I have made CLI for create expo library.
https://www.npmjs.com/package/expo-library

Alt Text

Install globally

This package requires node >= 10.

install expo-library by

npm install -g expo-library

Creating a New Library

expo-library

Answer some basic prompts about your module, and then the CLI will perform the following steps:

  • copy over the template
  • install dependencies via yarn or npm
  • link packages together for local development
  • initialize local git repo

Development

Local development is broken into two parts (ideally using two tabs).

First, go to root dir of newly create library and edit component in index.js/ts file.

Second, go to example/ dir and run metro bundle by

cd example
npm start # runs your expo app bundler

Now, anytime you make a change to your library in index.js or to the example app's example/App.js will fresh refresh component in example.

Publishing to npm

npm publish

Make sure that any npm modules you want as peer dependencies are properly marked as peerDependencies in package.json.
