async function main() {
  const octokit = new Octokit({ auth: process.env.ACCESS_TOKEN });
  const changes =

  )
}

reviewPullRequest(options)

The reviewPullRequest() method creates a code suggestion review on a GitHub Pull request with the files given as input. From these files, calculate the hunk diff and make all the multiline code suggestion review comments on a given pull request with these hunks given that they are in scope of the pull request. Outof scope suggestions are not made.

In-scope suggestions are specifically: suggestions whose file is in-scope of the pull request, and suggestions whose diff hunk is a subset of the pull request's files hunks.

If a file is too large to load in the review, it is skipped in the suggestion phase.

If the program terminates without exception, a timeline comment will be made with all errors or suggestions that could not be made.

on:
  push:
    branches:
      - main
name: ci
jobs:
  add-license:
    runs-on: ubuntu-latest
    env:
      ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
    steps:
      - uses: actions/checkout@v2
      - name: <YOUR CHANGES> # the physical changes you want to make to your repository
        run: (curl http://www.apache.org/licenses/LICENSE-2.0.txt) > LICENSE # For example adding LICENSE file
      - uses: googleapis/code-suggester@v2 # takes the changes from git directory
        with:
          command: pr
          upstream_owner: Octocat
          upstream_repo: HelloWorld

on:
  pull_request_target:
    types: [opened, synchronize]
    branches:
      - main
name: ci
jobs:
  review-pr:
    runs-on: ubuntu-latest
    env:

    steps:
      - uses: actions/checkout@v2
        with:
          ref: ${{github.event.pull_request.head.ref}}
          repository: ${{github.event.pull_request.head.repo.full_name}}
      - name: format
        run: go fmt
      - uses: googleapis/code-suggester@v2 # takes the changes from git directory
        with:
          command: review
          pull_number: ${{ github.event.pull_request.number }}
          git_dir: '.'

Important: When using pull_request_target and actions/checkout with the pull request code, make sure that an external developer cannot override the commands run from the pull request.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

Legacy Node.js versions are supported as a best effort:

Legacy versions will not be tested in continuous integration.
Some security patches may not be able to be backported.
Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be in alpha. This means it is still a work-in-progress and under active development. Any release is subject to backwards-incompatible changes at any time.
