![]() After this, you will have a skeleton with the time-consuming essentials setup but which is very easy to: It is designed to be run on existing project (whether it's a 3 years old project or a fresh react-native init awesomeProject doesn't matter) The resulting deployment pipeline is super customisable This will maximise setup speed, reduce bug surface and ensure up-to-date standards when you create your deployment pipeline. In this tutorial, you will make heavy use of the awesome generator-rn-toolbox. In this tutorial, you won't have to open Xcode nor Android Studio, not even once. You can find such articles with this Google search. Other tutorials do a general presentation that lets you figure out the details or a zoom-in on a particular part of the pipeline or a deep-dive on every component which would take too much time to read and require you to join the bits together to make the deployment pipeline. This tutorial will make your React Native deployment pipeline completely operational in 1 hour for iOS and Android. The full CircleCI config can be viewed here.How is this tutorial different? It's a modus operandi. Hopefully, this helps you to get your automated deployment working. We do this straight away even if the value hasn’t changed as the API requires the key to be updated at least once a week otherwise it will be deleted.Ĭommand: curl -X POST -IL /$CURRENT_SHA Then we update the API with the new value, which comes from an environment variable that CircleCI provides - the commit SHA-1 that the job is running against. More information about this can be found in this document, 'Introduction to environment variables').Įcho "export LAST_BUILD=$LAST_BUILD" > $BASH_ENV We achieve this by adding an export command to $BASH_ENV (this is a special CircleCI variable that references a file that gets loaded in to bash before each step. This value is then stored in an environment variable so that we can access it later. First, we get the current value from the API. There are a few steps in the config file to achieve our requirement. Generating this URL isn’t covered in the CircleCI steps below so you’ll need to do it manually. You then use this URL to retrieve the current value or update it with a new value. The API documentation is the best place to start but basically, you send an HTTP POST request with your chosen key and this will return a URL which contains your key along with a random token to authenticate the requests. If master is still on this commit, nothing has changed and no build is necessary. With this, we’re able to store the SHA-1 hash of the commit that the last build is based on. After a bit of head scratching and searching, I came across - a free API for storing key/value pairs. ![]() Our next requirement needs us to keep track of when the last build was distributed, and be able to check whether anything has changed since then. If you need help creating the cron string, I suggest you look at 'crontab guru'. This gives us an automated build that runs at 6 pm Monday to Friday (we don’t work at the weekends so there’s no point running builds on these days). Our workflow for the nightly QA build is as follows: The first requirement is straightforward in CircleCI because workflows can be triggered on a schedule. With this in mind, we started looking at the tools we’d need. While some developers are able to configure the right settings, others find it confusing so it’s easier to just leave Xcode alone. ![]() Xcode likes you to use its Automatic settings and it can be a pain if you try to fight it. Minimal impact on Xcode manual builds.This means any build that’s pointing at a dev API can’t be uploaded to TestFlight so we use fabric beta these builds. We have an internal policy which says that we only upload releasable builds to TestFlight. We regularly move between projects and there’s no point distributing builds every day for weeks on end when no one’s working on the project. It should just happen at the end of each working day. We set up nightly QA builds for our iOS projects on CircleCI so that we didn’t have to keep creating them manually.Īs with all development agencies, we’re always looking for ways to improve our processes, particularly with manual jobs that can be automated. ![]()
