Publish, build or manage your Expo app with GitHub Actions!
Usage — Examples — Caveats — Changelog
With this Expo action, you have full access to Expo CLI and EAS CLI.
It lets you automate the eas update or eas build commands, leaving you with more time to work on your project.
Some additional features are included to make the usage of this action as simple as possible, like caching and authentication.
Create your
EXPO_TOKENGitHub secret.
This action is customizable through variables defined in the action.yml.
Here is a summary of all the input options you can use.

| expo-version | - | Expo CLI version to install (skips when omitted) |
| expo-cache | true |

Before diving into the workflow examples, you should know the basics of GitHub Actions. You can read more about this in the GitHub Actions documentation.
This workflow listens to the push event on the main branch.
It sets up all required components to publish the app, including authentication with a token.
Always use secrets when using tokens.

run: eas update --auto --non-interactiveThis action also allows you to install the EAS CLI.
To do this, add the eas-version property, and the action will install it.
We recommend using latest for the EAS CLI.
The token is shared for both Expo and EAS CLI.

# `github.event.pull_request.head.ref` is only available on `pull_request` triggers.
# Use your own, or keep the automatically infered branch name from `--auto`, when using different triggers.
command: eas update --auto --branch ${{ github.event.pull_request.head.ref }}Some Expo commands, like expo publish and eas build, require you to be authenticated.
This action exports the token to ensure you are authenticated in every workflow step.
Note, this action does not store the token anywhere. Each separate workflow job needs to set up the token individually.
You can opt-out from caching the Expo and EAS CLI installations.
Under the hood, it uses the @actions/cache package to restore a previous install.
It reduces the installation time because it only needs to download and extract a single tar file.
Note, using cache will count towards your repo cache limit. Both the Expo and EAS CLI are stored in different caches.
Creating new bundles with Metro can be memory intensive.
In the past, some builds resulted in ENOSPC errors.
To prevent anyone from running into this, we make sure Ubuntu has sensible defaults in terms of file system availability.
You can opt-out from patching the file system by setting patch-watchers to false.
