II Openathon Custom Open Cloud
You are welcome to a new Openathon edition organized for the Accenture Technology Custom Open Cloud community where, once again, we will have the opportunity to discover, in a practical way, the possibilities offered by the different architectures and leading frameworks in the market.
As you already knows, this time we will learn to develop a FrontEnd web application using React. We will also use some of the recommended best practices such as routing, asynchronous REST API access, reusable components and state management.
React’s strongest capability is the creation of web interfaces based on reusable components. Therefore, we are going to create and reuse our own components while learning how to manage their life cycle, the management of props and the JSX syntax while exercising our knowledge of JavaScript (ES6).
What we are going to do
We will learn how to develop a web application using React, playing with props, JSX, Virtual DOM, components, routing, REST API consumption, components reuse… and applying some of the recommended good practices like Single responsibility principle, Isolation, functional programming and prototypal inheritance.
The web application will consist on a Main and two detail pages:
The main page of the application will have this structure:
The main page is a modularized page that takes advantage of many reusable components, whose hierarchy can be seen in the following picture:
To provide data to the page we will also use a mocked REST API endpoint emulating the Accenture site data services:

This installation will also install npm, the package manager for Node.js and the world's largest software registry.
-
Install webpack
Open your terminal or command prompt and run:
npm install webpack -g
webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging. More info.
-
Install json-server
Open your terminal or command prompt and run:
npm install json-server -g
JSON Server is a Node module that can be used to create demo REST web services in a few minutes using a JSON file to provide sample data. We will configure it later.
