How can I implement rate limiting in my Vue.js application?

You can implement rate limiting in your Vue.js application by using middleware on your API server. This can be done using libraries like express-rate-limit for Express.js.

Can you show me a code example of how to set that up?

Sure! Here's a simple example:

const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

app.use(limiter);

This will limit each IP to 100 requests every 15 minutes.

What if I want to customize the response when the limit is reached?

You can customize the response by adding a handler function to the rate limiter options. For example:

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000,
  max: 100,
  handler: (req, res) => {
    res.status(429).json({ message: 'Too many requests, please try again later.' });
  }
});
