1 Open Source Alternatives to Rollup

Rollup is a powerful tool for compiling JavaScript code, offering a range of features and options to developers. With Rollup, you can build libraries or applications with ease. It supports ES modules, which are the future of JavaScript code structure, providing static analysis for optimizations like tree-shaking and scope-hoisting. The tree-shaking process eliminates unused code, resulting in more efficient output size. Rollup also offers plugins for loading CommonJS modules and using Node's module location resolution logic. While these features are not included by default, installing the commonjs and node-resolve plugins enables their functionality. Additionally, Rollup allows you to add polyfills to your bundle, ensuring correct execution order for external dependencies. With its focus on lean core and good API design, Rollup ensures efficient software development and minimizes potential technical debt. Whether you're building libraries or applications, Rollup provides the tools you need for seamless JavaScript compilation.
