GitHub API Rate Limits

When installing tools hosted on GitHub (like gh, node, bun, etc.), mise needs to make API calls to GitHub's releases API. Without authentication, these calls are subject to GitHub's rate limit of 60 requests per hour, which can cause installation failures.

- uses: jdx/mise-action@v2
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    # your other configuration

Note: The action automatically uses ${{ github.token }} as the default, so in most cases you don't need to explicitly provide it. However, if you encounter rate limit errors, make sure the token is being passed correctly.

Alternative Installation

Alternatively, mise is easy to use in GitHub Actions even without this:

jobs:
  build:
    steps:
    - run: |
        curl https://mise.run | sh
        echo "$HOME/.local/share/mise/bin" >> $GITHUB_PATH
        echo "$HOME/.local/share/mise/shims" >> $GITHUB_PATH
