@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.

Install the express-rate-limit package:
```
npm install express-rate-limit
```

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;

Learning: When addressing missing rate limiting in an Express.js application, use the `express-rate-limit` library to apply rate limiting middleware to relevant routes.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.
