Rollup Javascript

Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application.

#What is Rollup?

Rollup is a popular JavaScript module bundler that helps developers bundle their code and dependencies into a single file. Unlike other bundlers that bundle all the code and dependencies together, Rollup creates an optimized bundle by only including the code that is actually used, resulting in a smaller bundle size and improved performance.

#Rollup Key Features

Most recognizable Rollup features include:

  • its support for tree shaking, which eliminates unused code and dependencies,
  • its ability to generate code in a variety of formats, including CommonJS, AMD, and ES6
  • support for plugins that can be used to transform or optimize the code during the bundling process.

#Rollup Use-Cases

Some of the Rollup use-cases are:

  • including building libraries,
  • creating web applications,
  • optimizing server-side code
  • used with a range of front-end frameworks

#Rollup Summary

Rollup is a powerful JavaScript module bundler that enables developers to create optimized bundles by only including the code that is actually used, resulting in smaller bundle sizes and improved performance. Its support for tree shaking, code transformation, and code generation makes it a popular choice for a variety of use cases.
