bun-build 命令

常用示例

说明

bun build is Bun's fast native bundler for JavaScript and TypeScript. It bundles code for production, generates standalone executables, and supports both server and client code in a single command. The bundler automatically performs tree-shaking to eliminate unused code. It can target multiple runtimes including browsers, Node.js, and Bun itself. The --compile flag creates self-contained executables with the Bun runtime embedded, enabling distribution without requiring users to install Bun. Code splitting, source maps, and minification are supported through command-line flags or the equivalent JavaScript API via Bun.build().
