# 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 // Since Bun 1.2, Bun.build REJECTS on failure (throws). // Wrap in try/catch to handle errors; pass { throw: false } to restore the // old resolve-with-{ success, logs } contract if you prefer that style. try { const result = await Bun.build({ entrypoints: ["./src/index.ts"], outdir: "./dist", }); console.log(`Built ${result.outputs.length} files`); } catch (err) { console.error("Build failed:", err); process.exit(1); } ``` ## 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]", ...
