React allows you to build UIs virtually, without directly operating through a DOM. It uses the concept of a virtual DOM, which is essentially a copy of the original DOM kept in the memory and synced with the real DOM through a library such as ReactDOM.
React is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It is maintained by Meta and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications.
Like every other good programming library, React makes extensive use of design patterns to provide developers a powerful tool. By properly following the React philosophy, developers can produce some extraordinary applications.
To communicate between two independent components in React, you have the flexibility to set up a global event-driven system, or a PubSub system. An event bus implements the PubSub pattern and allows you to listen and dispatch events from components.
Step 1: Break The UI Into A Component Hierarchy
Step 2: Build A Static Version in React
Step 3: Identify The Minimal (but complete) Representation Of UI State
Step 4: Identify Where Your State Should Live
Step 5: Add Inverse Data Flow
And That’s It
The first thing you’ll want to do is to draw boxes around every component (and subcomponent) in the mock and give them all names.
Now that you have your component hierarchy, it’s time to implement your app. The easiest way is to build a version that takes your data model and renders the UI but has no interactivity.
To make your UI interactive, you need to be able to trigger changes to your underlying data model. React achieves this with state.
Hopefully, this gives you an idea of how to think about building components and applications with React. While it may be a little more typing than you’re used to, remember that code is read far more than it’s written, and it’s less difficult to read this modular, explicit code.
