Description
Learning Path overview
This learning path is a complete guide to building scalable web applications using Facebook’s popular ReactJS library, leveraging the power of a virtual DOM to create fast, fluid UIs.
An overview of the library is given and then a small application is developed using the ‘Thinking in React’ steps recommended by Facebook. Learners will be able to create components to create static versions of applications. Using Props, State (using Hooks) and inverse data flow, a fully functioning application will be created. Techniques to use external data sources is explored, along with relevant lifecycle hooks. Creating a single page application through the use of routing is covered. Finally, state management tools such as Context and Reducers are introduced as a way of handling application data in large scale applications.
Intended Audience
This learning path is aimed at all who wish to learn how to use the ReactJS framework.
Prerequisites of the Course
It is essential you understand the face of contemporary web development to attend this course. We insist upon JavaScript experience, along with good HTML and CSS skills.
Learning Objectives
By the end of the course, you will be able to:
- Create React Components
- Perform some simple tests
- Think in React
- Add state and props to an application
- Add inverse data flow to an application
- Use some common React Hooks
- Use external services to provide data
- Set up a single page application
- Use Context and Reducers

Learning Path Steps
This module will introduce you to the React Development Environment. You’ll also look at some useful tools available in the React environment, as well as looking at a React project anatomy and how React interacts with the DOM.
This module introduces you to some of the basics Components in React and what JSX is.
This lab is designed to build your with ReactJS skills starting from setting up a ReactJS web application and gradually building upon it with new components.
This module introduces you to Thinking in React, and Component Hierarchy in React.
This lab is designed to show you how to create user interfaces using the ReactJS library.
This module looks at more complex data structures, building on what was covered in the intermediate data structures module.
This lab shows you how to install and set up a React-based development environment, allowing you to compile and execute your own React-based web applications.
This module looks at how to identify state in a React application.
This module looks at how to add and update state to a variety of different components
This module looks at Inverse Data Flow in React
Knowledge Check: Event Forms and Inverse Flow
This module looks at how to work with External Data in React. You’ll be looking at Class Components, Effect Hooks, and how to handle data.
This module looks at how to Route in React. You’ll be looking at linking components, creating dynamic links, parameterized routes, and how to install the React Router DOM.
This module looks at how to manage state in React. You’ll be looking at state management, context and reducers.
This module looks at testing in React. You’ll learn how to set up a test environment, Jest, and other useful tools to test your React App.
The objectives of this module are to summarise what you’ve done in this learning path, and provide you with some next steps.
