simple-api-gateway

This is a proof of concept API Gateway based on Express.JS

Routes and targets are configured using a YAML file like this

auth:
  enabled: true
services:
  - serviceKey: "dadJokesService"
    serviceDescription: "An API for dad jokes"
    routes:
      - path: "/dad"
        method: "GET"
        target: "https://icanhazdadjoke.com/"
        enabled: true
  - serviceKey: "chuckNorrisJokesService"
    serviceDescription: "An API for Chuck Norris jokes"
    routes:
      - path: "/chuck" 
        method: "GET"
        target: "https://api.chucknorris.io/jokes/random"
        enabled: true        

Ideas:

• Support other HTTP methods :)
• Session Management
• Cross-Site Request Forgery (CSRF) protection
• Cross-Origin Resource Sharing (CORS)
• Rate Limiting
• Logging
