![]() ![]() Workflows are used to schedule and sequence jobs. Finally, we will run the plain AWS command to sync our built files to the bucket. We then attach the persisted workspace so that we get all the built files from the previous jobs and then use a command aws-cli/setup provided by the aws-cli orb to install aws-cli. In deploy_project job, we specify that this job is to be executed by aws-cli orb using the executor property. One thing to note is how we persist the working directory to the workspace so that the built files are available to the next job. We are just cloning our repository, installing our dependencies and then building the project. There is nothing fancy in build_project job. deploy_project – responsible to upload the built files to S3.Ĭommand: aws s3 sync.build_project – responsible to build the project.Jobs are just a group of steps to be performed. We are going to use aws-cli orb to upload files to S3. Next, we will define the orbs that we will be using in our project. Since we are going to use Orbs, we will pick the version 2.1. The first line should mention the version of CircleCI your config is going to target. Now let’s start writing our configuration. circleci and add a file config.yml (so that the file path be in .circleci/config.yml). In your repository’s root, create a folder named. Under “Access keys (access key ID and secret access key)” tab, click “Create New Access Key”, once created download the key file and keep it safe we will be using it later. With Expo, it's straightforward to setup CI/CD pipeline for React Native apps.Log in to your AWS account and navigate to My Security Credentials page. You can specify which context to use in the workflow like this. staging, production).ĬircleCI contexts allows us to define different environment variables per environment. Environment variablesįor most apps, you need to define environment variables for each release channel (e.g. The only differece from the previous flow is that it publishes to the production channel. When a release tag is created, it will run tests, publish JS bundle to Expo on the production channel, and build native binaries for iOS and Android. If you want to automate uploading native binaries, look at EAS Submit (I haven't tried it yet). ![]() Since most updates can be done through OTA updates, you need to rebuild native binaries only when you change native metadata like the app's name or icon or upgrade Expo SDK. I added the approval process as you don't need to build native binaries every time. apk file from Expo and upload them to TestFlight and Google Play Console for testing. Once the native binary has been built, you can download the. Note that you need an Apple Developer account for iOS builds. When a feature branch is merged to the master branch, it will run tests, publish JS bundle to Expo on the staging channel, and build native binaries for iOS and Android. Once the JS bundle is published to Expo, you can test it with Expo Go app. Key: v2-deps-Ĭommand: npx expo-cli publish -non-interactive -max-workers 1 -release-channel $EXPO_RELEASE_CHANNELĬommand: npx expo build:android -t apk -non-interactive -release-channel $EXPO_RELEASE_CHANNEL -no-waitĬommand: npx expo build:ios -t archive -non-interactive -release-channel $EXPO_RELEASE_CHANNEL -no-wait # the Docker image with Cypress dependenciesĭescription: "Restore cache and install dependencies" ![]() Here's the complete config.yml file for this flow. The Android builds are not included for simplicity. The diagram above describes the overall flow of the CI/CD flow. In this post, I will walk you through how to setup CI/CD flow for Expo React Native using Circle CI. Expo is a great abstraction layer around React Native which makes it a lot easier to setup React Native apps, from accessing native APIs to establishing CI/CD pipelines. ![]()
