Bun Runtime

Overview

Bun is an all-in-one JavaScript and TypeScript runtime that includes a fast package manager, bundler, test runner, and Node.js-compatible APIs. It natively executes TypeScript and JSX without a separate compilation step.

When to use: Fast server-side JavaScript, TypeScript-first projects, replacing Node.js for better startup performance, built-in SQLite, password hashing, file I/O, HTTP servers, bundling, and testing without external tooling.

When NOT to use: Projects requiring full Node.js ecosystem compatibility (some native modules unsupported), production environments needing battle-tested stability of Node.js, or browser-only code that does not need a runtime.

Quick Reference

Pattern API Key Points
HTTP server Bun.serve({ routes, fetch }) Route-based, static/dynamic routes, per-method handlers
File read Bun.file(path) Lazy BunFile (Blob), .text(), .json(), .stream()
File write Bun.write(dest, data) Accepts string, Blob, Response, BunFile
SQLite new Database(path) from bun:sqlite Synchronous queries, prepared statements, WAL mode
Password hash Bun.password.hash(pw) Argon2id default, bcrypt option, async and sync variants
Password verify Bun.password.verify(pw, hash) Auto-detects algorithm from hash format
Bundler Bun.build({ entrypoints, outdir }) Tree-shaking, code splitting, plugins, multiple targets
Test runner import { test, expect } from "bun:test" Jest-compatible, mocking, snapshots, watch mode
Install packages bun install Fast lockfile resolution, npm-compatible
Add package bun add <pkg> -d for dev, -g for global
Run script bun run <script> Runs package.json scripts or files directly
Execute binary bunx <pkg> Like npx, runs without installing
S3 client new S3Client(opts) / s3.file(key) Built-in S3-compatible storage client
HTML imports import page from './index.html' Fullstack: import HTML as route handler

Common Mistakes

Mistake Correct Pattern
Using fetch handler only without routes Use routes object for static/dynamic routing (Bun v1.2.3+), fetch as fallback
Forgetting await on Bun.write() Bun.write() is async, always await it
Using Bun.file(path).text() without await .text(), .json(), .arrayBuffer() all return Promises
Creating SQLite database without WAL mode Enable WAL for concurrent reads: db.exec("PRAGMA journal_mode = WAL")
Using bun install without --frozen-lockfile in CI Use bun install --frozen-lockfile for reproducible CI builds
Importing jest globals in Bun tests Import from bun:test, not @jest/globals or vitest
Using node_modules/.bin/ directly Use bunx or bun run instead of referencing bin paths
Expecting Bun.build() to throw on failure Check result.success boolean, errors are in result.logs
Using --target node when deploying to Bun Use --target bun for Bun-specific optimizations and bytecode
Synchronous password hashing in request handlers Use await Bun.password.hash() async variant in servers

Delegation

  • Project scaffolding: Use Explore agent
  • Performance profiling: Use Task agent
  • Code review: Delegate to code-reviewer agent

If the typescript-patterns skill is available, delegate advanced TypeScript typing questions to it.

So verwenden Sie diesen Skill

1

Install bun-runtime by running npx skills add oakoss/agent-skills --skill bun-runtime in your project directory. Führen Sie den obigen Installationsbefehl in Ihrem Projektverzeichnis aus. Die Skill-Datei wird von GitHub heruntergeladen und in Ihrem Projekt platziert.

2

Keine Konfiguration erforderlich. Ihr KI-Agent (Claude Code, Cursor, Windsurf usw.) erkennt installierte Skills automatisch und nutzt sie als Kontext bei der Code-Generierung.

3

Der Skill verbessert das Verständnis Ihres Agenten für bun-runtime, und hilft ihm, etablierte Muster zu befolgen, häufige Fehler zu vermeiden und produktionsreifen Code zu erzeugen.

Was Sie erhalten

Skills sind Klartext-Anweisungsdateien — kein ausführbarer Code. Sie kodieren Expertenwissen über Frameworks, Sprachen oder Tools, das Ihr KI-Agent liest, um seine Ausgabe zu verbessern. Das bedeutet null Laufzeit-Overhead, keine Abhängigkeitskonflikte und volle Transparenz: Sie können jede Anweisung vor der Installation lesen und prüfen.

Kompatibilität

Dieser Skill funktioniert mit jedem KI-Coding-Agenten, der das skills.sh-Format unterstützt, einschließlich Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider und anderen Tools, die projektbezogene Kontextdateien lesen. Skills sind auf Transportebene framework-agnostisch — der Inhalt bestimmt, für welche Sprache oder welches Framework er gilt.

Data sourced from the skills.sh registry and GitHub. Install counts and security audits are updated regularly.
