AppML Client-Side Programming – Build Interactive Frontends Without JavaScript

Introduction – Build Dynamic Frontends Using Only HTML

AppML empowers front-end developers to build rich, interactive web applications using nothing but HTML5. With built-in support for data templates, dynamic lists, form validation, and local storage, AppML handles the logic internally—eliminating the need for JavaScript or external frameworks.

Whether you’re creating dashboards, contact forms, or offline apps, AppML makes development faster and cleaner through its declarative structure.

What You’ll Learn in This Section

• How AppML works seamlessly with HTML5
• Using prototypes and templates for UI reuse
• Rendering tables and lists with live data
• Creating and validating forms client-side
• Storing data locally with browser-based storage features

Topics Covered

AppML – Client Overview

AppML runs entirely in the browser, removing the need for backend scripting. Just embed your data sources and HTML structure—AppML handles rendering, filtering, and updating views automatically.

AppML – Using AppML with HTML5

Use semantic HTML5 elements like <section>, <article>, and <template> to build well-structured AppML applications. This ensures maximum compatibility and clean layout design.

AppML – Prototypes and Templates

Define a single template for your UI blocks and reuse it across your application. Great for dynamic cards, lists, or user dashboards.

<template id="userTemplate">
  <li>{{name}} – {{email}}</li>
</template>

AppML – Creating Lists and Tables

You can easily render structured data like:

<appml-data source="users.json"></appml-data>
<ul>
  <li>{{name}} – {{email}}</li>
</ul>

AppML auto-fills the list using the bound data source.

AppML – Forms and Form Validation

Create input forms with AppML bindings like:

<input appml-model="user.name" required>

AppML automatically validates the form based on attributes like required, pattern, and type.

AppML – Local Storage & WebSQL Support

AppML supports localStorage and WebSQL to save user input or session data directly on the browser—useful for offline applications or session retention.

localStorage.setItem("username", "Alex");

Retrieve and display the stored data in your HTML dynamically via AppML.

Summary – Recap & Next Steps

AppML offers powerful client-side programming features using HTML alone. Whether you’re building a simple form or a data-rich application, AppML enables dynamic interaction without writing JavaScript.

Key Takeaways:

• Build interactive frontends using only HTML5 and AppML
• Use templates, prototypes, and dynamic lists to structure your UI
• Validate forms and store user input with built-in browser features
• Create offline-capable applications with local storage/WebSQL

Real-World Relevance:
Ideal for developers building quick dashboards, internal tools, or educational apps without diving into complex JavaScript frameworks.
