In AngularJS, you can dynamically build routes at runtime based on a JSON configuration by utilizing the $routeProvider and $route services. The idea is to iterate through the JSON configuration, define routes, and set up the necessary route handlers accordingly.

Here's a step-by-step guide to achieving this:

  1. Create a JSON Configuration: Start by defining a JSON configuration that contains the route details. For example:

    // routes.json [ { "path": "/home", "templateUrl": "partials/home.html", "controller": "HomeController" }, { "path": "/about", "templateUrl": "partials/about.html", "controller": "AboutController" }, { "path": "/contact", "templateUrl": "partials/contact.html", "controller": "ContactController" } ]
  2. Load the JSON Configuration: In your application, load the JSON configuration using an HTTP request or any other method to get the JSON data into your application.

  3. Configure the Routes Dynamically: In your AngularJS application's configuration block (usually defined in app.js), configure the routes dynamically based on the loaded JSON configuration.

    // app.js var app = angular.module('myApp', ['ngRoute']); app.config(function($routeProvider) { // Load the JSON configuration (replace this with your own method to load the JSON) var jsonConfig = [ { "path": "/home", "templateUrl": "partials/home.html", "controller": "HomeController" }, { "path": "/about", "templateUrl": "partials/about.html", "controller": "AboutController" }, { "path": "/contact", "templateUrl": "partials/contact.html", "controller": "ContactController" } ]; // Loop through the JSON configuration and define routes dynamically angular.forEach(jsonConfig, function(route) { $routeProvider.when(route.path, { templateUrl: route.templateUrl, controller: route.controller }); }); // Define a default route $routeProvider.otherwise({ redirectTo: '/home' }); });

    In this example, we loop through the jsonConfig array and use the $routeProvider.when() method to define routes dynamically based on the JSON configuration.

  4. Set Up Controller and Partials: Make sure you have defined the corresponding controllers (e.g., HomeController, AboutController, ContactController) and partial HTML templates (e.g., partials/home.html, partials/about.html, partials/contact.html) for each route.

With this setup, your AngularJS application will dynamically build the routes at runtime based on the JSON configuration, and the corresponding controllers and templates will be loaded when the user navigates to different paths.

Remember to replace the jsonConfig array with your own method to load the JSON configuration data. Additionally, ensure that your AngularJS application includes the required modules (e.g., ngRoute) and that the necessary files (controllers and partials) are available in your application.
