ng-xtend Framework

Empower your Angular applications with a flexible, scalable plugin ecosystem! 🚀

💡 Why ng-xtend?

The most successful web platforms—like WordPress, Nextcloud, or Drupal—thrive because of their massive plugin ecosystems. They make it effortless to extend functionality without touching the core.

In the Angular & TypeScript world, achieving this level of modularity has always been a challenge. ng-xtend was built to bridge that gap. It allows you to build “extensible by design” applications where external teams can contribute features seamlessly.

✨ Key Features

ng-xtend is an Angular library that enables you to:

• 🧩 Define once, render anywhere: Focus on your data structures; let plugins handle the UI.
• ⚡ Dynamic Loading: Load and install plugins at runtime—no rebuild required.
• 💾 Storage Agnostic: Save, load, and update data to any backend or storage.
• 🔌 Seamless Interop: Plugins work together intelligently, even without knowing each other exists.

🛠️ Supported Plugin Types

Currently, ng-xtend supports four major extension points:

🚀 How it Works (The Magic)

The host application doesn’t need to know its plugins at compile time. It simply sets Render Points (xt-render):

1. Configuration: A simple JSON file defines which plugins to load from which remote URLs.
2. Registration: Upon loading, the plugin registers itself and declares which data types or actions it supports.
3. Resolution: When ng-xtend encounters a specific type (e.g., Rating, Currency), it automatically finds and injects the correct component from the loaded plugins.

🗺️ Roadmap

• Dynamic insertion of simple components
• Plugin registry system
• Support for complex components and lists
• Strong type support
• Remote dynamic loading
• Action components support
• v1.0 Release! 🏁
• Enhanced component selection (context-aware)
• v2.0 & beyond

🧑‍💻 Getting Started

Developing a Plugin

We use a monorepo structure powered by Rush.

npm install -g @microsoft/rush
rush update
rush build

News

• 2026-01-04: Version 0.5.5, supports for many to one references
• 2025-11-02: Added support for actions, allowing plugins to add features dynamically, and added the agenda plugin, with support for recurrent tasks
• 2025-09-06: Version 0.5, moved to Angular 20.2, added country selection plugin.
• 2025-08-24: Published of apps developed: Dashboard
• 2025-07-14: First release, with support for dynamic plugins (thanks to Angular architects!) and a few plugins for Financial, Web and International applications. As well, added a default plugin to edit any data.

Some examples ?

Here are screenshots of an application automatically handling list, view and edition of complex data (evaluations of coffee beans) using ng-xtend, a dont-code application, and the default plugin and web plugin
You can see how the different plugins work together without knowing each other. Even the host application does not know them.

Detailed plugin development guide

1. Checkout the repository ng-xtend
2. It’s a monorepo using rush build system, so run

    npm install -g @microsoft/rush
    rush update
    rush build

3. Use a copy of libs/xt-plugin-sample to develop your own plugins and components.
4. Unit test your components using vitest
   • ng-xtend provides pre-defined test pages for different cases (in a form or not) that will easily embed your component for testing
   • See currency simple component test
   • Or money complex component test
5. Test your components using plugin-tester
   • More details in plugin-tester user documentation.
   • Run your plugin tester application, for example ng serve sample-tester for the sample plugin
   • Run the xt-plugin-tester with ng serve plugin-tester in xt-plugin-tester directory
   • In the Plugin Tester app, load your plugin by entering its url (http://localhost:4201 for sample plugin) in the Plugin url field.
   • Once loaded, go to the test screen, select your component in the second screen, and play with it
   • For easier debugging, you can statically add and register your plugin to xt-plugin-tester/package.json

Use plugins in my application

To use ng-xtend plugins in your own Angular Application, xt-host project is a great example. It does:

• Install xt-components and the default plugin in your package.json

    npm install xt-components xt-type xt-store
    npm install xt-plugin-default

• Configure your application to load your plugins.

    protected resolverService = inject (XtResolverService);
    this.resolverService.loadPlugin(url);

The plugins will register themselves automatically.

• Describe the data type you want to manipulate

    this.resolverService.registerTypes ({
      money:{
        amount:'number',
      currency:'currency'  /** Type provided by the finance plugin **/ 
    },
      book: {
        name:'string',
        publication:'date',
        price:'money',
        notation:'rating'  /** Type provided by the web plugin **/
      }    
    }); 

• Sets insertion point in your angular pages
  • For example, to display a table of books

        <h1>List of books</h1>
        <xt-render [displayMode]="LIST_VIEW" [valueType]="book" [value]="listOfBooks" ></xt-render>

 - or allow editing a book information

        <h1>Enter your book details</h1>
        <div form="bookForm">
          <xt-render [displayMode]="FULL_EDITABLE" [valueType]="book" [formGroup]="bookForm" subName="book"></xt-render>
        </div>

 - To support more complex scenario, use

       <xt-render-sub [context]="context()"></xt-render-sub>

with `context ()` returning type information necessary to select the right component.
