Production best practices: performance and reliability

Overview

This article discusses performance and reliability best practices for Express applications deployed to production.

This topic clearly falls into the “devops” world, spanning both traditional development and operations. Accordingly, the information is divided into two parts:

• Things to do in your code (the dev part).
• Things to do in your environment / setup (the ops part).

Things to do in your code

Here are some things you can do in your code to improve your application’s performance:

• Use gzip compression
• Don’t use synchronous functions
• Do logging correctly
• Handle exceptions properly

Use gzip compression
