## What it is
simple-oauth2 is a Node.js client library for the OAuth 2.0 authorization framework. It supports the authorization code, resource owner password credentials, and client credentials grant types, plus token refresh and revocation.

## Use cases
- implement oauth2 authorization code flow in node.js
- get access tokens via client credentials grant
- refresh expired oauth2 access tokens
- revoke oauth2 access or refresh tokens
- authenticate against an oauth2 api from a node backend
- handle oauth2 password grant authentication

## When to choose
- you need a lightweight, focused oauth2 client in Node.js
- you want support for the common grant types without a full framework
- you need token refresh and revocation helpers

## When to avoid
- you need an oauth2 server or provider implementation
- you need OpenID Connect features beyond plain OAuth2
- you need a framework-integrated auth middleware solution

## Facets
- artifact type: library
- maturity: active
- function: auth, http-client
- domain: security, web-development, apis
- platform: -
- tags: oauth2, access-token, grant-types, token-refresh, nodejs
