@actions/github

A hydrated Octokit client.

Usage

Returns an authenticated Octokit client that follows the machine proxy settings and correctly sets GHES base urls. See https://octokit.github.io/rest.js for the API.

const github = require('@actions/github');
const core = require('@actions/core');

async function run() {
    // This should be a token with access to your repository scoped in as a secret.
    // The YML workflow will need to set myToken with the GitHub Secret Token
    // myToken: ${{ secrets.GITHUB_TOKEN }}
    // https://help.github.com/en/actions/automating-your-workflow-with-github-actions/authenticating-with-the-github_token#about-the-github_token-secret
    const myToken = core.getInput('myToken');

    const octokit = github.getOctokit(myToken)

    // You can also pass in additional options as a second parameter to getOctokit
    // const octokit = github.getOctokit(myToken, {userAgent: "MyActionVersion1"});

    const { data: pullRequest } = await octokit.pulls.get({
        owner: 'octokit',
        repo: 'rest.js',
        pull_number: 123,
        mediaType: {
          format: 'diff'
        }
    });

    console.log(pullRequest);
}

run();

You can also make GraphQL requests. See https://github.com/octokit/graphql.js for the API.

const result = await octokit.graphql(query, variables);

Finally, you can get the context of the current action:

const github = require('@actions/github');

const context = github.context;

const newIssue = await octokit.issues.create({
  ...context.repo,
  title: 'New issue!',
  body: 'Hello Universe!'
});

Webhook payload typescript definitions

The npm module @octokit/webhooks provides type definitions for the response payloads. You can cast the payload to these types for better type information.

First, install the npm module npm install @octokit/webhooks

Then, assert the type based on the eventName

import * as core from '@actions/core'
import * as github from '@actions/github'
import * as Webhooks from '@octokit/webhooks'
if (github.context.eventName === 'push') {
  const pushPayload = github.context.payload as Webhooks.WebhookPayloadPush
  core.info(`The head commit is: ${pushPayload.head}`)
}

Extending the Octokit instance

@octokit/core now supports the plugin architecture. You can extend the GitHub instance using plugins.

For example, using the @octokit/plugin-enterprise-server you can now access enterprise admin apis on GHES instances.

import { GitHub, getOctokitOptions } from '@actions/github/lib/utils'
import { enterpriseServer220Admin } from '@octokit/plugin-enterprise-server'

const octokit = GitHub.plugin(enterpriseServer220Admin)
// or override some of the default values as well 
// const octokit = GitHub.plugin(enterpriseServer220Admin).defaults({userAgent: "MyNewUserAgent"})

const myToken = core.getInput('myToken');
const myOctokit = new octokit(getOctokitOptions(token))
// Create a new user
myOctokit.enterpriseAdmin.createUser({
  login: "testuser",
  email: "testuser@test.com",
});
