How to: ![✔] 6.14. Limit payload size using a reverse-proxy or a middleware
**TL;DR:** The bigger the body payload is, the harder your single thread works in processing it. This is an opportunity for attackers to bring servers to their knees without tremendous amount of requests (DOS/DDOS attacks). Mitigate this limiting the body size of incoming requests on the edge (e.g. firewall, ELB) or by configuring [express body parser](https://github.com/expressjs/body-parser) to accept only small-size payloads

**Otherwise:** Your application will have to deal with large requests, unable to process the other important work it has to accomplish, leading to performance implications and vulnerability towards DOS attacks
