$stateProvider

The $stateProvider is part of the ui-router library, which offers more advanced routing features compared to ngRoute. It allows for complex and nested routing configurations, enabling the creation of State-Based Routing Hierarchies. This is particularly useful for large and complex applications where routes can have multiple views and states. The $stateProvider provides a powerful and flexible way to manage different states of your application, making it a better choice when you need more advanced routing capabilities and state management.

Syntax

var app = angular.module('myApp', ['ui.router']);
app.config(function ($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise('/defaultPath');
    $stateProvider
        .state('stateName', {
            url: '/statePath',
            templateUrl: 'template.html',
            controller: 'ControllerName'
        });
});

Example: The below example demonstrates the usage of $stateProvider in AngularJS. Here, we have defined three states (‘dsa’, ‘fullstack’, and ‘ai’) and display content for each state in a <div ui-view> element when the user clicks on the respective images.

Output:

In AngularJS, as we create Single-Page Applications, we need to implement the routing of components to view those images without having full page reloads. This can be achieved with the most popular routing methods, i.e., $routeProvider (ngRoute) and $stateProvider (ui-router).

In this article, we will explore the $routeProvider and $stateProvider in AngularJS and understand their basic implementation with the help of examples, along with knowing the difference between these two methods
