ReactJS is a JavaScript library for building user interface. React allows developers to create large web-applications that use data that can change over time, without reloading the page. It aims primarily to provide speed, simplicity and scalability. React processes only user interfaces in applications. This corresponds to View in the Model-View-Controller(MVC) pattern, and can be used in combination with other JavaScript libraries or frameworks in MVC, such as AngularJS. Several notable features of ReactJS are one-way data flow, JSX, component-based.

Tutorial

ReactJS docs: Before starting on the assignment, please complete the quick start tutorial step by step. The advanced guides and the tutorial are helpful and to master ReactJS you will need to learn these. However, for this module, you are not required to do these parts.

Individual Assignment

In this assignment, you will build a ReactJS restaurant website. To learn ReactJS, please view and complete this quick start tutorial and read the introduction of route carefully. After creation, your app should look like this: 

 my-app/
   README.md
   node_modules/
   package.json
   public/
     index.html
     favicon.ico
   src/
     App.css
     App.js
     App.test.js
     index.css
     index.js
     logo.svg

Let's take a look into the app you have created. package.json is the file that holds various metadata that is relevant to your app. This file is used to give information to npm that allows it to identify the project as well as handle the dependencies to your app. For more information, see the Node.JS guide: Node.JS#Node.js Conventions.

For your app to work, you cannot delete or rename these files:

  • public/index.html
  • src/index.js

Building a React website is similar to playing with LEGOs. public/index.html is analogous to the base LEGO piece, and all the other components you build will be placed in this single div: 

<div id="root"></div>

. You can also include javascript libraries inside the <head> tag.

src/index.js the Javascript entry point for your app. What this file does is to render a component called <App> from App.js in "root" div. You can also render other components.

Creating the Site

Now we are making a restaurant website! Your website will need at least four components, <Header>, <Footer>, <Appetizers>, and <Entrees>. <Header> is your page header, which should include a search bar and a button that can switch between appetizers and entrees pages. <Footer> is your page footer, it can be anything you like. <Appetizers>, and <Entrees> are two pages of your website, each pages will include different food introductions. When you switch between these two pages, you shall not change your page header and footer. Here is what should your page look like:

appetizer page

Once you click the "Entree" button, it will go to the second page.

entree page

At all time, there should be search bar in your page. It can dynamically displays the search results. For example:

entree page

We have provided the following data. This will be your "database". 

 var PRODUCTS = [
       {name: 'Sliced Beef Tripe in Chili Oil With Peanuts',
        description: 'Served cold or at room temperature, which is made of thinly sliced beef and beef offal.Common ingredients in the modern version include beef heart, tongue and tripe, and a generous amount of various spices, including 
                             Sichuan pepper. ', 
        price: '$4.99'},
        {name: 'Mung Bean Jelly With Numbing-Hot Sauce',
         description: 'Starch jelly that is usually served cold, with a savory sauce.', 
         price: '$9.99'},
        {name: 'Dandan Noodle',
         description: 'It consists of a spicy sauce containing preserved vegetables (often including lower enlarged mustard stems, or upper mustard stems), chili oil, Sichuan pepper, minced pork, and scallions served over noodles.', 
         price: '$10.99'},
        {name: 'ChongQing Noodle Soup',
         description: 'a bowl of hot noodles served in a thin but flavorful broth flavored with Sichuan pepper and chili oil, topped with sesame seeds and a bit of steamed cabbage.', 
         price: '$19.99' },
        {name: 'Chengdu-Style Bing',
         description: 'The bread in these sandwiches is vaguely similar to the more common Xian or Beijing-style bing, but quite a bit crisper, puffier, and frankly, better.',
         price: '$8.99'},
        {name: 'Sour and Hot Glass Noodles',
         description: 'This is almost the sister dish of Chongqing noodles,this used for this snack is thick sweet potato noodles, which is much chewier than common noodles', 
         price: '$19.99'}
