Octoherd allows you to run a script against multiple repositories in parallel.

A script is a JavaScript function that receives

1. A pre-authenticated octokit instance
2. A repository object
3. An options object with script-specific options

Source code for the hello world Octoherd script

/**
 * The "Hello, World!" of all Octoherd Scripts!
 *
 * @param {import('@octoherd/cli').Octokit} octokit
 * @param {import('@octoherd/cli').Repository} repository
 * @param {object} options
 * @param {string} [options.greetingName] name to be greeted
 */
export async function script(octokit, repository, { greetingName = "World" }) {
  octokit.log.info("Hello, %s! From %s", greetingName, repository.full_name);
}

Run the hello world script with

npx @octoherd/script-hello-world \
  --octoherd-token 0123456789012345678901234567890123456789 \
  "octoherd/*"

For existing scripts, check out repositories with the octoherd-script label.

To create your own script, run

npm init octoherd-script

and follow the instructions. See octoherd/create-octoherd-script for more information.

It's a great time to get involved, look out for "pull request welcome" issues.
