🌐 AppML API & References – Extend Functionality with Scripting and Modular Components

🔧 Introduction – Extend AppML with APIs and Reusable Logic

AppML isn’t limited to declarative data binding—it also offers an API for programmatic control, empowering developers to dynamically load models, run logic, or inject custom functions directly into the MVC cycle. Whether you’re handling data updates or building reusable blocks, AppML’s API enables modular design without complex JavaScript setups.

You’ll also gain access to the official AppML reference manual, essential API functions, and best practices for creating clean, maintainable AppML-based projects.

✅ The AppML API allows developers to create interactive, scalable, and maintainable web apps using simple, script-enhanced HTML.

🎯 What You’ll Learn in This Section

• 🧰 How to use the AppML API for data and controller interaction
• 📘 Where to find official AppML documentation
• 🧠 How to write custom functions for enhanced interactivity
• ♻️ Techniques to design and reuse modular components

📘 Topics Covered

🧰 AppML – API Overview

AppML provides JavaScript-style API access within HTML. You can control app behavior using:

myApp = new AppML();
myApp.load("model.json");

✅ This lets you dynamically load and control data from scripts or event triggers.

🧪 AppML – Common API Methods

Most-used methods include:

✅ These are helpful when you need real-time model control without writing full JavaScript apps.

📘 AppML – AppML Reference Manual

The full official AppML documentation is available on W3Schools and includes:

• Tag definitions (<appml-data>, <appml-controller>)
• Attribute usage
• Supported file formats
• Controller logic and syntax

🧠 AppML – Custom Functions with API

You can inject your logic using the AppML API by defining a controller in your HTML:

<div appml-controller="myController()"></div>

<script>
function myController(app) {
  app.model.property = "Hello World";
  app.run();
}
</script>

✅ This lets you enhance interactivity without complex JavaScript frameworks.

♻️ AppML – Reusable Component Creation

Combine models, views, and templates to make modular HTML components:

<appml-data model="components/header.json"></appml-data>

✅ Use templates and includes to create sections like headers, footers, cards, or list blocks.

📌 Summary – Recap & Next Steps

The AppML API bridges the gap between low-code and full control. Whether loading data or injecting logic, you can build responsive, scalable applications that are modular and easy to maintain—all with minimal scripting.

🔍 Key Takeaways:

• Use AppML methods like load() to dynamically control data
• Reference official documentation to explore deeper usage
• Create modular components with templates, models, and controllers
• Bind custom functions to enhance logic and workflows

⚙️ Real-World Relevance:
Ideal for developers building admin dashboards, catalogs, or interactive interfaces without JavaScript complexity.

❓ FAQs

❓ Can I use AppML API with external JavaScript files?
✅ Yes, AppML APIs can be accessed from any <script> block, including external JS files.

❓ What is the difference between load() and run()?
✅ load() fetches the model or data source, while run() executes the controller logic tied to the AppML instance.

❓ Is the AppML API compatible with modern browsers?
✅ Yes, AppML is designed to run smoothly in all modern browsers including Chrome, Firefox, Edge, and Safari.
