Contributing to React Native WebView

First off, thank you for considering contributing to the React Native Community. The community-supported packages are only possible because of amazing people like you.

Secondly, we'd like the contribution experience to be as good as possible. While we are a small all-volunteer team, we are happy to hear feedback about your experience, and if we can make the docs or experience better please let us know.

How to test changes

After you fork the repo, clone it to your machine, and make your changes, you'll want to test them in an app.

In a new react-native init project, do this:

$ yarn add ../react-native-webview
$ react-native link react-native-webview

You may run into a problem where the jest-haste-map module map says react-native was added twice:

Loading dependency graph...(node:32651) UnhandledPromiseRejectionWarning: Error: jest-haste-map: Haste module naming collision:
  Duplicate module name: react-native
  Paths: /Users/myuser/TestApp/node_modules/react-native/package.json collides with /Users/myuser/TestApp/node_modules/react-native-webview/node_modules/react-native/package.json

Just remove the second path like this:

$ rm -rf ./node_modules/react-native-webview/node_modules/react-native

And then re-run the packager:

$ react-native start --reset-cache

When you make a change, you'll probably need to unlink, remove, re-add, and re-link react-native-webview:

$ react-native unlink react-native-webview && yarn remove react-native-webview
$ yarn add ../react-native-webview && react-native link react-native-webview

Notes

  • We use TypeScript.
  • After pulling this repo and installing all dependencies, you can run tests using the command: yarn ci
