GitHub App vs OAuth App

Choose a GitHub App over an OAuth App for repository access to ensure secure, scoped operations. GitHub Apps provide a distinct bot identity, per-repository scoping, and short-lived installation tokens, reducing security risks compared to OAuth Apps.

To mint short-lived installation tokens for a GitHub App, authenticate using the securely stored `GITHUB_APP_PRIVATE_KEY` to generate tokens on demand. This ensures that repository access tokens are short-lived and minted only when needed for secure integration.

Yes, you can use a GitHub App for repository access in a Next.js application. This approach is applicable to Next.js and Clerk-based applications, ensuring secure, scoped access to GitHub repositories through bot identity and per-repo permissions.

Registering an OAuth App for repository operations is an anti-pattern because it lacks the granular, per-repo scoping and bot identity of a GitHub App. OAuth Apps use long-lived user tokens, which creates a broader security exposure for repository access.

GitHub Apps offer per-repo scoping and short-lived installation tokens, limiting access to specific repositories. OAuth Apps typically have broader, user-level scoping and longer-lived tokens, making GitHub Apps the more secure choice for repository integration.
