# Bun Bundler Bun's bundler is a fast JavaScript/TypeScript bundler built on the same engine as Bun's runtime. It's an esbuild-compatible alternative with native performance. ## Quick Start ### CLI ```bash # Basic bundle bun build ./src/index.ts --outdir ./dist # Production build bun build ./src/index.ts --outdir ./dist --minify # Multiple entry points bun build ./src/index.ts ./src/worker.ts --outdir ./dist ``` ### JavaScript API ```typescript const result = await Bun.build({ entrypoints: ["./src/index.ts"], outdir: "./dist", }); if (!result.success) { console.error("Build failed:", result.logs); } ``` ## Bun.build Options ```typescript await Bun.build({ // Entry points (required) entrypoints: ["./src/index.ts"], // Output directory outdir: "./dist", // Target environment target: "browser", // "browser" | "bun" | "node" // Output format format: "esm", // "esm" | "cjs" | "iife" // Minification minify: true, // or { whitespace: true, identifiers: true, syntax: true } // Code splitting splitting: true, // Source maps sourcemap: "external", // "none" | "inline" | "external" | "linked" // Naming patterns naming: { entry: "[dir]/[name].[ext]", chunk: "[name]-[hash].[ext]", asset: "[name]-[hash].[ext]", }, // Define globals define: { "process.env.NODE_ENV": JSON.stringify("production"), }, // External packages external: ["react", "react-dom"], // Loaders loader: { ".svg": "text", ...
