This action makes it easy to quickly write a script in your workflow that uses the GitHub API and the workflow run 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:
githubA pre-authenticated octokit/rest.js clientcontextAn 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.
Note This action is still a bit of an experiment—the API may change in *future versions. 🙂

})You can use the github object to access the Octokit API. For
instance, github.request

const result = await github.request(diff_url)
console.log(result)This will print the full diff object in the screen; result.data will
contain the actual diff text.
By default, the JSON-encoded return value of the function is set as the "result" in the
output of a github-script step. For some workflows, string encoding is preferred. This option can be set using the
result-encoding input:

with:
github-token: ${{secrets.GITHUB_TOKEN}}
result-encoding: string
script: |
return "I will be string (not JSON) encoded!"
