Class: GitHubClient

Defined in: packages/github-client/src/client.ts:83

Thin wrapper around Octokit that adds proactive rate-limit checking.

Remarks

This class is intentionally minimal — it exposes the underlying Octokit instance via GitHubClient.getOctokit so callers can use the full Octokit API without re-implementing every method.

Rate-limit state is cached per-instance; create one GitHubClient per GitHub token and reuse it to benefit from the cache.

Use When

Making authenticated GitHub API calls from the monitor or action packages where you need integrated rate-limit protection.

Avoid When

You need a full Octokit feature set with plugins (e.g., pagination, throttling) — instantiate Octokit directly and pass it to GitHubClient via the constructor is not possible; use the separate RateLimitHandler for advanced budget management.

Never

• Primary vs. secondary rate limits: checkRateLimit only checks the primary REST API rate limit. GitHub also enforces secondary (abuse) rate limits on burst patterns (many requests in a short window). A 403 with Retry-After header indicates a secondary limit — this class does not handle that automatically.
• Rate limit cache: getLastRateLimitCheck returns a potentially stale value; it is updated only when getRateLimit or checkRateLimit is called. Do not use it as a real-time indicator.

Example

import { GitHubClient } from '@dependabit/github-client';

const client = new GitHubClient({ auth: process.env.GITHUB_TOKEN });
const octokit = client.getOctokit();
const { data } = await octokit.rest.repos.get({ owner: 'my-org', repo: 'my-repo' });
