checkout/README.md

Checkout

This action checks out your repository to $GITHUB_WORKSPACE, so that your workflow can access the contents of your repository.

By default, this is equivalent to running git fetch and git checkout $GITHUB_SHA, so that you'll always have your repo contents at the version that triggered the workflow. See here to learn what $GITHUB_SHA is for different kinds of events.

Usage

See action.yml

Basic:

steps:
- uses: actions/checkout@v1
- uses: actions/setup-node@v1
  with:
    node-version: 10.x 
- run: npm install
- run: npm test

By default, the branch or tag ref that triggered the workflow will be checked out, ${{ github.token }} will be used for any Git server authentication. If you wish to check out a different branch, a different repository or use different token to checkout, specify that using with.ref, with.repository and with.token:

Checkout different branch from the workflow repository:

- uses: actions/checkout@v1
  with:
    ref: some-branch

Checkout different private repository:

- uses: actions/checkout@v1
  with:
    repository: myAccount/myRepository
    ref: refs/heads/release
    token: ${{ secrets.GitHub_PAT }} // `GitHub_PAT` is a secret contains your PAT.

Checkout private submodules:

- uses: actions/checkout@v1
  with:
    submodules: recursive
    token: ${{ secrets.GitHub_PAT }} // `GitHub_PAT` is a secret contains your PAT.

• with.token will be used as Basic authentication header for https requests talk to https://github.com from git(.exe), ensure those private submodules are configured via https not ssh.
• ${{ github.token }} only has permission to the workflow triggering repository. If the repository contains any submodules that comes from private repository, you will have to add your PAT as secret and use the secret in with.token to make checkout action work.

For more details, see Contexts and expression syntax for GitHub Actions and Creating and using secrets (encrypted variables)
