Circle CI React Native Orb
Overview
An orb for building React Native applications. Assumes the usage of Fastlane. By default, it:
- Installs dependencies with yarn and caches them
- Installs gem dependencies (typically for Fastlane) and caches them
- Installs gradle dependencies and caches them
- Runs jest tests via
yarn test:ci, which is expected to leverage junit reporter like so:jest --reporters=default --reporters=jest-junit. This does require jest-junit to be installed as a devDependency. - Decodes an Android keystore from $ANDROID_ENCODED_KEYSTORE and saves to android.keystore for later use. encode with
cat <path-to-keystore-file> | base64 | pbcopy - Override ENV vars with branch-specific ENV vars if they exist. example: API_URL_BETA or BETA_API_URL would override API_URL (use pre_build hook to override this)
- Creates an .env file containing current ENV vars for use by react-native-config and others (use pre_build hook to override this)
Other useful features
- pre_build, build, and post_build hooks to customize your build process
- overridable test_steps for jest
Caveats
- Assumes that Fastlane will inject signing config for Android via gradle properties and uses the encoded keystore mentioned above.
TODO
- Detox config coming soon
