Development workflow

This project is a monorepo managed using Yarn workspaces. It contains the following packages:

  • The library package in the root directory.
  • An example app in the example/ directory.

To get started with the project, run yarn in the root directory to install the required dependencies for each package:

yarn

Since the project relies on Yarn workspaces, you cannot use npm for development.

The example app demonstrates usage of the library. You need to run it to test any changes you make.

It is configured to use the local version of the library, so any changes you make to the library's source code will be reflected in the example app. Changes to the library's JavaScript code will be reflected in the example app without a rebuild, but native code changes will require a rebuild of the example app.

If you want to use Android Studio or XCode to edit the native code, you can open the example/android or example/ios directories respectively in those editors. To edit the Objective-C or Swift files, open example/ios/Auth0Example.xcworkspace in XCode and find the source files at Pods > Development Pods > react-native-auth0.

To edit the Java or Kotlin files, open example/android in Android studio and find the source files at react-native-auth0 under Android.

You can use various commands from the root directory to work with the project.

To start the packager:

yarn example start

To run the example app on Android:

yarn example android

To run the example app on iOS:

yarn example ios

To confirm that the app is running with the new architecture, you can check the Metro logs for a message like this:

Running "Auth0Example" with {"fabric":true,"initialProps":{"concurrentRoot":true},"rootTag":1}

Note the "fabric":true and "concurrentRoot":true properties.

Make sure your code passes TypeScript and ESLint. Run the following to verify:

yarn typecheck
yarn lint

To fix formatting errors, run the following:

yarn lint --fix

Remember to add tests for your change if possible. Run the unit tests by:

yarn test

Scripts

The package.json file contains various scripts for common tasks:

  • yarn: setup project by installing dependencies.
  • yarn typecheck: type-check files with TypeScript.
  • yarn lint: lint files with ESLint.
  • yarn test: run unit tests with Jest.
  • yarn example start: start the Metro server for the example app.
  • yarn example android: run the example app on Android.
  • yarn example ios: run the example app on iOS.

Sending a pull request

When you're sending a pull request:

  • Prefer small pull requests focused on one change.
  • Verify that linters and tests are passing.
  • Review the documentation to make sure it looks good.
  • Follow the pull request template when opening a pull request.
  • For pull requests that change the API or implementation, discuss with maintainers first by opening an issue.
