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
