MissionHub CI/CD codecov

MissionHub: See God at work and know you are part of it.

Getting Started

To get started running and building the MissionHub application, you need to have a few things installed

  • Node and Yarn
  • Xcode (for iOS build)
  • Android SDK
  • react-native-cli (Run yarn global add react-native-cli)

Check out the Getting Started guides for iOS/Android based on your OS

Development Environment

You'll need to make sure you have a few plugins in your IDE/Editor. Atom or VSCode are pretty common to be used with React-Native.

Plugins:

  • .editorconfig
  • eslint
  • react (for javascript files with jsx syntax)

You'll also need to create a .env file in your project root directory. The easiest way to do this is to copy .env.production to .env and modify the contents of .env accordingly. This file is ignored by Git so no need to worry about accidentally commititing changes that will impact another developer.

Running the application

For iOS:

  • Run yarn ios
  • Or open the ios/MissionHub.xcworkspace file with Xcode and run the MissionHub scheme on a simulator or connected device

For Android:

  • Make sure you have the Android build-tools installed from the sdk for version 26.0.1 along with all the other steps from the react-native documentation.
  • Connect your android device or emulator and make sure it shows up in your terminal when you run adb devices
  • Run yarn android
  • Note: You can also use Android Studio to run the application instead of the terminal

Debugging

You must run the application in in Dev mode to see logs.

You can use the built in Chrome Debugger for a lot of things by shaking the device and selecting Debug JS Remotely.

You can also install the React Native Debugger to see a lot of detail remotely through that application. It will automatically find your device when you run the app.

You can enable Hot Reloading by shaking the device and enabling it from there.

Building the application

For iOS, you can run change the scheme to a Release version and run the application in Xcode.

For Android, to build to a local device, check that there is a device connected by running adb devices, then you can run yarn run android:build. Make sure you've uninstalled any existing MissionHub application on the device first. This will create the apk at this location: /android/app/build/outputs/apk/app-release.apk

Notes

iOS builds can only be run on a Mac.

About env files

This project has three .env files in two different locations. Their purpose is described here:

Project root directory

These files

  • .env.production - this file has the Production API URL, Production authentication server (TheKey) URL, as well as Production keys for code push. This file is meant to be used with any Release build to the Play Store or App Store.
  • .env.staging - this file has the Staging API URL, Production authentication server (TheKey) URL as well as Staging keys for code push. This file is used by Travis for non master builds to point GraphQL tooling at staging.
  • .env - this file is ignored by Git, but developers should use this file to build and run the project locally. It is recommended to copy and paste one of the .env files listed above to this file name and modify as needed.

iOS directory ({ROOT}/ios

  • .env.default - this file has the variables necessary for FastLane to build iOS Archives and Android APK files. It is completely independent from the root level .env files. It is necessary because FastLane does not detect .env files in a location above the native iOS/Android project root directories, which are sub-root to the overall project root directory.

Automated Deployments

MissionHub uses Travis-CI and Fastlane scripts to automate the build and deployment process. The master iOS and Android FastLane builds files are found here and here respectively.

The master build files are a common set of files that can be used to build most any project. Project specific configurations are stored in .env.default inside the ios/ and android/ directories of this project.

[TODO: define what each configuration parameter means/does]

iOS pre-releases are deployed through TestFlight to iTunesConnect users. This setup allows deployment without waiting for a Beta TestFlight review. If it is desired to deploy to external beta testers, then manual developer effort is required to do that through iTunesConnect. iOS releases are promoted to the App Store "release" by passing the parameter of the build number.

Android pre-releases are deployed to the Play Store internal-test track. This setup allows deployment to a controlled group of internal beta testers. If it is desired to deploy to external beta testers, then manual developer effort is required to promote or deploy builds to the alpha or beta track. Android releases are promoted to the Play Store "release" track by promoting the latest "internal" track build. NOTE! The current automation will only promote builds from the "internal" test track to production and will not account for builds in the alpha/beta tracks. PRs welcomed.

