Configuration

Project Structure

│   └── about.jsx
├── components/
│   └── Button.jsx
├── styles/

Server Islands 🏝️

Add static content that renders at build time:

// pages/about.jsx
export const render = "server"; // 🏝️ This marks a Server Island

export default function About() {
  return (
    <div>
      <h1>About Us</h1>
      <p>This content is pre-rendered as static HTML!</p>
      <a href="/">Go home</a>
    </div>
  );
}

Rules for Server Islands:

• ✅ Pure static JSX only
• ❌ No React hooks (useState, useEffect, etc.)
• ❌ No browser APIs (window, document, fetch)
• ❌ No event handlers (onClick, onChange, etc.)
• ❌ No Link component (use <a> tags instead)

Integration with BertUI

Ernest replaces BertUI's build system. Update your package.json:

{
  "scripts": {
    "dev": "ernest dev --mode ui",
    "build": "ernest build --mode ui"
  },
  "dependencies": {
    "ernest": "latest"
  }
}

Migration from BertUI

# In your BertUI project
bunx ernest migrate

This will:

1. Add Ernest dependency
2. Update package.json scripts
3. Create ernest.bundler.js
4. Preserve your existing config
