🚀 AppML – First Application: Build Your First Dynamic Web App in Minutes

🧲 Introduction – Getting Started with Your First AppML Project

Creating a dynamic web application doesn’t have to be complicated. AppML (Application Modeling Language) empowers developers to build data-driven, interactive HTML applications without needing to write JavaScript. Whether you’re a student, educator, or beginner web developer, your first AppML application can be up and running in minutes.

🎯 In this article, you’ll learn:

How to build your first AppML-powered app
The basic structure of an AppML application
How to load and display data from a JSON file
Best practices for AppML app setup

📁 Folder Setup – Structure Your Project

Before you begin, create a project folder like this:

/first-appml-project
├── index.html
├── data/
│   └── users.json

✅ Required File: appml.js

Include the AppML script in your HTML file by linking:

<script src="https://www.w3schools.com/appml/2.0.3/appml.js"></script>

This script powers all AppML functionality in your browser.

🧪 Step-by-Step: Create Your First AppML App

1️⃣ Create the JSON Data Model

Inside the /data/ folder, add users.json:

[
  { "name": "Alice", "email": "alice@example.com" },
  { "name": "Bob", "email": "bob@example.com" },
  { "name": "Charlie", "email": "charlie@example.com" }
]

This is your Model—the data source AppML will bind to your view.

2️⃣ Write the HTML (View + Data Binding)

Now, create index.html:

<!DOCTYPE html>
<html>
<head>
  <title>My First AppML App</title>
  <script src="https://www.w3schools.com/appml/2.0.3/appml.js"></script>
</head>
<body>

<h2>User Directory</h2>

<div appml-data="data/users.json">
  <h4>{{name}}</h4>
  <p>{{email}}</p>
</div>

</body>
</html>

✅ Here’s what happens:

AppML fetches the users.json model.
It loops through each user.
It replaces {{name}} and {{email}} with actual values.
The output is dynamically rendered without JavaScript!

📺 Expected Output in Browser

User Directory

Alice
alice@example.com

Bob
bob@example.com

Charlie
charlie@example.com

💡 And you didn’t write a single JavaScript loop!

⚙️ Understanding the AppML MVC Structure

🔹 Component	📘 Purpose
`users.json`	Model: The source of structured data
HTML Block	View: Defines how data appears on screen
(Optional) Controller	Logic layer for filtering, validation, etc.

AppML handles the rendering engine internally. All you do is define data and layout.

🧰 Tips for Expanding Your First App

Once you’re comfortable, try:

✅ Loading data from get-users.php (server-side)
✅ Adding filters with a controller file
✅ Displaying tables using <table> + {{fields}}
✅ Styling with CSS

📌 Summary – Recap & Key Takeaways

You’ve just built your first AppML app using only HTML and a JSON file. No JavaScript required, no frameworks to install—just clean, structured code and instant output.

🔍 Key Takeaways:

AppML apps are built with a model (data), a view (HTML), and optional controller
Uses {{}} placeholders to bind data fields to the interface
Perfect for beginners and quick dashboard development
Just include appml.js and you’re ready to build!

⚙️ Your first AppML project is now live—what will you build next?

❓ FAQs – First AppML Application

❓ Do I need a local server to use AppML?
✅ Not for static JSON files. But if you’re working with PHP or databases, a local server like XAMPP or Live Server is required.

❓ What types of data can AppML load?
✅ JSON, XML, and server-side scripts like PHP/ASP that return JSON.

❓ Can I use AppML without a controller?
✅ Yes. Controllers are optional unless you need filtering, validation, or logic-based interaction.

❓ What happens if my JSON path is wrong?
❌ AppML will not display data. Always double-check the path in appml-data.

❓ Can I use AppML for real-time data apps?
✅ Yes, but it depends on how you update the JSON or server data source.