Pre-release builds are completed and deployed to TestFlight and the Play Store "internal" track on any push to the master branch, following this process.

iOS Pre-release

  • [developer] push to master
  • [travis] install yarn, fastlane and other dependencies, extract Facebook SDK (sigh).
  • [travis] run yarn install to add node dependencies
  • [travis] run yarn oneskey to fetch updated localizations from Onesky
  • [travis] invoke [fastlane] fastlane ios beta
  • [fastlane] set project build number to travis build number #important b/c the build number set here will be used later to promote the release build!
  • [fastlane] use match to import and decrypt iOS distribution certificate and provisioning profile to keychain
  • [fastlane] build and sign app archive
  • [fastlane] upload signed app archive to TestFlight
    • NOTE: this step can take 5 minutes to nearly 2 hours to complete b/c of automated iTunesConnect checks that vary in length.
  • [fastlane] commit and push the updated build number to GitHub remote with [skip ci] tag to prevent a travis-ci fork bomb
  • [fastlane] notify the MissionHub - Engineering Slack channel of release

Android Pre-release

  • [developer] push to master
  • [travis] install yarn, fastlane and other dependencies
  • [travis] run yarn install to add node dependencies
  • [travis] run yarn oneskey to fetch updated localizations from Onesky
  • [travis] invoke [fastlane] fastlane android beta
  • [fastlane] set project build number to total number of git commits in master branch
  • [fastlane] decrypt Play Store upload key for MH
  • [fastlane] build and sign app APK
  • [fastlane] upload signed app archive to Play Store "internal" test track
  • [fastlane] notify the MissionHub - Engineering Slack channel of release

Production releases for both apps use a standard semantic versioning scheme for version number/name (iOS/Android). [major].[minor].[patch] . In the examples below vx.y.z will refer to a version x.y.z using this scheme.

Travis will build production releases for both platform when it detects a commit in the vx.y.z format where x, y and z can be any number of digits.

Production releases (both platforms)

  • [developer/qa] verify that latest builds work as expected against production!
  • [developer] checkout locally master commit to be deployed
    • NOTE: this should typically be a [skip ci] Bump Build number commit, but not always
  • [developer] create branch releases/vx.y.z
    • NOTE: this the branch name is convention, but travis doesn't care what it is. only the format of the tag matters. the point of creating the branch is to get off master so that when pushing the tag it doesn't also trigger a beta build.
  • [developer] if the most recent commit is a [skip ci] Bump Build number commit, then amend the commit message to drop [skip ci] and note that this is a release commit.
  • [developer] add tag vx.y.z to this commit.
  • [developer] push branch and tags to GH (e.g. git push origin releases/v4.1.1 --tags)
  • [travis] install fastlane and other dependencies in iOS directory
  • [travis] invoke [fastlane] fastlane ios release
  • [fastlane] promote build to iTunesConnect release from TestFlight based on the build number set on the project at this commit.
    • NOTE: this may not be the latest build depending up where the tag and commit are in the Git history!
  • [fastlane] increment patch version number and push to GitHub remote
    • NOTE | [TODO]: this step is skipped right now because the wrong branch is checked out and Travis w/ it's shallow clone won't be able to push back to the remote. PR welcomed.
  • [fastlane] notify the MissionHub - Engineering Slack channel of release
  • [travis] install fastlane and other dependencies in android directory
  • [travis] invoke [fastlane] fastlane android release
  • [fastlane] promote build to Play Store release track from internal track.
    • NOTE: unlike iOS, this will ALWAYS be the latest APK uploaded to "internal" track. anything in the alpha or beta track is ignored
  • [fastlane] notify the MissionHub - Engineering Slack channel of release
  • [developer] soon after, merge master down into develop (no PR required)
  • [developer] set, commit and push to develop the android version name (and iOS version number while this automated step is not working) to next desired value x.y.z+1

Production releases (specific platform)

It is possible, although untested, to release only one platform to only one platform by pushing a tag in the vx.y.z format and appending -ios or -android to build for only iOS or Android respectively. Again create a branch for this from master following the convention releases/vx.y.z-android to avoid needlessly building another pre-release from master when pushing the tag.

Known issues in the automated deployment process

  • The iOS AppStore release TravisCI job will fail if release notes are not added for all languages on appstoreconnect.com . The signed build will be set on the release on AppStore connect, but the release cannot be submitted for review until release notes are added.
  • iOS AppStore TravisCI jobs will sometimes fail for mysterious reasons. The first step, naturally, is to search Stack Overflow and/or FastLane's GitHub issues to see if others are experiencing the same problems. Apple lets FastLane integrate with semi-public APIs, but seems to freely change them w/o warning. The result is that FastLane needs to update their scripts, which usually happens quickly.
    • Locally check out the repo, use bundler to update to the latest FastLane version, push to Travis.
  • Getting Android jobs to accept all of the right releases for SDK and build-tools versions is pretty hairy and a lot of guess work. MH ReactNative had to accept 3 or 4 different versions b/c some dependency somewhere targeted a specific version. sigh
