Thinking in React: Static Versions
Static Versions

This module looks at static versions in React, Props, and Mock Components to use when testing an application.

Learning Objectives 

The objectives of this module are to provide you with an understanding of: 

  • How to be able to build a static version of an application
  • How to use Props in components
  • How to be able to test Component snapshots and Components with props
  • How to be able to Mock components when testing

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. 


We welcome all feedback and suggestions - please contact us at to let us know what you think. 


Once we have the component hierarchy outlined, we can build a version that takes our data model and renders it without interactivity. Decoupling the view and interactivity is good as static versions are lots of typing and little thinking and vice versa. The established best practice is to build components that reuse other components and pass data using props. 

We won't be using state here because that's used for interactivity. A top-down approach to building our components is as acceptable as a bottom-up approach. Although this bottom-up approach is more common in TDD environments. Doing all this helps to establish a library of reusable components to render each data model from, each component only has a return JSX expression and any minimal logic to help create it. 

To effectively do this, you need to understand what props are and the mechanisms that are used to pass props down the component tree. It would also be handy to know about default props and how we can type safe and validate props and components using prop tights. If you're not familiar with these ideas, I suggest skills on props using our learning materials before continuing with the thinking in reality.
