is there a way to use different rate limit for each api key in express nodejs?

is there a way to use different rate limit for each api key in express nodejs?

for example api key "guest" has a rate limit of 500 requests per day and api key "key" has a rate limit of 1000 requests per day.

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

const app = express();

// Define rate limit middleware for API1
const api1Limiter = rateLimit({
  max: 50,  // Maximum requests
  windowMs: 60 * 60 * 1000,  // 1 hour window
  message: 'Too many requests from this IP for API1, please try again in an hour!',
});

// Define rate limit middleware for API2
const api2Limiter = rateLimit({
  max: 100,  // Maximum requests
  windowMs: 60 * 60 * 1000,  // 1 hour window
  message: 'Too many requests from this IP for API2, please try again in an hour!',
});

// Apply rate limit middleware to specific routes
app.use('/api/api1', api1Limiter);
app.use('/api/api2', api2Limiter);

// Your API routes go here...

// Start the server
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

the simple solution is to use an npm package called express-rate-limit, it's a popular one and express recommend to use it.

If the package doesn't work for you, it can be implemented using redis, redis is a memory database, so you can create a record with a sliding time. When a request come in you can update or create the record, if the limit was reached you block the request, that logic can be implemented in a middleware.
