Until recently, Angular used Webpack to build applications. Based on this, some third-party builders emerged to allow users to use a custom Webpack configuration when building their Angular applications. When Angular switched to Esbuild, this meant that it became difficult for applications that used custom Webpack configurations to migrate to the new build system. This guide will help you migrate from Angular with Webpack to Rspack. By migrating to Rspack, you can gain an immediate build performance benefit while maintaining the your existing Webpack build toolchain.
Step 1: Initialize Nx
Section titled “Step 1: Initialize Nx”Nx provides a generator to convert existing Angular Webpack projects to use @nx/angular-rspack. This generator is currently available in Nx 20.6.0.
At the root of your project, run the following command:
npx nx@latest initStep 2: Run the Convert to Rspack Generator
Section titled “Step 2: Run the Convert to Rspack Generator”With Nx now initialized, the @nx/angular plugin will have been installed providing access to a series of generators and executors that aid Angular development. In particular, the @nx/angular:convert-to-rspack generator will convert an Angular project to use Rspack. To use it, run the following command:
npx nx g convert-to-rspackStep 3: Run your application
Section titled “Step 3: Run your application”After running the generator, you can run tasks such as build and serve to build and serve your application.
npx nx build yourProjectNamenpx nx serve yourProjectName
