extractTranslations

Entry point for the app (default: 'src/index.tsx')

Root directory of the project (default: process.cwd())

Build output directory, relative to rootDir. build writes artefacts here. Bundler-tier output concerns (filename, chunking) are reachable through the bundler escape hatch, not this field.

"dist"

Optional dev-server options (frontend port, HTTPS, public tunnel). CLI flags and env vars override these at run time.

false

Optional backend run alongside the dev server.

When enabled, dev spawns the backend entry under nodemon with TypeScript support, passes SSL certificate paths through to its environment, and ties its lifecycle to the dev server — a backend crash tears the whole process down. Apps without a backend simply omit this field.

Use true (or any backend config, even {}) to run the backend at the default location backend/server.ts; set entry to point elsewhere.

export default defineConfig({
  entry: "./src/index.tsx",
  backend: true, // runs backend/server.ts
});

export default defineConfig({
  entry: "./src/index.tsx",
  backend: { entry: "./api/main.ts", port: 3100 },
});

"backend/server.ts"

3001

false

Optional configuration for extractTranslations.

The bundler to use for building the app. Defaults to 'rsbuild' if not specified.

The only valid value is "rsbuild".

Customize the Rsbuild configuration. Receives the base config and context, returns modified config.

export default defineConfig({
  config: (rsbuildConfig, { mode }) => {
    rsbuildConfig.plugins?.push(myPlugin());
    return rsbuildConfig;
  },
});
