Using tsup to bundle your TypeScript package

tsup is a modern, zero-configuration TypeScript and JavaScript bundler that streamlines the process of compiling and optimizing projects by leveraging esbuild for high-speed performance. It supports multiple module formats, including ESM and CJS, and offers features like tree shaking, minification, and code splitting. By automatically handling TypeScript compilation and bundling, tsup simplifies the creation of optimized, production-ready code without requiring extensive configuration. Developers can customize output file extensions using the outExtension option, ensuring compatibility with different environments, and can manage multiple entry points and external dependencies to improve efficiency and modularity. tsup's approach reduces setup complexity, allowing developers to focus on development rather than configuration, and it integrates smoothly into broader toolchains for building and deploying TypeScript projects.
