## What it does

The skill hands the agent ready-made patterns for pairing Nuxt 3 with Bun. You get the startup commands (`bunx nuxi@latest init`, `bun install`, `bun run dev`), a script variant with the `bun --bun` flag, and a `nuxt.config.ts` with `nitro.preset: "bun"`. Skip that preset and server imports like `bun:sqlite` fail with `Cannot find bun:sqlite` — worth checking the config when a build complains about the module.

A separate chunk covers the server side: `server/api` routes, middleware, file handling with `Bun.file`, `bun:sqlite` utilities, Nitro plugins and scheduled tasks. There is a table of common errors and a deployment section — building with `NITRO_PRESET=bun`, running `.output/server/index.mjs`, and a Dockerfile based on `oven/bun:1`.

On installing packages the skill is blunt: `bunx nuxi init` downloads and executes remote code. Bun blocks post-install scripts by default, so allow them per package through `trustedDependencies` in `package.json`. It also suggests setting `minimumReleaseAge` in `bunfig.toml` and scoring packages with the Socket CLI. For the full setup it points to the `dependency-upgrade` skill.

## Requirements
- Works with: Docker

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill bun-nuxt -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/bun-nuxt/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/bun-nuxt/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill bun-nuxt -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/bun-nuxt/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill bun-nuxt -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/bun-nuxt/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install secondsky/claude-skills bun-nuxt
```

2. **Manually: put the files in place**
- File: `.github/skills/bun-nuxt/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill bun-nuxt -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/bun/skills/bun-nuxt
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/bun-nuxt/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill bun-nuxt -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/secondsky/claude-skills/tree/HEAD/plugins/bun/skills/bun-nuxt/SKILL.md

## When to use it
- move an existing Nuxt project onto the Bun runtime
- configure the Nitro preset so Bun server APIs work
- wire `bun:sqlite` into server routes and utilities
- build a production Docker image for Nuxt on Bun
- debug errors like `Cannot find bun:sqlite` or `Hydration mismatch`

## Example prompts
- Set up Nuxt 3 on Bun: dev and build scripts with `bun --bun`, Nitro preset `bun`
- Add a server route backed by `bun:sqlite` that returns the user list
- Write a Dockerfile for Nuxt on `oven/bun:1` and run `.output/server/index.mjs`

# Bun Nuxt

Run Nuxt 3 applications with Bun for faster development.

## Quick Start

```bash
# Create new Nuxt project
bunx nuxi@latest init my-app
cd my-app

# Install dependencies
bun install

# Development
bun run dev

# Build
bun run build

# Preview production
bun run preview
```

## Secure Installation

Scaffolding tools like `bunx nuxi init` download and execute remote code. Before running, follow supply chain security best practices:

- **Block post-install scripts** — Bun disables them by default; allow specific packages via `trustedDependencies` in `package.json`
- **Cooldown period** — Configure `minimumReleaseAge` in `bunfig.toml` to wait 7 days for new versions
- **Audit before installing** — Run `socket package score npm <pkg>` or use `socket npm install <pkg>` to check packages

Load the `dependency-upgrade` skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.

## Project Setup

### package.json

```json
{
  "scripts": {
    "dev": "nuxt dev",
    "build": "nuxt build",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "dependencies": {
    "nuxt": "^4.0.0",
    "vue": "^3.5.0"
  }
}
```

### Use Bun Runtime

```json
{
  "scripts": {
    "dev": "bun --bun nuxt dev",
    "build": "bun --bun nuxt build",
    "preview": "bun --bun .output/server/index.mjs"
  }
}
```

## Configuration

### nuxt.config.ts

```typescript
export default defineNuxtConfig({
  // Enable SSR
  ssr: true,

  // Nitro configuration
  nitro: {
    // Use Bun preset
    preset: "bun",

    // External packages
    externals: {
      external: ["bun:sqlite"],
    },
  },

  // Development
  devServer: {
    port: 3000,
  },

  // Modules
  modules: ["@nuxt/ui", "@pinia/nuxt"],
});
```

## Using Bun APIs

### Server Routes

```typescript
// server/api/users.ts
import { Database } from "bun:sqlite";

export default defineEventHandler(async (event) => {
  const db = new Database("data.sqlite");
  const users = db.query("SELECT * FROM users").all();
  db.close();

  return users;
});
```

### Server Middleware

```typescript
// server/middleware/auth.ts
export default defineEventHandler(async (event) => {
  const token = getHeader(event, "Authorization");

  if (!token && event.path.startsWith("/api/protected")) {
    throw createError({
````
