Prevent DOS and DDOS attack with sailjs app

Question

I'm using sails js in developing a node js application and I want to apply some prevention for DOS and DDOS attack, I see "express-rate-limit" and "express-limiter" packages, In express it is easy to implement using

app.use(limiter({ some parameters }))

but how to implement using sailsjs app?

Answer 1

Use rate-limiter-flexible, which is not bound to any framework.

Here is basic example:

const opts = {
  points: 6, // 6 points
  duration: 1, // Per second
};

const rateLimiter = new RateLimiterMemory(opts);

rateLimiter.consume(remoteAddress, 2) // consume 2 points
    .then((rateLimiterRes) => {
      // 2 points consumed
    })
    .catch((rateLimiterRes) => {
      // Not enough points to consume
    });

There are a lot more examples on a package Wiki.
