# 2.0.0 (Breaking update)

## Additions

* New `command` input
* This allows you to specify the Wrangler command you would like to run.
For example, if you want to publish the production version of your Worker you may run `publish --env=production`.
* This opens up other possibilities too like publishing a Pages project: `pages publish <directory> --project-name=<name>`.
* New `accountId` input
* This allows you to specify your account ID.

## Removals

* Removed `publish` input (refer to [Breaking changes](#breaking-changes)).

## Changes

-- no changes --

## __Breaking changes__

* `publish` has been removed.
* You should instead do `command: publish`.

# Wrangler GitHub Action

✨ Zero-config [Cloudflare Workers](https://workers.cloudflare.com) deployment using [Wrangler](https://github.com/cloudflare/wrangler) and [GitHub Actions](https://github.com/actions)
Easy-to-use GitHub Action to use [Wrangler](https://developers.cloudflare.com/workers/cli-wrangler/). Makes deploying Workers, Pages or modifying R2 easy to do.

[Refer to Changelog for more information](CHANGELOG.md).

## Usage

Add `wrangler-action` to the workflow for your Workers application. The below example will publish your application on pushes to the `master` branch:

## Configuration

If you're using Wrangler's [environments](https://developers.cloudflare.com/workers/tooling/wrangler/configuration/environments/) feature, you can customize _where_ the action deploys to by passing an `environment` in the `with` block of your workflow:

```yaml
jobs:
deploy:
steps:
uses: cloudflare/wrangler-action@1.3.0
with:
apiToken: ${{ secrets.CF_API_TOKEN }}
environment: 'production'
```

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](https://semver.org/)-style version number, such as `1.6.0`:

```yaml
jobs:
deploy:
steps:

If you need to run additional shell commands before or after `wrangler publish`, you can specify them as input to `preCommands` (before publish) or `postCommands` (after publish). These can include additional `wrangler` commands (i.e. `build`, `kv:key put`) or any other commands available inside the `wrangler-action` context.

Set the optional `publish` input to false to skip publishing your Worker project and secrets. Useful in conjunction with pre and post commands. For example, if you only wanted to run `wrangler build` against your project:
You can use the `command` option to do specific actions such as running `wrangler whoami` against your project:

## Use cases

### Deploying when commits are merged to master
### Deploy when commits are merged to main

The above workflow examples have already shown how to run `wrangler-action` when new commits are merged to the master branch. For most developers, this workflow will easily replace manual deploys and be a great first integration step with `wrangler-action`:

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, check out the [GitHub Actions documentation](https://help.github.com/en/articles/workflow-syntax-for-github-actions#on).

### Deploy your Pages site (production & preview)

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 publish as a preview deployment:

```yaml
on: [push]
jobs:
deploy:
runs-on: ubuntu-latest
name: Deploy
steps:
- uses: actions/checkout@v3
- name: Publish
uses: cloudflare/wrangler-action@2.0.0
with:
apiToken: ${{ secrets.CF_API_TOKEN }}
accountId: ${{ secrets.CF_ACCOUNT_ID }}
command: pages publish --project-name=example
```

### Deploying on a schedule

If you'd like to deploy your Workers application on a recurring basis – for instance, 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:

### Deploying on a "dispatched" event
### Manually triggering a deployment

If you need to trigger a workflow at-will, you can use GitHub's `workflow_dispatch` [event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#workflow_dispatch) in your workflow file. By setting your workflow to trigger on that event, you'll be able to deploy your application via the GitHub UI. The UI also accepts inputs that can be used to configure the action :

## Troubleshooting

This action is in beta, and I'm looking for folks to use it! If something goes wrong, please file an issue! That being said, there's a couple things you should know:

### "I just started using Workers/Wrangler and I don't know what this is!"

No problem! Check out the [Quick Start guide](https://developers.cloudflare.com/workers/quickstart) in our docs 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. That's where this action comes in - nice!

### "I'm trying to deploy my static site but it isn't working!"
### "[ERROR] No account id found, quitting.."

To deploy static sites and frontend applications to Workers, check out the documentation for [Workers Sites](https://developers.cloudflare.com/workers/sites).

Note that this action makes no assumptions about _how_ your project is built! **If you need to run a pre-publish step, like building your application, you need to specify a build step in your Workflow.** For instance, if I have an NPM command called `build`, my workflow YAML might resemble the following:
You will need to add `account_id = ""` in your `wrangler.toml` file or set `accountId` in this GitHub Action.
