How to Use AngularJS For Web Development in 2021?
To use AngularJS development services is quite easy for web developers. A website design company can develop an app in no time by creating a code for your HTML scripts.
Steps:
Include the “ng-app” directive in the <html> tag. It’ll make AngularJS run on the page, defining the page as an Angular application.
<html lang=”en” ng-app>
Place the Angular <script> tag at the bottom of your page, where the <head> tag ends.
<script src=”lib/angular/angular.js”></script>
Add regular HTML. HTML attributes are used to access AngularJS directives, while evaluation of expressions is done with double-bracket notation.
<body ng-controller=”TasksListCtrl”>
<h1>Today’s tasks</h1>
<ul>
<li ng-repeat=”tasks in tasks”>
{{task.name}}
</li>
</ul>
</body>
</html>
Here, the directive ng-controller defines a namespace. You can replace it with your AngularJS controller to control the data and evaluate the expressions in your HTML. While the ng-repeat directive is an Angular repeater object, which asks Angular to create list elements as long as you have tasks to display.
In spite of having various frameworks, AngularJS has compelling features that are helpful for developers and designers as well.

AngularJS allows for an immediate synchronization between the view and the model. So, if you change View data, the model will automatically be revised. Simply put, using this two-way data binding, the app will significantly simplify its presentation layer. This allows a simpler, less intrusive approach to DOM display to construct the UI.

However, dependency injection allows developers to request for the dependencies instead of doing it by themselves. By using it, AngularJS caters traditional server-side services to client-side web apps. This leads to making an app much lighter.
So, if you want to gain access to core AngularJS web app development services, then you need to pass a particular service as a parameter. Therefore, as a result, AngularJS will identify that you want to use that service and will make an instance available for you.
function EditCtrl($scope, $location, $routeParams) {
// Write something here…

angular.
module(‘MyServiceModule’, []).
factory(‘notify’, [‘$window’, function (win) {
return function (msg) {
win.alert(msg);
};
}]);
function myController(scope, notifyService) {
scope.callNotify = function (msg) {
notifyService(msg);
};
}
myController.$inject = [‘$scope’, ‘notify’];
Templates
The HTML template of AngularJS has Angular-specific attributes and elements. By combining the template with information from the controller and model, AngularJS renders the dynamic view in browsers.
Here are some of the Angular elements and attributes that can be used:
Filter: It formats the data to display.
Form Controls: It’s used for user input validation.
Markup: Using double curly brace notation {{ }}, you can bind expressions to elements.
Directive: It renders a reusable DOM component or elongates an existing DOM element.

<html ng-app>
<!– Body tag augmented with ngController directive –>
<body ng-controller=”MyController”>
<input ng-model=”foo” value=”bar”>
<!– Button tag with ng-click directive, and

wrapped in “{{ }}” markup –>
