script

This action makes it easy to quickly write a script in your workflow that uses the GitHub API and the workflow execution context.

In order to use this action, a script input is provided. The value of that input should be the body of an asynchronous function call. Two arguments will be provided:

• github A pre-authenticated octokit/rest.js client
• context An object containing the context of the workflow run

Since the script is just a function body, these values will already be defined, so you don't have to (see examples below).

See octokit/rest.js for the API client documentation.
