Search Interface with React js We’ll place a new index.html file inside the public folder that QEDServer created for us when we started it up. In this file, we place our usual HTML skeleton and a element that will hold our application. We’ll tell React to render its contents into this area of the page. We also import a few libraries in the header section of the page: react/index.html ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​Product Search​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​Waiting…​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ We’re including React, but we’re going to use jQuery for making our Ajax requests. React is purely a UI library; it doesn’t have its own way of fetching data from servers. The third library we’re loading is React’s JSX Transformer.

In search.js, we create the initial version of our ProductSearch component: react/search.js ​ ​var​ ProductSearch = React.createCla...

Getting prepared We will utilize the same code that we utilized as a part of the past case as a beginning stage. What’s more, it is suggested that you as of now have Bower introduced on your framework. On the off chance that you don’t have or know Bower, don’t stress, we will exhibit how to introduce it physically. At the root project folder, open your terminal window and type: bower install ngmap --save To get the directive to work properly, you need to add the Google Maps script. In this example, we will use the code directly from the Google CDN through this link: //maps.google.com/maps/api/js. Open the index.html file and add the following script tag right after the mappingService.js script: Add the ng-map script right after the Google Maps script: Don’t place any code inside the tag; when generators run any task, this block of code is always replaced. Open the app.js file and add the following highlighted code to the angularjs dependencies: angular.module('yeomana...
