5 Tips to Make Your NodeJs App Faster and More Secure

They are easily forgotten but make a big difference

As a Node.js developer, I am constantly impressed by the efficiency, feature-richness, and powerful tools available. However, it’s easy for developers like myself to get caught up in the nitty-gritty of coding and overlook important factors affecting an application’s performance and security.

Let’s Walk through some tips and tricks.

1) Enable Gzip compression

It’s surprising how often Gzip is forgotten to be turned on. Turning on gzip compression can make your App much faster by reducing the size of HTTP calls up to 10 times.

How to verify whether it’s enabled? Just open the App in Chrome, open chrome Devtools, select the “networks” tab, then look for Content-Encoding under the “Response Headers”.

How to enable it? it can be done either via NodeJS App or by configuring your reverse Proxy, i.e., Nginx.

If you’re using NestJS, you can use the compression middleware package provided to compress and serve content.

2) Rate limiting

Rate limiting is essential to make your NodeJs App secure and scalable.
