## What it is
A Node.js module for implementing a fully RFC 6749/6750 compliant OAuth2 server/provider, framework-agnostic with official wrappers for Express and Koa. It supports authorization_code, client_credentials, refresh_token, password, and extension grants with scopes.

## Use cases
- implement an OAuth2 authorization server in Node.js
- add OAuth2 token issuance to an Express API
- support client credentials and password grants
- build a compliant OAuth2 provider with custom storage backend
- handle refresh token flows in a Node.js app

## When to choose
- you need standards-compliant OAuth2 server behavior in Node.js
- you use Express or Koa and want an official wrapper
- you want flexibility over the token storage backend

## When to avoid
- you only need OAuth client/consumer functionality rather than a server
- you need OpenID Connect or full identity provider features
- you are not on a supported Node.js release
