Nice content...just a very important point. This express rare limit library by default uses an in memory store to save the requests and control it. A very common use case is to put the api in aws lambdas or any other type of cloud function. This infrastructure is stateless..so the in memory store will not work. The nice thing is that the lib is already prepared to work with many external stores like mongo, redis.... So the infrastructure would be a little bit more complex in real life.. that would be great to have a video after 3 years showing how to implemeny this part!! 😂 Thanks
Good video but Server is replying for each time even after 5 request within 5 sec. So resources of Server is utilised lot. Is there any way, we can just block the attack without Server resource Utilised like WAF or Firewalls. Any way good video
Hello brother i am an engineering students and undergoing a internship and my role is full stack developer my problem statement is as follows DESCRIPTION The Distributed Denial of Service (DDoS) attack is an attack poses a server threat to the internet. It is difficult to find the exact sign of attacking. Moreover, it occurs when a huge number of users occasionally access the target at the same time. Using the entropy computing you should find the accuracy of an attack. TASK Write a program using entropy computing to detect DDOS attack. Steps: 1.Create a algorithm for sending data packets to the server. 2.Find Accuracy. plz help me what processes should i follow plz help 🙏🙏
sir, I have a confusion I think this time limiter can limit the actual user for example, if I set 5 requests in 5 seconds then if attacker requested 5 times then all the 5 requests will end and then when actual user request then they will get request limit over sir is there a way to limit the specific user request ??? for example, one user can only request 2 times in 5 second I think it will solve the problem if that method exists then please make a video on that
@@mafiacodes Same doubt! You should pin this comment. Also how does it identify the client to restrict that specific client, like cookies or something like that in request headers?
buddy recently i explore your channel , you have uploaded quality content please resume video uploading , I have seen it's been 1 year nothing new uploaded. till then I'll be watching your old videos.
There are so many ways to rate limit an app... one can do it also by configuring it in nginx at a lower level. But now that you touch this subject, and as it seems you know a lot, maybe a good idea would be to develop a gateway.

Suggestion - Sir make your channel a single point for nodejs backend content. Your explanation is easy to understand and simple.
Your lessons are as sweet as sugar. I learned a lot from you. Thank you 🌹
Great content king! Also worth mentioning the limit is per-ip-address
Thank you for this type of awesome content. Please make a detail video on rate-limit-flexible
Thanks Man!
I failed my interview today because of this, thanks for a explanation
Useful. Thank you!
Glad it was helpful!
Great Tutorial. Waiting for more videos
Great info

for 10 req in login, i have applied 60*60*1000 ms, but the user can login after 4-5 minute why?
Great Tutorial. This restriction is based on per IP. Any suggestions to block requests from particular geographic location?
Use nginx plugin to black by geolocation

can we use this for a dynamic website?? as professional we we need to change something to prevent DDOS attack

Bro it is per client, everyone has their kitty of 5 requests

Using the clients IP
Hi completely enjoyed it and I have one doubt. Prevent from brute force we can lock the user for 3 invalid password attempts right?
Yes u can specify the route also - like 3 attempts and then block for n number of hours
buddy recently i explore your channel , you have uploaded quality content please resume video uploading , I have seen it's been 1 year nothing new uploaded. till then I'll be watching your old videos.
thank you for your video ... but i have a question this limit request for each user that request or for all users that request to the server ?
Per user based on IP address

Also in your start script is enough to just write"nodemon", and node will fill in the blank with the "main" property.
Can u share what zsh theme Ur using
Oh my zsh Robby Russel with space ship prompt
How to prevent ddos attack? Because the IP will be different
So it's only for dos attack
The hacker maybe using bots, thousands of bots, how are we going to avoid that?
3:55
So how this method will prevent a brute force attack
Explained in video itself
@@mafiacodesuser could still make request after some time. So doesn't work much unless you restrict for long hours
This seems to be useless. What if the attacker sends requests using a loop?
wdum useless?

U have to implement ur own logic

This is not a free course you stole this and now you are using it in your channel. @andrew
lol I guess sending back a json response for each request saying that "you are doing too much" is less expensive. what a useless video
