## What it is
Knock is a Ruby gem providing seamless JWT-based authentication for Rails API-only applications. It integrates with Rails controllers via an Authenticable module to authenticate users from JSON Web Tokens.

## Use cases
- add jwt authentication to a rails api
- authenticate api requests with json web tokens
- get current_user in rails controllers from a token
- protect rails api endpoints with before_action auth
- token-based login for api-only rails apps

## When to choose
- you maintain a legacy Rails API already using Knock
- you need a minimal JWT auth layer tightly integrated with Rails controllers

## When to avoid
- you are starting a new project - the maintainer explicitly recommends against using it
- you want actively maintained software with security updates
- you can use the ruby-jwt gem directly instead

## Facets
- artifact type: library
- maturity: abandoned
- function: auth, middleware
- domain: web-development, backend, security, apis
- platform: ruby
- tags: jwt, rails, api-only, token-authentication, unmaintained, web-server
