# 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);
