Why can't I use MSAL.js in Cloudflare Workers?

MSAL.js relies on browser-specific APIs and Node.js crypto modules which are unavailable in Cloudflare's V8 isolate runtime. This skill provides manual fetch patterns that work natively in edge environments.

How do I handle users with private emails on GitHub?

If the primary /user endpoint returns a null email, you must use the 'user:email' scope and specifically fetch the /user/emails endpoint to retrieve the primary verified address.

Why does my GitHub API request return a 403 error?

GitHub requires a User-Agent header for all API requests. Even with a valid token, the API will reject requests that do not include this header.

What scope is required for Microsoft Graph user info?

The 'User.Read' scope is mandatory for accessing the /me endpoint. Without it, your token exchange will succeed but you will be unable to retrieve the user's profile data.

How do I implement persistent sessions in edge environments?

Include the 'offline_access' scope in your Microsoft Entra request to receive a refresh token, allowing you to renew access tokens without requiring the user to log in again.

Implements robust OAuth 2.0 flows for GitHub and Microsoft Entra within Cloudflare Workers and other edge runtimes.

This skill provides specialized guidance for implementing OAuth 2.0 authentication in edge environments where standard libraries like MSAL.js often fail due to runtime limitations. It offers specific patterns for GitHub and Microsoft Entra (Azure AD), covering critical header requirements, private email retrieval, manual token exchange, and JWT validation using edge-compatible libraries. It is an essential resource for developers building serverless applications on Cloudflare Workers who need to handle user identity and secure API access without relying on traditional Node.js modules or browser APIs.
