Rollup

Rollup is the precision JavaScript bundler trusted by libraries like Vue.js, React, and D3 to create ultra-efficient bundles through advanced tree-shaking optimization. As the preferred tool for library authors and performance-conscious developers, it produces cleaner, smaller bundles by leveraging ES modules’ static structure to eliminate dead code with surgical precision.

What makes Rollup exceptional is its focus on ES modules and intelligent static analysis that results in remarkably clean output code. Unlike other bundlers that wrap modules in complex runtime code, Rollup flattens your module graph into efficient, readable JavaScript that browsers and other tools can optimize further.

Development teams choose Rollup because it delivers the smallest possible bundle sizes without sacrificing code quality or debugging capability. From open source libraries to enterprise applications, it provides the performance-focused foundation that modern JavaScript projects demand.
