koa-jwt is a Koa middleware for authenticating HTTP requests using JSON Web Tokens. It validates JWTs from headers or cookies and exposes the decoded payload to downstream middleware for authorization.

Use cases

• add jwt authentication to a koa api
• validate bearer tokens in node.js http requests
• protect koa routes with token auth
• read jwt from a cookie in koa
• set authenticated user on request state for authorization

When to choose

• your app is built on Koa and you need standard JWT bearer/cookie authentication
• you want a small, focused middleware rather than a full auth framework
• you need token revocation checks and custom secret handling

When to avoid

• you use Express or Fastify rather than Koa
• you need full identity management with sessions, OAuth, or user registration
• you need non-JWT auth schemes like basic auth or SAML
