In their own words
esbuild
esbuild is a free bundler for web projects, designed to improve build-tool performance while remaining easy to use. It bundles ESM and CommonJS modules, including CSS modules, with built-in support for JavaScript, CSS, TypeScript and JSX. Optimization features include tree shaking, minification and source maps; development tools include a local server, watch mode and plugins. Developers can use the command-line, JavaScript or Go interface. The recommended installation is the native executable installed with npm. An alternative WebAssembly package works across platforms, though it can be substantially slower than the native package. esbuild is MIT-licensed. It does not type-check TypeScript, and its FAQ recommends running tsc separately. The FAQ describes code-splitting support as primitive. The maintainer says the project receives periodic releases and is maintained, but active feature development is not underway. The FAQ also notes that a project primarily built by one developer may not fit organizations seeking a larger or more active community.
