🚀 INSTALLATION

# In your Bertui project
npm install bertui-pagebuilder

# Or clone standalone
git clone https://github.com/bertui/pagebuilder
cd bertui-pagebuilder
bun install

📦 QUICK START

1. Create `bertui.config.js`

// bertui.config.js
export default {
  pageBuilder: {
    sources: [
      {
        name: "my-blog",
        endpoint: "https://api.example.com/posts",
        headers: {
          "Authorization": "Bearer YOUR_TOKEN"
        },
        method: "GET",
        template: "./templates/blog-post.jsx",
        output: "./pages/blog/[slug].jsx",
        dataStructure: {
          array: "data.posts",
          item: {
            slug: "slug",
            title: "title",
            content: "body.html",
            author: "author.name",
            date: "published_at"
          }
        },
        fallback: "NULL"
      }
    ]
  }
};

2. Create Template

// templates/blog-post.jsx
export default function BlogPost() {
  return (
    <article>
      <h1>{title}</h1>
      <div className="meta">
        <span>By {author}</span>
        <time dateTime="{date}">{new Date(date).toLocaleDateString()}</time>
      </div>
      <div dangerouslySetInnerHTML={{ __html: content }} />
      <footer>
        <p>Slug: {slug}</p>
      </footer>
    </article>
  );
}

3. Run It!

# Generate pages
bun run pagebuilder

# Build with Bertui
bun run build

🎨 TEMPLATE WRITING GUIDE

📝 The Golden Rules

1. Variables: Use `{curlyBraces}` NOT `${dollarBraces}`

// ✅ CORRECT
<h1>{title}</h1>
<p>{content}</p>

// ❌ WRONG  
<h1>${title}</h1>
<p>${content}</p>

2. Attributes: Use Quotes `" "` Around Variables

// ✅ CORRECT - quotes around {date}
<time dateTime="{date}">{new Date(date).toLocaleDateString()}</time>
<img src="{imageUrl}" alt="{altText}" />

// ❌ WRONG - no quotes
<time dateTime={date}>...</time>    // Becomes: dateTime=2024-01-01 (invalid!)
<img src={imageUrl} alt={altText} /> // Becomes: src=https://... (might work but risky)

3. Conditional Rendering: JavaScript Expressions Stay `{ }`

// ✅ CORRECT - JavaScript inside { }
{excerpt && <p className="excerpt">{excerpt}</p>}
{tags?.length > 0 && (
  <div className="tags">
    {tags.map(tag => <span key={tag}>{tag}</span>)}
  </div>
)}

// These {tags} and {excerpt} WON'T be replaced - they're JS expressions!

4. HTML Content: Use `dangerouslySetInnerHTML` for HTML

// ✅ CORRECT
<div dangerouslySetInnerHTML={{ __html: content }} />

// The {content} here refers to the JS variable, not template replacement

📊 Template Examples

Simple Blog Post

export default function BlogPost() {
  return (
    <article>
      <h1>{title}</h1>
      <div className="meta">
        <span>By {author}</span>
        <time dateTime="{date}">{new Date(date).toLocaleDateString()}</time>
      </div>
      <div className="content">
        {content}
      </div>
    </article>
  );
}

E-commerce Product

export default function Product() {
  const isOnSale = parseFloat(price) < parseFloat(originalPrice);
  
  return (
    <div className="product">
      <img src="{image}" alt="{name}" />
      <h2>{name}</h2>
      
      <div className="pricing">
        {isOnSale && (
          <>
            <span className="original-price">${originalPrice}</span>
            <span className="sale-badge">SALE</span>
          </>
        )}
        <span className="price">${price}</span>

      <h1>{fullName}</h1>
      <p className="username">@{username}</p>
      
      {bio && <p className="bio">{bio}</p>}
      
      <div className="stats">
        <div className="stat">
          <strong>{postCount}</strong>
          <span>Posts</span>
        </div>
        <div className="stat">

          <span>Followers</span>
        </div>
      </div>
      
      {website && (
        <a href="{website}" className="website" target="_blank" rel="noopener">

        </a>
      )}
    </div>

📚 RECIPES

Recipe 1: Blog with Comments

// Fetch posts
{
  endpoint: "https://api.example.com/posts",
  template: "./templates/post-with-comments.jsx",
  output: "./blog/[slug].jsx",
  dataStructure: { /* post fields */ }
}

// Fetch comments (separate source)
{
  endpoint: "https://api.example.com/comments?post={slug}",
  template: "./templates/comments.jsx",
  output: "./blog/[slug]/comments.jsx",
  dataStructure: { /* comment fields */ }
}

Recipe 2: Multi-language Site

sources: [
  {
    name: "posts-en",
    endpoint: "https://api.example.com/posts?lang=en",
    output: "./en/blog/[slug].jsx",
    // ...
  },
  {
    name: "posts-es",
    endpoint: "https://api.example.com/posts?lang=es",
    output: "./es/blog/[slug].jsx",
    // Same template, different data!
  }
]

Recipe 3: API Proxy with Transformation

// Custom server that transforms API response
import { serve } from 'bun';

serve({
  port: 3001,
  async fetch(req) {
    // Fetch from real API
    const response = await fetch('https://real-api.example.com', {
      headers: req.headers
    });
    
    // Transform to PageBuilder format
    const data = await response.json();
    const transformed = {
      posts: data.items.map(item => ({
        slug: item.id,
        title: item.name,
        // ... transform fields
      }))
    };
    
    return new Response(JSON.stringify(transformed));
  }
});
