A happy little GitHub Action that checks your README.md and other markdown for broken links. Uses linkinator under the hood.

With no arguments, this will scan your README.md in the root of the GitHub repository:

on:
  push:
    branches:
      - main
  pull_request:
name: ci
jobs:
  linkinator:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: JustinBeckwith/linkinator-action@v1

Or you can pass many of the same parameters linkinator provides!

on:
  push:
    branches:
      - main
  pull_request:
name: ci
jobs:
  linkinator:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: JustinBeckwith/linkinator-action@v1
        with:
          paths: test/fixtures/test.md
          concurrency: 1
          markdown: true
          linksToSkip: "http://fake.local, http://fake.local/fake"
