc... build && pnpm --filter @modern-js/main-doc build", "build:module_docs": "pnpm --filter @modern-js/module-tools-docs... build && pnpm --filter @modern-js/module-tools-docs build", "gen:docs": "rm -rf doc_output && mkdir doc_output && cp -r ./packages/document/main-doc/doc_build/* ./doc_output && cp -r ./packages/document/module-doc/doc_build/ ./doc_output/module-tools", - "build:docs": "pnpm run build:main_docs && pnpm run build:module_docs && pnpm run gen:docs" + "build:docs": "pnpm run build:main_docs && pnpm run build:module_docs && pnpm run gen:docs", + "demo:rsc:mf:csr": "BUNDLER=webpack pnpm -C tests/integration/rsc-csr-mf build && BUNDLER=webpack pnpm -C tests/integration/rsc-csr-mf-host build && (PORT=3001 NODE_ENV=production ASSET_PREFIX=http://localhost:3001 MODERN_MF_AUTO_CORS=1 pnpm -C tests/integration/rsc-csr-mf serve &) && sleep 5 && PORT=3000 NODE_ENV=production ASSET_PREFIX=http://localhost:3001 pnpm -C tests/integration/rsc-csr-mf-host serve" }, "engines": { "node": ">=18", @@ -112,5 +113,8 @@ "uuid": "3.4.0", "trim": "0.0.1" } + }, + "dependencies": { + "@module-federation/node": "2.7.19" } } diff --git a/packages/cli/uni-builder/src/shared/rsc/plugins/rsbuild-rsc-plugin.ts b/packages/cli/uni-builder/src/shared/rsc/plugins/rsbuild-rsc-plugin.ts index 35087014d4e9..69041849b328 100644 --- a/packages/cli/uni-builder/src/shared/rsc/plugins/rsbuild-rsc-plugin.ts +++ b/packages/cli/uni-builder/src/shared/rsc/plugins/rsbuild-rsc-plugin.ts @@ -58,6 +58,29 @@ export const rsbuildRscPlugin = ({ setup(api) { api.modifyBundlerChain({ handler: async (chain, { isServer, CHAIN_ID }) => { + // Guardrail: Rspack does not support Module Federation + RSC right now. + // If a module-federation config is present in the app and the bundler + // is Rspack, exit early with a clear message so users switch to webpack. + if (isRspack) { + const mfConfigCandidates = [ + 'module-federation.config.ts', + 'module-federation.config.js', + 'module-federation.config.mjs', + 'module-federation.config.cjs', + ]; + const hasMfConfig = mfConfigCandidates.some(file => + fse.pathExistsSync(path.resolve(appDir, file)), + ); + if (hasMfConfig) { + logger.error( + '\nModule Federation + React Server Components is not supported with Rspack.\n' + + 'Please build these projects with webpack instead.\n' + + 'Try: `BUNDLER=webpack pnpm run build` or update your package.json scripts.\n', + ); + process.exit(1); + } + } + if (!(await checkReactVersionAtLeast19(appDir))) { logger.error( 'Enable react server component, please make sure the react and react-dom versions are greater than or equal to 19.0.0', @@ -97,6 +120,30 @@ export const rsbuildRscPlugin = ({ appDir, runtimePath: rscServerRuntimePath, internalDirectory, + isServer: true, + }) + .end() + .use(JSRule) + .loader(jsLoaderPath) + .options(jsLoaderOptions) + .end() + .end() + // Fallback detection for host apps with wrapped entries: scan + // src for 'use client' modules even if their issuer isn't in the + // react-server layer, so the server plugin can record them. + .oneOf('rsc-client-detect') + .include.add(/[/\\]src[/\\]/) + .end() + .exclude.add(/node_modules/) + .end() + .use('rsc-server-loader') + .loader(require.resolve('../rsc-server-loader')) + .options({ + entryPath2Name, + appDir, + runtimePath: rscServerRuntimePath, + internalDirectory, + isServer: true, }) .end() .use(JSRule) @@ -132,6 +179,7 @@ export const rsbuildRscPlugin = ({ `${internalDirectory!.replace(/[/\\]/g, '[/\\\\]')}[/\\\\][^/\\\\]*[/\\\\]routes`, ); + // Assign RSC layer to internal framework files (non-MF apps) chain.module .rule('server-module') .resource([ @@ -142,6 +190,9 @@ export const rsbuildRscPlugin = ({ .layer(webpackRscLayerName) .end(); + // Key: Use issuerLayer to assign react-server layer to modules + // imported BY code already in the react-server layer.
