@tjorim, I've identified several routes that handle HTTP requests and might benefit from rate limiting. Below are the proposed changes to add rate limiting using the express-rate-limit library.

1. Install the express-rate-limit package:

   npm install express-rate-limit

2. Update the routes to include rate limiting:

   • src/routes/user.js:

     const express = require('express');
     const rateLimit = require('express-rate-limit');
     const router = express.Router();
     
     // Apply rate limiting to all routes in this router
     const limiter = rateLimit({
     windowMs: 15 * 60 * 1000, // 15 minutes
     max: 100, // limit each IP to 100 requests per windowMs
     });
     
     router.use(limiter);
     
     router.get('/', async (req, res) => {
     console.log('GET HTTP method on users resource');
     const users = await req.context.models.User.find();
     return res.send(users);
     });
     
     router.get('/:userId', async (req, res) => {
     console.log('GET HTTP method on user');
     const user = await req.context.models.User.findById(req.params.userId);
     return res.send(user);
     });
     
     // ... other routes ...
     
     module.exports = router;

   • src/routes/message.js:

     const express = require('express');
     const rateLimit = require('express-rate-limit');
     const router = express.Router();
     
     // Apply rate limiting to all routes in this router
     const limiter = rateLimit({
     windowMs: 15 * 60 * 1000, // 15 minutes
     max: 100, // limit each IP to 100 requests per windowMs
     });
     
     router.use(limiter);
     
     router.get('/', async (req, res) => {
     console.log('GET HTTP method on messages resource');
     const messages = await req.context.models.Message.find();
     return res.send(messages);
     });
     
     router.get('/:messageId', async (req, res) => {
     console.log('GET HTTP method on message');
     const message = await req.context.models.Message.findById(req.params.messageId);
     return res.send(message);
     });
     
     // ... other routes ...
     
     module.exports = router;

   • src/routes/session.js:

     const express = require('express');
     const rateLimit = require('express-rate-limit');
     const router = express.Router();
     
     // Apply rate limiting to all routes in this router
     const limiter = rateLimit({
     windowMs: 15 * 60 * 1000, // 15 minutes
     max: 100, // limit each IP to 100 requests per windowMs
     });
     
     router.use(limiter);
     
     router.get('/', async (req, res) => {
     const user = await req.context.models.User.findById(req.context.me.id);
     return res.send(user);
     });
     
     module.exports = router;

   • src/index.js:

     const express = require('express');
     const rateLimit = require('express-rate-limit');
     const app = express();
     
     // Apply rate limiting to all routes
     const limiter = rateLimit({
     windowMs: 15 * 60 * 1000, // 15 minutes
     max: 100, // limit each IP to 100 requests per windowMs
     });
     
     app.use(limiter);
     
     app.get('/', (req, res) => res.send('Received a GET HTTP method'));
     app.post('/', (req, res) => res.send('Received a POST HTTP method'));
     app.put('/', (req, res) => res.send('Received a PUT HTTP method'));
     app.delete('/', (req, res) => res.send('Received a DELETE HTTP method'));
     
     // ... other middleware and routes ...
     
     module.exports = app;
