[Rspack] Error with Angular CLI project

[edbzn]

Hey,

I get an error while using Rspack with fresh Angular CLI project:

1. Generate new project & install deps

ng new test-rspack
npm i @rspack/cli @ng-rspack/build

2. Create rspack config

const {createConfig} = require("@ng-rspack/build");

module.exports = createConfig({
  root: __dirname,
  outputPath: "dist/browser",
  name: 'test-rspack',
  main: './src/main.ts',
  index: './src/index.html',
  tsConfig: './tsconfig.app.json',
  styles: ["./src/styles.css"],
  polyfills: ["zone.js"],
  assets: ["./public"],
});

3. Run npx rspack build, it outputs:

node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

SyntaxError: /xxx/test-rspack/src/app/app.routes.ts: Missing initializer in const declaration. (3:19)

Node.js v22.12.0

Note that I don't have the issue with Rsbuild.
