How do I implement an API Gateway in my application?

To implement an API Gateway, you can use services like AWS API Gateway or Kong. What technology stack are you using?

I'm using Node.js and Express. Can you guide me through the setup?

Sure! First, you'll need to install the necessary packages. You can use 'express-gateway' for a Node.js setup. Would you like a code example?

Yes, please provide a simple code example.

Here's a basic setup:

const express = require('express');
const gateway = require('express-gateway');

const app = express();

app.use(gateway({
  routes: [
    {
      // Define your routes here
      'api': {
        target: 'http://your-backend-service',
        // other configurations
      }
    }
  ]
}));

app.listen(3000, () => console.log('API Gateway running on port 3000')); 

This will route requests to your backend service.
