Convert a Create React App project to a Modular Project

To convert an existing Create React App project into a Modular app, start by creating a new Modular project as shown in the getting started documentation:

yarn create modular-react-app my-new-modular-project

Once created:

• Replace the source code within the app workspace inside the packages/ directory with your React app source content.
• Copy the dependencies from the old root package.json to the new Modular one within the app workspace.
  • Ensure the React version and other dependencies in the root Modular package.json are the same as those used in the React app.
• Copy over any necessary custom configurations, and ensure modular start test and build scripts succesfully start, test and build your app.

Your app will now be a Modular app package. You can change the package type in the package’s package.json modular.type field to view if more appropriate.

Feel free to rename the workspace by following this guide: Rename Package.
