Tsup
tsup is a build tool designed for the automated compilation and packaging of TypeScript and JavaScript source code into compatible module formats. It functions as a TypeScript library bundler that transforms source files into distributable assets with minimal manual configuration.
The project provides a zero-config build pipeline that abstracts complex bundler settings into a simplified interface. It is an esbuild-based tool that produces simultaneous ESM and CommonJS output files from a single source tree to ensure broad environment compatibility.
The tool covers high-performance transpilation and minification, multi-entry point bundling, and type-stripping compilation. It also supports native Node.js formats, including JavaScript and JSON files.
Features
- TypeScript Bundling - Provides high-performance bundling of TypeScript projects into JavaScript distributions using esbuild.
- TypeScript Library Bundlers - Provides a high-performance tool for compiling and packaging TypeScript and JavaScript files into distributable library formats.
- JavaScript Module Format Converters - Produces bundles in ESM, CJS, IIFE, and UMD formats from a single source for broad compatibility.
- JavaScript Module Format Outputs - Generates bundles in multiple JavaScript module formats such as ESM and CJS for cross-environment compatibility.
- Zero-Config Library Packaging - Implements a simplified distribution workflow that packages libraries into optimized formats without requiring manual configuration files.
- esbuild Wrappers - Provides a high-performance build tool using esbuild to transform and minify TypeScript source code.
- TypeScript Compilation Utilities - Utilizes a high-performance engine to transform and minify TypeScript files into optimized production assets.
- TypeScript Transpilers - Uses a high-performance Go-powered engine to transform TypeScript into JavaScript without integrated type checking.
- JavaScript Library Packagers - Bundles modern source code into optimized distribution formats for various server-side and browser runtimes.
- Dual Module Formats - Produces simultaneous ESM and CommonJS output files from a single source tree for broad environment compatibility.
- Library Distribution Formats - Outputs code in multiple module formats like ESM and CJS to ensure compatibility across diverse JavaScript environments.
- Bundler Entry Points - Supports defining multiple starting files to bundle several entry points into separate distributable outputs.
- Source Bundling - Combines TypeScript, JavaScript, and JSON source files into single distributable output files.
- Automatic Entry Mapping - Scans the project structure to automatically map multiple source files to corresponding separate output bundles.
