When should you use tree shaking?

Tree shaking is a powerful optimization technique used during the build process of web applications, primarily for JavaScript. It helps in removing unused code from your final bundle, resulting in smaller file sizes and improved load times. You should consider using tree shaking in the following scenarios:

  • When building a large application with numerous dependencies.
  • When using modern JavaScript frameworks or libraries like React, Vue, or Angular.
  • When optimizing for performance and load time, especially for production builds.
  • When using ES6 modules, as tree shaking relies on static analysis of imports and exports.

Implementing tree shaking can significantly enhance your application's efficiency, making it faster and more responsive to users.
