A single call to a synchronous function might return in a few microseconds or milliseconds, however in high-traffic websites, these calls add up and reduce the performance of the app. Synchronous functions and methods tie up the executing process until they return. For details on enabling gzip compression in Nginx, see Module ngx_http_gzip_module in the Nginx documentation. In that case, you do not need to use compression middleware. For example: const compression = require('compression')įor a high-traffic website in production, the best way to put compression in place is to implement it at a reverse proxy level (see Use a reverse proxy). Use the compression middleware for gzip compression in your Express app. Gzip compressing can greatly decrease the size of the response body and hence increase the speed of a web app.

Here are some things you can do in your code to improve your application’s performance: Things to do in your environment / setup (the ops part):.Things to do in your code (the dev part):.Accordingly, the information is divided into two parts: This topic clearly falls into the “devops” world, spanning both traditional development and operations. This article discusses performance and reliability best practices for Express applications deployed to production.
