Package: npm install --save rate-limit-mongo

ROUTE:

routes.get(
    "/example",
    general,  // This is my rate limit
    (req, res) => {
    return res.status(201).end()
    }
)

MIDDLEWARE:

module.exports.general = new RateLimit({
store: new MongoStore({
    uri: process.env.MONGODB_CNN + "api-limiter",
    expireTimeMs: 15 * 60 * 1000,
    errorHandler: console.error.bind(null, 'rate-limit-mongo'),
    collectionName: "general",
}),
max: 50,
windowMs: 15 * 60 * 1000,
skipSuccessfulRequests: true
});

Thank you in advance
