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.

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.

Building a React website is similar to playing with LEGOs. 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>

Now take a look at src/index.js. What this file does is to render a component called <App> from App.js in root div.


After creating a new React application, you will only need to modify the files in src folder and the <title> tag in /public/index.html
