# GitHub Action: Run Clippy with reviewdog
# Create a JavaScript Action using TypeScript
This action runs [Clippy](https://github.com/rust-lang/rust-clippy) with
[reviewdog](https://github.com/reviewdog/reviewdog) on pull requests to improve code review experience.
Use this template to bootstrap the creation of a TypeScript action.:rocket:
## Example usage
This template includes compilation support, tests, a validation workflow, publishing, and versioning guidance.
If you are new, there's also a simpler introduction. See the [Hello World JavaScript Action](https://github.com/actions/hello-world-javascript-action)
## Create an action from this template
Click the `Use this Template` and provide the new repo details for your action
## Code in Main
> First, you'll need to have a reasonably modern version of `node` handy. This won't work with versions older than 9, for instance.
Install the dependencies
```bash
$ npm install
```
Build the typescript and package it for distribution
```bash
$ npm run build && npm run package
```
Run the tests :heavy_check_mark:
```bash
$ npm test
PASS ./index.test.js
✓ throws invalid number (3ms)
✓ wait 500 ms (504ms)
✓ test runs (95ms)
...
```
## Change action.yml
The action.yml defines the inputs and output for your action.
Update the action.yml with your name, description, inputs and outputs for your action.
See the [documentation](https://help.github.com/en/articles/metadata-syntax-for-github-actions)
## Change the Code
Most toolkit and CI/CD operations involve async operations so the action is run in an async function.
```javascript
import * as core from '@actions/core';
...
async function run() {
try {
...
}
catch (error) {
core.setFailed(error.message);
}
}
run()
```
See the [toolkit documentation](https://github.com/actions/toolkit/blob/master/README.md#packages) for the various packages.
## Publish to a distribution branch
Actions are run from GitHub repos so we will checkin the packed dist folder.
Then run [ncc](https://github.com/zeit/ncc) and push the results:
```bash
$ npm run package
$ git add dist
$ git commit -a -m "prod dependencies"
$ git push origin releases/v1
```
Note: We recommend using the `--license` option for ncc, which will create a license file for all of the production node modules used in your project.
Your action is now published! :rocket:
See the [versioning documentation](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
## Validate
You can now validate the action by referencing `./` in a workflow in your repo (see [test.yml](.github/workflows/test.yml))
```yaml
uses: ./
```yml
name: clippy-action
on: [pull_request]
env:
CARGO_TERM_COLOR: always
jobs:
clippy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Install latest nightly
uses: actions-rs/toolchain@v1
with:
milliseconds: 1000
toolchain: nightly
override: true
components: rustfmt, clippy
- name: clippy-action
uses: giraffate/clippy-action@main
with:
reporter: 'github-pr-review'
github_token: ${{ secrets.GITHUB_TOKEN }}
```
See the [actions tab](https://github.com/actions/typescript-action/actions) for runs of this action! :rocket:
