lint-changes
A CLI, API, and GitHub Action for running ESLint only on changed files. The GitHub Action also automatically compares the current branch against its base branch.
GitHub Action
Use this GitHub Action in a pull request or push trigger via electrovir/lint-changes@latest
. The action has two inputs:
eslintArgs
: a single string of args to pass to ESLint. example:--config configs/my-eslint.config.js
pastSetupCommand
: the command needed to setup your repo's past state for linting. Defaults to justnpm ci
. example:npm ci && npm run compile
GitHub Action example
name: Lint changes
on:
pull_request:
branches:
- '**'
# this lint script is relatively expensive, so it's a good idea to cancel concurrent runs
concurrency:
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: true
jobs:
lint-changes:
name: Lint Changes
runs-on: ubuntu-latest
steps:
- uses: actions/[email protected]
with:
# Fetch the whole git tree so the action can checkout the base ref.
fetch-depth: 0
- uses: electrovir/lint-changes@latest
with:
# Neither of this inputs are required, these are just examples of how to assign them.
eslintArgs: '--config configs/my-eslint.config.js'
pastSetupCommand: 'npm ci && npm run compile'
CLI
You can use this package via your CLI:
- install via npm:
npm i lint-changes
- run the command:
lint-changes
CLI args
The CLI args are the same as the API args (listed here: http://electrovir.github.io/lint-changes/variables/apiArgsShape.html). Each arg should be prefixed with --
and use =<value>
for assignment. Like this: --checkoutBaseRef=true
or --baseRef=main
.
Any other arguments not expected by this API are passed directly to ESLint.
API
You can use this package programmatically:
install via npm:
npm i lint-changes
use the exposed API:
import {lintChanges} from 'lint-changes'; await lintChanges();
For documentation on the API's inputs, outputs, and other exposed functions, see the full docs here: http://electrovir.github.io/lint-changes/functions/lintChanges.html
