Easy-to-use GitHub Action to use Wrangler. Makes deploying Workers a breeze.
- Wrangler v1 is no longer supported.
- Global API key & Email Auth no longer supported
- Action version syntax is newly supported. This means e.g.
uses: cloudflare/wrangler-action@v3,uses: cloudflare/[email protected], anduses: cloudflare/[email protected]are all now valid syntax. Previously supported syntax e.g.uses: cloudflare/[email protected]is no longer supported -- the prefixvis now necessary.
Refer to Changelog for more information.
Add wrangler-action to the workflow for your Workers/Pages application. The below example will deploy a Worker on a git push to the main branch:
name: Deploy
on:
push:
branches:
- main
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Deploy
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API token (for help finding this, see the Workers documentation). Your API token is encrypted by GitHub, and the action won't print it into logs, so it should be safe!
With your API token set as a secret for your repository, pass it to the action in the with block of your workflow. Below, I've set the secret name to CLOUDFLARE_API_TOKEN:
jobs:
deploy:
name: Deploy
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}If you need to install a specific version of Wrangler to use for deployment, you can also pass the input wranglerVersion to install a specific version of Wrangler from NPM. This should be a SemVer-style version number, such as 2.20.0:
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
wranglerVersion: "2.20.0"Optionally, you can also pass a workingDirectory key to the action. This will allow you to specify a subdirectory of the repo to run the Wrangler command from.
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
workingDirectory: "subfoldername"Worker secrets can optionally be passed in via secrets as a string of names separated by newlines. Each secret name must match the name of an environment variable specified in the env field. This creates or replaces the value for the Worker secret using the wrangler secret put command.
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
secrets: |
SECRET1
SECRET2
env:
SECRET1: ${{ secrets.SECRET1 }}
SECRET2: ${{ secrets.SECRET2 }}If you need to run additional shell commands before or after your command, you can specify them as input to preCommands (before deploy) or postCommands (after deploy). These can include additional wrangler commands (that is, whoami, kv:key put) or any other commands available inside the wrangler-action context.
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
preCommands: echo "*** pre command ***"
postCommands: |
echo "*** post commands ***"
wrangler kv:key put --binding=MY_KV key2 value2
echo "******"You can use the command option to do specific actions such as running wrangler whoami against your project:
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
command: whoamiThe above workflow examples have already shown how to run wrangler-action when new commits are merged to the main branch. For most developers, this workflow will easily replace manual deploys and be a great first integration step with wrangler-action:
on:
push:
branches:
- main
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Deploy
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}Note that there are a number of possible events, like push, that can be used to trigger a workflow. For more details on the events available, refer to the GitHub Actions documentation.
If you want to deploy your Pages project with GitHub Actions rather than the built-in continous integration (CI), then this is a great way to do it. Wrangler 2 will populate the commit message and branch for you. You only need to pass the project name. If a push to a non-production branch is done, it will deploy as a preview deployment:
on: [push]
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Deploy
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
command: pages deploy YOUR_DIST_FOLDER --project-name=exampleIf you would like to deploy your Workers application on a recurring basis – for example, every hour, or daily – the schedule trigger allows you to use cron syntax to define a workflow schedule. The below example will deploy at the beginning of every hour:
on:
schedule:
- cron: "0 * * * *"
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Deploy app
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}If you need help defining the correct cron syntax, check out crontab.guru, which provides a friendly user interface for validating your cron schedule.
If you need to trigger a workflow at-will, you can use GitHub's workflow_dispatch event in your workflow file. By setting your workflow to trigger on that event, you will be able to deploy your application via the GitHub UI. The UI also accepts inputs that can be used to configure the action:
on:
workflow_dispatch:
inputs:
environment:
description: "Choose an environment to deploy to: <dev|staging|prod>"
required: true
default: "dev"
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Deploy app
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
command: deploy --env ${{ github.event.inputs.environment }}For more advanced usage or to programmatically trigger the workflow from scripts, refer to the GitHub documentation for making API calls.
To create a new version of your Worker that is not deployed immediately, use the wrangler versions upload --experimental-versions command. Worker versions created in this way can then be deployed all at once at a later time or gradually deployed using the wranger versions deploy --experimental-versions command or via the Cloudflare dashboard under the Deployments tab. For now, the --experimental-versions flag and wrangler v3.40.0 or above is required to use this feature.
jobs:
upload:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v4
- name: Upload Worker Version
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
command: versions upload --experimental-versionsMore advanced workflows may need to parse the resulting output of Wrangler commands. To do this, you can use the command-output output variable in subsequent steps. For example, if you want to print the output of the Wrangler command, you can do the following:
- name: Deploy
id: deploy
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
command: pages deploy --project-name=example
- name: print wrangler command output
env:
CMD_OUTPUT: ${{ steps.deploy.outputs.command-output }}
run: echo $CMD_OUTPUTNow when you run your workflow, you will see the full output of the Wrangler command in your workflow logs. You can also use this output in subsequent workflow steps to parse the output for specific values.
Note: the
command-stderroutput variable is also available if you need to parse the standard error output of the Wrangler command.
If you are executing a Wrangler command that results in either a Workers or Pages deployment, you can utilize the deployment-url output variable to get the URL of the deployment. For example, if you want to print the deployment URL after deploying your application, you can do the following:
- name: Deploy
id: deploy
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
command: pages deploy --project-name=example
- name: print deployment-url
env:
DEPLOYMENT_URL: ${{ steps.deploy.outputs.deployment-url }}
run: echo $DEPLOYMENT_URLThe resulting output will look something like this:
https://<your_pages_site>.pages.dev
By default, this action will detect which package manager to use, based on the presence of a package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb file.
If you need to use a specific package manager for your application, you can set the packageManager input to npm, yarn, pnpm, or bun. You don't need to set this option unless you want to override the default behavior.
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
packageManager: pnpmRefer to the Quick Start guide to get started. Once you have a Workers application, you may want to set it up to automatically deploy from GitHub whenever you change your project.
You will need to add account_id = "" in your wrangler.toml file or set accountId in this GitHub Action.
