Octokit.js is a GitHub API SDK used to interact with GitHub via REST and GraphQL interfaces. It serves as a client for executing typed queries and mutations, managing authenticated REST requests, and handling signed webhooks across Node.js, Deno, and browser environments.
The library features a plugin-based request pipeline and an adapter-based HTTP client, allowing the interception of requests and responses across different runtimes. It employs strategy-based authentication to separate credential management from request logic, supporting static tokens, OAuth flows, and GitHub App installation authentication.
The toolkit covers broad capability areas including automated repository management through asynchronous pagination, webhook event processing via middleware, and the orchestration of OAuth identity flows. It also provides utilities for routing API traffic through custom HTTPS proxies.
