📂 Case – Introduction to AppML Cases: Learn by Real-World Examples
🧲 Introduction – Why AppML Cases Matter
AppML is a low-code framework designed to make building data-driven web applications fast and simple. But theory alone doesn’t cut it—real-world examples are key to understanding how to use AppML effectively. That’s where AppML Cases come in.
🎯 In this guide, you’ll learn:
- What AppML “cases” are and how they help
- Overview of built-in cases like Customers, Products, and Employees
- Benefits of learning via case-based examples
- How to customize and extend these sample applications
📁 What Are AppML Cases?
AppML Cases are practical, ready-to-run applications that demonstrate how to use AppML with different data sources, models, and controllers. These examples show complete workflows such as:
- Loading data from a JSON or XML file
- Using AppML models for structure and validation
- Displaying and editing records
- Handling sorting, filtering, and form submission
They serve as a starting point for building your own projects.
🧪 Example Case Types
| 🧩 Case Name | 🔍 Description |
|---|---|
| Customers | Manages a customer list using AppML model + JSON data |
| Products | Shows inventory with add/edit/delete using AppML forms |
| Employees | Displays employee directory with advanced filtering |
| Suppliers | Loads and lists supplier info from XML files |
| Shippers | Demonstrates form submissions using PHP/ASP endpoints |
| Text/XML Case | Works with plain files for offline data display |
🔍 How AppML Cases Are Structured
Each case typically consists of:
- HTML File – Defines layout and uses
appml-data,appml-model, and optionalappml-controller - Model File (JSON/XML) – Specifies fields, datatypes, validations, and keys
- Data File (JSON/XML/API) – Supplies the data records to display or manipulate
- Optional Controller – Adds client-side logic like filtering or validation
📄 Sample Case Snippet – Products
<div
appml-model="models/product-model.json"
appml-data="data/products.json"
appml-controller="controllers/product.js">
<h3>Products</h3>
<p>{{name}} – ${{price}}</p>
<button appml-submit>Save</button>
</div>
✅ This simple case handles product listing, editing, and saving—all in one HTML block.
🧠 Why Use AppML Cases?
| 💡 Benefit | ✅ Why It’s Helpful |
|---|---|
| Hands-on learning | Learn by doing, not just reading |
| Modular templates | Reuse parts for real projects |
| Supports low-code development | Ideal for non-programmers too |
| Faster prototyping | Quickly build and test app ideas |
| Covers various data formats | JSON, XML, server APIs |
🧰 Customize AppML Cases
You can extend AppML cases by:
- Changing the data file to connect to your API
- Editing the model to support new fields
- Replacing the controller to apply your business logic
- Styling the UI using custom CSS or frameworks like Tailwind
📌 Summary – Recap & Key Takeaways
AppML Cases are prebuilt learning modules that let you explore AppML’s power by example. From JSON and XML files to backend-driven APIs, these cases show how to build full applications with no JavaScript framework.
🔍 Key Takeaways:
- AppML Cases are real apps: Customers, Products, Employees, and more
- Use them to learn how to integrate models, data, and controllers
- Ideal for beginners, teachers, and prototype builders
- Customizable and extendable for real projects
⚙️ Think of AppML Cases as ready-made app blueprints you can tweak, reuse, or scale.
❓ FAQs – Introduction to AppML Cases
❓ Where can I find AppML sample cases?
✅ Most AppML cases are available in the official AppML repository or course demo kits.
❓ Are these cases production-ready?
⚠️ Not directly. They are meant for learning and prototyping. You should optimize and secure them before deployment.
❓ Can I replace the data source in a case?
✅ Absolutely. Swap out the data URL in appml-data to connect your API or database.
❓ Do I need to modify the model file for every case?
✅ Yes, if your data structure changes. The model should reflect your new fields and data types.
❓ Can I create my own custom case?
✅ Yes! Simply define an HTML file, a model, and data—then wire them using AppML attributes.
