  • Runtime, package manager, bundler, and test runner in a single toolchain for JS/TS projects.
  • Migration guidance for moving from Node to Bun and optimized deployments on platforms like Vercel.
  • Suitable for new projects and rapid iteration, especially where startup time and simplicity matter.

Quick Start

Install Bun and begin using bun install, bun run, and bun test to streamline development and deployments.

Frequently Asked Questions about bun-runtime

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

FAQPage Schema
When should I choose Bun over Node for my JavaScript runtime?▼

Choose Bun over Node when you need faster startup times and want a single toolchain for runtime, package management, bundling, and testing in new JS or TS projects. Bun excels in rapid iteration scenarios where reducing tool fragmentation and accelerating deployments matter.

How do I migrate an existing Node.js project to Bun?▼

To migrate a Node project to Bun, you transition your runtime, package manager, and test runner to Bun's equivalents. You replace standard commands with `bun install`, `bun run`, and `bun test` to consolidate your toolchain and accelerate development.

Does Bun work for deployments on Vercel?▼

Yes, Bun is suitable for optimized deployments on Vercel. Using Bun as your runtime and package manager on Vercel accelerates deployment speeds and reduces tool fragmentation for JavaScript and TypeScript projects.

Can I use Bun for bundling and testing instead of separate Node tools?▼

Yes, Bun provides an all-in-one toolchain that replaces separate Node tools for bundling and testing. You can use `bun test` for running tests and Bun's built-in bundler to streamline your development process without extra dependencies.

What are the limitations of using Bun as a Node replacement?▼

While Bun offers performance gains, its limitation lies in Node compatibility for existing projects. You must evaluate compatibility considerations when migrating, as some Node-specific modules or existing tool configurations might not be fully supported.

What is the best way to start a new TypeScript project with Bun?▼

The best way to start a new TypeScript project with Bun is to install the Bun runtime and immediately use `bun install`, `bun run`, and `bun test` for rapid iteration. This leverages Bun's fast startup time and built-in TS support.
