Rollup

Business Profile

Core Value Proposition

Rollup provides a JavaScript module bundler that compiles small pieces of code into larger, deployable libraries and applications.

Target Customer

Software developers and teams building JavaScript libraries and applications

Key Differentiator

Offers powerful tree-shaking (dead code elimination) with deep execution path analysis, a flexible and rich plugin API, and code-splitting capabilities, all while being non-opinionated and configurable. It is also described as the bundler behind Vite.

Implementation Timeline

Rapid setup and usage via command-line interface and JavaScript API; quick-start installation and examples are provided in the documentation

Pain Points

1Difficulty in combining multiple JS modules into a single deployable bundle for libraries and applications
2Historically limited native module support in browsers, requiring a bundler to integrate ES modules into usable builds
3Risk of bloated bundles due to unused code or large dependencies, requiring effective dead code elimination (tree-shaking)

Key Features

1Tree-shaking with dead code elimination
2Code-splitting without overhead based on entry points and dynamic imports
3Powerful plugin API for code injections and transformations
4Supports multiple output formats: ES modules, CommonJS, UMD, SystemJS and more
5Non-opinionated with a rich set of configuration options

Target Customer Industries

Client Results

1Produces lighter, faster, and less complicated libraries and applications due to minimal output and effective tree-shaking
2Enables building for web browsers and Node.js environments
3Facilitates output in multiple formats for compatibility with various toolchains

Competitive Advantages

1Superior dead code elimination through tree-shaking
2Flexible, plugin-based architecture that can be extended for custom builds
3Broad output format support (ES modules, CommonJS, UMD, SystemJS, etc.)
