angularjsHow do I use routing in AngularJS?

Routing in AngularJS is the process of switching views in an application based on certain conditions. It allows us to create single page applications (SPAs) with multiple views.

To use routing in AngularJS, we need to include the ngRoute module as a dependency in our application.

var app = angular.module('myApp', ['ngRoute']);

Then, we need to configure our routes by using the $routeProvider service.

app.config(function($routeProvider) {
  $routeProvider
  .when('/', {
    templateUrl: 'home.html',
    controller: 'HomeController'
  })
  .when('/about', {
    templateUrl: 'about.html',
    controller: 'AboutController'
  })
  .otherwise({
    redirectTo: '/'
  });
});

We can also use the $routeParams service to get the parameters from the current URL.

app.controller('ProductController', function($scope, $routeParams) {
  $scope.productId = $routeParams.productId;
});

Finally, we need to add the <ng-view> directive to our HTML page, so that the views can be loaded into the page.

For more information, see the AngularJS docs.
