SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bun-first provides a unified Bun-based workflow to replace Node.js-centric toolchains, reducing setup complexity and improving DX by using Bun as the runtime, package manager, and task runner.

Core Features & Use Cases

  • Unifies runtime, package manager, and task runner under Bun for seamless development.
  • Emphasizes Bun-native APIs and discourages Node.js-specific patterns to simplify code and environments.
  • Provides clear guidance for common development tasks, including running scripts, installing dependencies, testing with Vitest, and building with Vite.
  • Use Case: Teams migrating from npm/yarn/pnpm to Bun can streamline tooling and improve startup times.

Quick Start

Install dependencies with bun install, run your app with bun run, and execute tests with bun test to begin Bun-first development.

Frequently Asked Questions about bun-first

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I replace Node.js with Bun as my default JavaScript runtime?▼

Replace Node.js with Bun by adopting Bun as your unified runtime, package manager, and task runner. This approach enforces Bun-native APIs and discards Node.js-specific patterns to streamline script execution and improve development speed.

Can I use Bun with Vite and Vitest for building and testing?▼

Yes, Bun works with Vite and Vitest. A Bun-first workflow provides explicit guidance for building applications with Vite and running tests with Vitest, leveraging the Bun runtime to optimize startup times and script execution.

What is the best way to migrate from npm or yarn to Bun?▼

Migrate to Bun by replacing npm, yarn, or pnpm commands with bun install, bun add, and bun run. This unifies your package management and task execution under a single tool, minimizing setup complexity and ensuring deterministic dependency management.

Why should I use Bun instead of npm or pnpm for package management?▼

Use Bun instead of npm or pnpm to unify your runtime, package manager, and task runner. Bun-first practices guide minimal, deterministic dependency management and improve developer experience by reducing toolchain complexity and startup latency.

Are there limitations to using Bun-native APIs over Node.js-specific patterns?▼

A limitation of Bun-first practices is that they enforce Bun-native APIs and actively discourage Node.js-specific patterns. You must ensure your existing dependencies and environment are compatible with the Bun runtime before committing to a full migration.
