🚀 Getting Started with AppML – Build Your First Data-Driven Web App Without JavaScript
✨ Introduction – Build Your First AppML Application
AppML makes it incredibly easy to create dynamic web applications using just HTML and structured data like JSON or XML—no JavaScript required. It uses declarative syntax to bind data directly into your HTML, letting you focus on content and structure instead of scripting.
✅ In just a few lines, you can create a fully functional app interface that fetches and displays data dynamically. AppML is ideal for beginners, students, and developers building prototypes or dashboards.

🧪 AppML – First Application
Start by creating a simple HTML file and include the AppML library:
<!DOCTYPE html>
<html>
<head>
<script src="https://www.w3schools.com/appml/2.0.3/appml.js"></script>
</head>
<body>
<div appml-data="customers.json"></div>
</body>
</html>
🔹 This file will automatically load data from customers.json and render it into the <div>.
👋 AppML – Hello World Example
You can render static data directly without external files:
<div appml-data='{"records":[{"message":"Hello, AppML World!"}]}'>
<h2>{{message}}</h2>
</div>
💡 AppML replaces {{message}} with the value from the JSON object in real-time.
🧱 AppML – Basic AppML Structure
An AppML app typically includes:
- A model or data source (
appml-data) - HTML templates using placeholders like
{{}} - Optional controllers or logic extensions
📌 This structure keeps data, view, and logic cleanly separated and easy to manage.
🐞 AppML – Common Errors & Debugging
Common issues include:
- ❌ Wrong path in
appml-data - ❌ Missing or incorrect JSON format
- ❌ Placeholders not matching JSON keys
✅ Always validate JSON structure, check for typos, and test with browser dev tools.
📌 Summary – Recap & Next Steps
AppML offers a quick and code-light way to start building web apps. You can go from setup to a working dynamic page in minutes, using nothing but HTML and structured data.
🔍 Key Takeaways:
- Create functional apps without JavaScript
- Use
<div appml-data="...">to bind data into views - Debug common issues by verifying paths and JSON format
⚙️ Real-World Relevance:
Perfect for educational tools, dashboards, internal tools, and prototypes, AppML lets you build and iterate fast.
❓ FAQs
❓ Can I use AppML with just HTML and no backend?
✅ Yes! AppML can fetch and display data from static JSON or XML files, no backend required.
❓ What happens if the JSON file has a syntax error?
