Restrict the number of API calls in nestjs

Is there a way to effectively limit the rate of my nestjs api calls? So far, I have explored various packages, but they all seem to limit based on the user's IP address.

Do you happen to know of any package that can achieve rate limiting using the user's access token instead?

If not, could you confirm if my understanding is correct?

IF (DB contains a record where [dbAccessToken === reqAccessToken])    
    IF (currentDate <= record.timestamp + limitSeconds) 
        => throw "Rate Limit Error"

...
=> Resolve Request 
=> Add record to DB

I believe my proposed solution could be effective, but I am concerned about the potential impact on the speed of the api.

Answer №1

When it comes to rate limiting, there are two main options to consider:

  • (Recommended): Set up rate limiting on the web server level (e.g. using nginx/apache) (check out this link for rate limiting with nginx )
  • Alternatively, you can integrate rate limiting directly into your application - there's a useful middleware compatible with express that can also be utilized with NestJS (https://www.npmjs.com/package/express-rate-limit)

You could also potentially incorporate your desired logic using NestJS Middleware (details provided here: https://docs.nestjs.com/middleware) - although I would caution against this approach due to its significant resource consumption!
