Typescript Library Starter

Starter kit with zero-config for building a library in TypeScript, featuring RollupJS, Jest, Prettier, TSLint, Semantic Release, and more!


This product is a TypeScript library starter project that aims to make it easy to create a TypeScript library. It provides a setup that includes various features and tools to streamline the development process and improve code consistency.


  • Zero-setup: After running npm install, the project is set up with npm package.json and entry files.
  • RollupJS: Multiple optimized bundles are created following the standard convention and Tree-shaking.
  • Tests and coverage: Jest is used for testing, coverage reports, and an interactive watch mode.
  • Prettier and TSLint: Code formatting and consistency tools are integrated.
  • Docs generation: Automatic generation and deployment of documentation to GitHub Pages using TypeDoc.
  • Automatic types generation: Declaration files (*.d.ts) are automatically generated.
  • Travis integration and Coveralls report: Integration with Travis CI for continuous integration and Coveralls for report generation.
  • Optional automatic releases and changelog: Integration with Semantic release, Commitizen, Conventional changelog, and Husky for automatic releases and changelog generation.


To install the theme and set up the project, follow these steps:

  1. Run npm install to install the necessary dependencies.
  2. Start coding! The package.json and entry files are already set up, so there's no need to worry about linking to the main file or typings.


This product is a starter project that simplifies the process of creating a TypeScript library. It provides a zero-setup environment with pre-configured tools and features such as RollupJS for optimized bundles, Jest for testing, Prettier and TSLint for code formatting, and TypeDoc for documentation generation. It also offers options for automatic releases and changelog generation through integration with Semantic release, Commitizen, Conventional changelog, and Husky. Overall, this project aims to make the development process more efficient and consistent for TypeScript library creators.


RollupJS is a popular and efficient JavaScript module bundler that takes the code from multiple modules and packages them into a single optimized file, minimizing the overall size of the application and improving its performance.


TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.


Webpack is a popular open-source module bundler for JavaScript applications that bundles and optimizes the code and its dependencies for production-ready deployment. It can also be used to transform other types of assets such as CSS, images, and fonts.
