From 21f6ca4440eca746bb79c39a8118dfe5bb7dda6b Mon Sep 17 00:00:00 2001 From: LongYinan Date: Thu, 5 Mar 2026 10:04:33 +0800 Subject: [PATCH 1/2] feat: add SSR manifest plugin for AngularNodeAppEngine support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a Vite plugin that generates the Angular SSR manifests required by AngularNodeAppEngine, which previously threw "Angular app engine manifest is not set" because the OXC Vite plugin did not produce them. Changes: - New `angular-ssr-manifest-plugin.ts`: detects SSR builds and injects `ɵsetAngularAppManifest` and `ɵsetAngularAppEngineManifest` into files that reference AngularNodeAppEngine/AngularAppEngine - Add `ssrEntry` option to PluginOptions for specifying main.server.ts - Fix `ngServerMode` define to also be set during dev SSR builds - Add unit tests (vitest) and e2e tests (Playwright) for manifest generation Co-Authored-By: Claude Opus 4.6 --- .../e2e/tests/ssr-manifest.spec.ts | 192 ++++++++++++++++++ .../test/ssr-manifest.test.ts | 113 +++++++++++ .../angular-build-optimizer-plugin.ts | 18 +- .../angular-ssr-manifest-plugin.ts | 190 +++++++++++++++++ napi/angular-compiler/vite-plugin/index.ts | 7 + 5 files changed, 518 insertions(+), 2 deletions(-) create mode 100644 napi/angular-compiler/e2e/tests/ssr-manifest.spec.ts create mode 100644 napi/angular-compiler/test/ssr-manifest.test.ts create mode 100644 napi/angular-compiler/vite-plugin/angular-ssr-manifest-plugin.ts diff --git a/napi/angular-compiler/e2e/tests/ssr-manifest.spec.ts b/napi/angular-compiler/e2e/tests/ssr-manifest.spec.ts new file mode 100644 index 000000000..3fb429013 --- /dev/null +++ b/napi/angular-compiler/e2e/tests/ssr-manifest.spec.ts @@ -0,0 +1,192 @@ +/** + * SSR Manifest e2e tests. + * + * Verifies that the Vite plugin injects Angular SSR manifests into SSR builds. + * Without these manifests, AngularNodeAppEngine throws: + * "Angular app engine manifest is not set." + * + * @see https://github.com/voidzero-dev/oxc-angular-compiler/issues/60 + */ +import { execSync } from 'node:child_process' +import { existsSync, mkdirSync, readFileSync, rmSync, writeFileSync } from 'node:fs' +import { join } from 'node:path' +import { fileURLToPath } from 'node:url' + +import { test, expect } from '@playwright/test' + +const __dirname = fileURLToPath(new URL('.', import.meta.url)) +const APP_DIR = join(__dirname, '../app') +const SSR_OUT_DIR = join(APP_DIR, 'dist-ssr') + +/** + * Helper: write a temporary file in the e2e app and track it for cleanup. + */ +const tempFiles: string[] = [] + +function writeTempFile(relativePath: string, content: string): void { + const fullPath = join(APP_DIR, relativePath) + const dir = join(fullPath, '..') + if (!existsSync(dir)) { + mkdirSync(dir, { recursive: true }) + } + writeFileSync(fullPath, content, 'utf-8') + tempFiles.push(fullPath) +} + +function cleanup(): void { + for (const f of tempFiles) { + try { + rmSync(f, { force: true }) + } catch { + // ignore + } + } + tempFiles.length = 0 + try { + rmSync(SSR_OUT_DIR, { recursive: true, force: true }) + } catch { + // ignore + } +} + +test.describe('SSR Manifest Generation (Issue #60)', () => { + test.afterAll(() => { + cleanup() + }) + + test.beforeAll(() => { + cleanup() + + // Create minimal SSR files in the e2e app + writeTempFile( + 'src/main.server.ts', + ` +import { bootstrapApplication } from '@angular/platform-browser';
