How do I authenticate a GitHub App with go-github?

You need to use a third-party package like bradleyfalzon/ghinstallation to handle installation tokens, as go-github delegates this complexity. The README provides code examples using ghinstallation with an HTTP client.

Is go-github better than making direct HTTP calls to GitHub's API?

For most integrations, yes, because it handles authentication, rate limiting, and pagination automatically. However, for trivial or one-off requests, direct HTTP calls might be simpler and avoid library overhead.

How can I paginate through all results efficiently?

Use the ListOptions struct with PerPage settings, or leverage the new iterator methods in Go 1.23 like ListIter for automatic pagination. Alternatively, external packages like gofri/go-github-pagination can handle this for you.

Does go-github support GitHub's GraphQL API?

No, it only supports the REST API v3. For GraphQL, the project explicitly recommends using shurcooL/githubv4, as stated in the development section of the README.

What's the best way to mock go-github for unit testing?

The README points to migueleliasweb/go-github-mock for mocking responses, which allows you to simulate API calls without hitting the real GitHub API, ensuring reliable and fast tests.

How do I handle rate limiting errors without hitting limits?

Check for RateLimitError or AbuseRateLimitError types, and use context-based methods like SleepUntilPrimaryRateLimitResetWhenRateLimited to pause until reset. For advanced cases, integrate gofri/go-github-ratelimit middleware.

github — Go Client for GitHub API v3

What is github?

go-github is a Go client library for accessing the GitHub REST API v3. It provides a comprehensive set of methods to interact with GitHub's platform programmatically, handling authentication, rate limiting, pagination, and webhooks. The library abstracts the API's complexity into an idiomatic Go interface, enabling developers to build tools, automation, and integrations with GitHub.

Target Audience

Go developers building applications that need to interact with GitHub's API, such as CI/CD tools, automation scripts, GitHub Apps, or any service that manages repositories, issues, pull requests, or user data.

Value Proposition

Developers choose go-github because it is the de facto standard Go library for GitHub API integration, maintained by Google and widely adopted. It offers full API coverage, robust handling of GitHub-specific concerns like rate limiting and authentication, and a stable, idiomatic Go API that follows semantic versioning.

Go library for accessing the GitHub v3 API

Use Cases

Best For

Building GitHub Apps or integrations in Go
Automating repository management and DevOps workflows
Creating tools that analyze GitHub data or activity
Developing CI/CD pipelines that interact with GitHub
Handling GitHub webhook events in Go services
Managing issues, pull requests, or projects via API

Not Ideal For

Projects requiring GitHub's GraphQL API v4, as go-github is REST-only and explicitly recommends shurcooL/githubv4 for GraphQL needs.
Applications where minimizing third-party dependencies is critical, as even basic GitHub App authentication relies on external packages like ghinstallation.
Teams working in non-Go environments, since this is a language-specific client library.

Pros & Cons

Pros

Comprehensive API Coverage

Provides methods for nearly all GitHub REST API v3 endpoints, logically organized into services, ensuring developers can access almost any GitHub feature programmatically.

Robust Rate Limiting Handling

Includes built-in detection for primary and secondary rate limits, with utilities like automatic retry and bypass via context flags, reducing common integration pain points.

Idiomatic Pagination Support

Offers both page-number and cursor-based pagination, with new iterator patterns in Go 1.23 for seamless consumption of large datasets without manual looping.

Webhook Event Structs

Provides Go structs for almost all GitHub webhook events, along with payload validation functions, simplifying webhook handling in Go services.

Cons

External Auth Dependencies

GitHub App authentication isn't built-in; it requires third-party packages like ghinstallation or go-githubauth, adding setup complexity and potential maintenance overhead.

Verbose Pointer-Based API

Uses pointer fields for all non-repeated structs to distinguish unset values, making the API more verbose and less intuitive compared to simpler zero-value handling.

Tied to API Volatility

Must constantly adapt to GitHub's calendar versioning, which can introduce breaking changes and require frequent library updates, as noted in the versioning policy.
