Bun Runtime
Bun is a fast all-in-one JavaScript runtime and toolkit: runtime, package manager, bundler, and test runner.
When to Use
- Prefer Bun for: new JS/TS projects, scripts where install/run speed matters, Vercel deployments with Bun runtime, and when you want a single toolchain (run + install + test + build).
- Prefer Node for: maximum ecosystem compatibility, legacy tooling that assumes Node, or when a dependency has known Bun issues.
Use when: adopting Bun, migrating from Node, writing or debugging Bun scripts/tests, or configuring Bun on Vercel or other platforms.
How It Works
- Runtime: Drop-in Node-compatible runtime (built on JavaScriptCore, implemented in Zig).
- Package manager:
bun installis significantly faster than npm/yarn. Lockfile isbun.lock(text) by default in current Bun; older versions usedbun.lockb(binary). - Bundler: Built-in bundler and transpiler for apps and libraries.
- Test runner: Built-in
bun testwith Jest-like API.
Migration from Node: Replace node script.js with bun run script.js or bun script.js. Run bun install in place of npm install; most packages work. Use bun run for npm scripts; bun x for npx-style one-off runs. Node built-ins are supported; prefer Bun APIs where they exist for better performance.
Vercel: Set runtime to Bun in project settings. Build: bun run build or bun build ./src/index.ts --outdir=dist. Install: bun install --frozen-lockfile for reproducible deploys.
Examples
Run and install
# Install dependencies (creates/updates bun.lock or bun.lockb)
bun install
# Run a script or file
bun run dev
bun run src/index.ts
bun src/index.ts
Scripts and env
bun run --env-file=.env dev
FOO=bar bun run script.ts
Testing
bun test
bun test --watch
// test/example.test.ts
import { expect, test } from "bun:test";
test("add", () => {
expect(1 + 2).toBe(3);
});
Runtime API
const file = Bun.file("package.json");
const json = await file.json();
Bun.serve({
port: 3000,
fetch(req) {
return new Response("Hello");
},
});
Best Practices
- Commit the lockfile (
bun.lockorbun.lockb) for reproducible installs. - Prefer
bun runfor scripts. For TypeScript, Bun runs.tsnatively. - Keep dependencies up to date; Bun and the ecosystem evolve quickly.

# Bun Runtime
Bun is a fast all-in-one JavaScript runtime and toolkit: runtime, package manager, bundler, and test runner.
## When to Use
- **Prefer Bun** for: new JS/TS projects, scripts where install/run speed matters, Vercel deployments with Bun runtime, and when you want a single toolchain (run + install + test + build).
- **Prefer Node** for: maximum ecosystem compatibility, legacy tooling that assumes Node, or when a dependency has known Bun issues.
Use when: adopting Bun, migrating from Node, writing or debugging Bun scripts/tests, or configuring Bun on Vercel or other platforms.
## How It Works
- **Runtime**: Drop-in Node-compatible runtime (built on JavaScriptCore, implemented in Zig).
- **Package manager**: `bun install` is significantly faster than npm/yarn. Lockfile is `bun.lock` (text) by default in current Bun; older versions used `bun.lockb` (binary).
- **Bundler**: Built-in bundler and transpiler for apps and libraries.
- **Test runner**: Built-in `bun test` with Jest-like API.
**Migration from Node**: Replace `node script.js` with `bun run script.js` or `bun script.js`. Run `bun install` in place of `npm install`; most packages work. Use `bun run` for npm scripts; `bun x` for npx-style one-off runs. Node built-ins are supported; prefer Bun APIs where they exist for better performance.
**Vercel**: Set runtime to Bun in project settings. Build: `bun run build` or `bun build ./src/index.ts --outdir=dist`. Install: `bun install --frozen-lockfile` for reproducible deploys.
## Examples
### Run and install
```bash
# Install dependencies (creates/updates bun.lock or bun.lockb)
bun install
# Run a script or file
bun run dev
bun run src/index.ts
bun src/index.ts
```
### Scripts and env
```bash
bun run --env-file=.env dev
FOO=bar bun run script.ts
```
### Testing
```bash
bun test
bun test --watch
```
```typescript
// test/example.test.ts
import { expect, test } from "bun:test";
test("add", () => {
expect(1 + 2).toBe(3);
});
```
### Runtime API
```typescript
const file = Bun.file("package.json");
const json = await file.json();
Bun.serve({
port: 3000,
fetch(req) {
return new Response("Hello");
},
});
```
## Best Practices
- Commit the lockfile (`bun.lock` or `bun.lockb`) for reproducible installs.
- Prefer `bun run` for scripts. For TypeScript, Bun runs `.ts` natively.
- Keep dependencies up to date; Bun and the ecosystem evolve quickly.
