This skill should be used when the user asks about "bun build", "Bun.build", "bundling with Bun", "code splitting", "tree shaking", "minification", "sourcemaps", "bundle optimization", "esbuild alternative", "building for production", "bundling TypeScript", "bundling for browser", "bundling for Node", or JavaScript/TypeScript bundling with Bun.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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

How to install
mdr add secondsky/claude-skills/bun-bundler@sha256:f4ee876e535d00adThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
