Configuring Webpack, maintaining npm packages, debugging build pipelines, this often costs more time in Symfony projects than the actual frontend logic. Symfony AssetMapper makes the bundler unnecessary for most projects: import maps, automatic versioning and ES modules directly from PHP, without a Node.js build step.

requestAnimationFrame is the only correct way to implement animations in the browser. Anyone using setTimeout or setInterval is fighting the rendering cycle instead of working with it. This article shows how rAF works, how to build a robust render loop, and which traps destroy the frame rhythm.

A cookie consent banner decides directly whether tracking scripts, marketing pixels and third party embeds are allowed to load at all.

Few concepts in JavaScript cause as much confusion as this binding. A method works perfectly when called directly and suddenly returns undefined when passed as a callback. This article shows where this binding typically breaks, how to debug it systematically and which fix actually fits which situation.
