 We recommend using lightweight libraries in your project, such as replacing [moment](https://momentjs.com/) with [day.js](https://day.js.org/).
 
-To identify large libraries in your project, add the `BUNDLE_ANALYZE=true` environment variable when building:
-
-```bash
-BUNDLE_ANALYZE=true pnpm build
-```
-
-See the [performance.bundleAnalyze](/config/performance/bundle-analyze) configuration for details.
