// summary

This TypeScript library provides a robust framework for implementing an OAuth 2.1 provider directly within Cloudflare Workers. It automates token management and request authentication, allowing developers to focus on building their API logic without handling complex security protocols. The framework is highly flexible, remaining agnostic to specific UI implementations and user management systems while ensuring secure storage through hashed secrets.

// technical analysis

This TypeScript library provides a robust OAuth 2.1 provider framework specifically architected for Cloudflare Workers, abstracting complex protocol requirements into a manageable wrapper. By handling token management, PKCE support, and RFC-compliant metadata discovery automatically, it allows developers to focus on core API logic rather than security boilerplate. The design prioritizes flexibility by remaining agnostic to UI frameworks and user authentication methods, while utilizing Cloudflare KV for secure, encrypted storage of authorization data.

// key highlights

01
Implements core OAuth 2.1 standards including PKCE support and RFC 8414/9728 metadata discovery.
02
Simplifies API development by automatically validating access tokens before passing requests to your custom handlers.
03
Supports dynamic client registration (RFC 7591) to allow programmatic management of OAuth clients.
04
Provides a flexible token exchange callback system for advanced scenarios like upstream token synchronization.
05
Ensures data security through end-to-end encryption of stored props and by storing only hashes of secrets.
06
Includes built-in maintenance utilities like purgeExpiredData to keep KV storage clean via Cron Triggers.

// use cases

01
Automated OAuth 2.1 token management and validation for API endpoints
02
Dynamic client registration and RFC-compliant metadata discovery
03
Secure, encrypted storage of grant metadata and custom user properties

// getting started

To begin, install the package and configure a Cloudflare Workers KV namespace named OAUTH_KV. Initialize the OAuthProvider in your worker entrypoint, defining your API routes, handlers, and endpoint URLs. Finally, implement the authorization UI and API logic using the provided helper methods available via the env.OAUTH_PROVIDER interface.
