IMPROVING NODE.JS LOADER PERFORMANCE

Node.js supports two types of modules: EcmaScript (ES) modules and CommonJS modules. ES modules are the official standard and are supported by modern browsers, while CommonJS modules are used by Node.js by default, but are not supported by browsers. Node.js determines which module loader to use based on the file extension: .mjs for ES modules, .cjs for CommonJS modules, and .js with package.json settings. This article discusses optimizations made to improve the performance of package.json reading and parsing in Node.js, ultimately resulting in faster applications.

CALL SITE ATTRIBUTION: HOW TO PINPOINT ROGUE SQL QUERIES THROTTLING DATABASE PERFORMANCE

This author explains how they added call site attribution to their Node.js web app to prepare for a potential 10x growth in database traffic. The attribution helped identify the specific location in the source code from which SQL queries were executed, allowing for quick identification and optimization of performance bottlenecks. Initially, they explored solutions like Datadog tracing and monkey patching, but eventually settled on requiring SQL queries to be tagged with a user-defined string indicating the call site.

DELETING 50,000 LINES OF CODE IN 3 DAYS

A developer recently deleted over 50,000 lines of code, approximately 70% of their frontend codebase, and surprisingly, this massive code removal didn't break the application and led to a significant simplification, making the platform feel lighter and more user-friendly. By carefully removing rarely used modules, screens, buttons, and features, they simplified the application, improved performance, and streamlined development.
