GitHub

The github module provides several helper functions to query GitHub, along with the connection information for more advanced usage.

Configuration

The github configuration is automatically detected from the environment and git.

• The GitHub token is read from the GITHUB_TOKEN environment variable. Some queries might work without authentication for public repositories.

GitHub CodeSpaces

In a GitHub CodeSpace, the GITHUB_TOKEN is automatically provisioned.

GitHub Actions

In GitHub Actions, you might need to add permissions to the workspace to access workflow logs and pull requests. You also need to pass the secret.GITHUB_TOKEN to the GenAIScript script run.

genai.yml

permissions:
    contents: read
    actions: read
    pull-requests: read # or write if you plan to create comments
...
    - run: npx --yes genaiscript ...
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        ...

Functions

Issues

You can query issues and issue comments using listIssues and listIssueComments.

const issues = await github.listIssues({ per_page: 5 })
console.log(issues.map((i) => i.title))

// Use issue number!
const issueComments = await github.listIssueComments(issues[0].number)
console.log(issueComments)

Pull Requests

Query pull requests and pull request review comments using listPullRequests and listPullRequestReviewComments.

const prs = await github.listPullRequests({ per_page: 5 })
console.log(prs.map((i) => i.title))

// Use pull request number!
const prcs = await github.listPullRequestReviewComments(prs[0].number)
console.log(prcs.map((i) => i.body))

In GitHub Actions, ensure the pull-request: read permission is granted.

Workflow Runs

Access the log of workflow runs to analyze failures with listWorkflowRuns.

// List runs
const runs = await github.listWorkflowRuns("build.yml", { per_page: 5 })
console.log(runs.map((i) => i.status))

const jobs = await github.listWorkflowJobs(runs[0].id)
// Redacted job log
console.log(jobs[0].content)

In GitHub Actions, grant the actions: read permission.

Search Code

Use searchCode for a code search on the default branch in the same repository.

const res = await github.searchCode("HTMLToText")
console.log(res)

Get File Content

Retrieve file content for a given ref, tag, or commit SHA using getFile.

const pkg = await github.getFile("package.json", "main")
console.log(pkg.content.slice(0, 50) + "...")

Get Repository Content

List files or directories at a path in a remote repository. By default, file contents from a directory are not loaded. Use downloadContent: true.

// Get top-level markdown files
const files = await github.getRepositoryContent("", {
    type: "file",
    glob: "*.md",
    downloadContent: true,
    maxDownloadSize: 2_000,
})

Languages

Query the list of programming languages that GitHub computed for the repository using listRepositoryLanguages.

const languages = await github.listRepositoryLanguages()

Branches

List the branches on the repository using listBranches.

const branches = await github.listBranches()
console.log(branches)

Advanced Use

Utilize octokit to access the full GitHub APIs.

import { Octokit } from "@octokit/core"

const client: Octokit = await github.client()
...

Install octokit in your list of packages:

npm install -D octokit
