🧰 AngularJS UI Libraries: Angular Material, PrimeNG, RxJS – Enhance Your UI/UX (2025 Guide)

🧲 Introduction – Why Use UI Libraries in AngularJS?

While AngularJS (1.x) doesn’t offer a component-based system like Angular 2+, it can still be extended using powerful third-party UI libraries like:

• Angular Material – Material Design components
• PrimeNG – Rich UI widgets and forms (legacy AngularJS equivalent: PrimeUI)
• RxJS – Reactive Extensions for real-time data flow (integrated manually)

These libraries help build modern, responsive, and dynamic UIs without reinventing the wheel.

🎯 In this guide, you’ll learn:

• How to integrate Angular Material in AngularJS
• The role of PrimeUI for AngularJS apps
• Using RxJS to create reactive UI logic
• Best practices and real-world scenarios

🎨 Angular Material for AngularJS

Angular Material for AngularJS is available as angular-material.

✅ Step 1: Install Angular Material

npm install angular-material

Include dependencies:

<link rel="stylesheet" href="angular-material.min.css">
<script src="angular.min.js"></script>
<script src="angular-animate.min.js"></script>
<script src="angular-aria.min.js"></script>
<script src="angular-messages.min.js"></script>
<script src="angular-material.min.js"></script>

---

✅ Step 2: Define Module Dependencies

angular.module('myApp', ['ngMaterial']);

---

✅ Step 3: Use Material Components

<md-button class="md-raised md-primary">Submit</md-button>

<md-input-container>
  <label>Username</label>
  <input ng-model="user.name">
</md-input-container>

✅ Components like md-button, md-input-container, md-tabs, and md-dialog enhance the UI with Material Design.

💠 PrimeNG / PrimeUI in AngularJS

While PrimeNG is for Angular 2+, PrimeUI was designed for jQuery and AngularJS compatibility.

✅ Using PrimeUI in AngularJS

1. Install PrimeUI:

npm install primeui

2. Load PrimeUI CSS & JS:

<link rel="stylesheet" href="primeui/themes/bootstrap/theme.css" />
<link rel="stylesheet" href="primeui/primeui.css" />
<script src="primeui/primeui.js"></script>

3. Use with AngularJS by wrapping jQuery widgets:

<input type="text" id="calendar">

<script>
  $(function () {
    $('#calendar').puicalendar();
  });
</script>

✅ You can wrap PrimeUI widgets in AngularJS directives for seamless usage.

🔁 RxJS in AngularJS UI

RxJS adds observable streams to AngularJS UIs for handling:

• Autocomplete
• Typeahead
• WebSocket updates
• Button click throttling

✅ RxJS Subject Example

app.factory('ReactiveService', function() {
  const subject = new Rx.Subject();

  return {
    sendData: data => subject.next(data),
    onData: callback => subject.subscribe(callback)
  };
});

app.controller('MainCtrl', function($scope, ReactiveService) {
  ReactiveService.onData(msg => {
    $scope.$apply(() => {
      $scope.output = msg;
    });
  });

  $scope.send = () => {
    ReactiveService.sendData('Clicked at ' + new Date());
  };
});

<button ng-click="send()">Send</button>
<p>{{ output }}</p>

✅ Enables decoupled, stream-based UI logic.

🛠️ Best Practices

✔️ Use Angular Material for structured layouts and responsive forms
✔️ Wrap PrimeUI components as custom AngularJS directives
✔️ Use RxJS to handle async UI interactions or real-time events
✔️ Stick to one primary UI framework to avoid style clashes
✔️ Test for accessibility and mobile responsiveness across libraries

📌 Summary – Recap & Next Steps

Even in AngularJS, modern UI development is possible using Angular Material, PrimeUI, and RxJS. They help build responsive, reactive, and well-styled interfaces while boosting productivity and UX quality.

🔍 Key Takeaways:

• Use angular-material for Material Design UI
• Use PrimeUI for jQuery-based UI widgets
• Use RxJS for reactive user interactions and event handling
• Wrap and modularize 3rd-party components for reusability
• Combine UI libraries with AngularJS best practices

⚙️ Real-world Relevance:
Widely used in enterprise dashboards, admin panels, reporting tools, and data-rich AngularJS platforms that need modern UI/UX.

❓ FAQ – AngularJS UI Libraries

---

❓ Can I use Angular Material with AngularJS 1.x?
✅ Yes. AngularJS has its own version of Angular Material (angular-material) fully compatible with AngularJS 1.3+.

---

❓ What is the PrimeNG alternative for AngularJS?
✅ PrimeUI. It provides UI components compatible with jQuery and can be wrapped inside AngularJS directives.

---

❓ Does RxJS work with AngularJS?
✅ Yes. RxJS can be manually integrated into AngularJS services to support observable streams and reactive logic.

---

❓ Which is better for UI – Angular Material or PrimeUI?
✅ Angular Material offers better integration, accessibility, and native AngularJS directive support compared to PrimeUI.
