Demonstrating Reusable React Components in a Form
2.10.2019
Components are the building blocks of React applications. It’s almost impossible to build a React application and not make use of components. It’s widespread to the point that some third-party packages provide you with components you can use to integrate functionality into your application.
These...
Getting to Know the useReducer React Hook
26.6.2019
useReducer is one of a handful of React hooks that shipped in React 16.7.0. It accepts a reducer function with the application initial state, returns the current application state, then dispatches a function.
Here is an example of how it is used;
const [state, dispatch] = useReducer(reducer...

The Circle of a React Lifecycle
23.4.2019
A React component goes through different phases as it lives in an application, though it might not be evident that anything is happening behind the scenes.
Those phases are:
mounting
updating
unmounting
error handling
There are methods in each of these phases that make it possible to perform...
React 16.6.0 Goodies
23.1.2019
React 16.6.0 was released October 2018 and with it came goodies that spice up the way we can develop with React. We’re going to cover what I consider the best of those new goodies with examples of how we can put them to use in our work.
React.memo() avoids unnecessary re-rendering
There...
Intro to React Hooks
18.1.2019
Hooks make it possible to organize logic in components, making them tiny and reusable without writing a class. In a sense, they’re React’s way of leaning into functions because, before them, we’d have to write them in a component and, while components have proven to be powerful and functional...
Using React Portals to Render Children Outside the DOM Hierarchy
15.1.2019
Say we need to render a child element into a React application. Easy right? That child is mounted to the nearest DOM element and rendered inside of it as a result.
render() {
return (
<div>
// Child to render inside of the div
</div>
);
}
But! What if we want...
Rendering Lists Using React Virtualized
13.12.2018
Working with data in React is relatively easy because React is designed to handle data as state. The hassle begins when the amount of data you need to consume becomes massive. For example, say you have to handle a dataset which is between 500-1,000 records. This can result in massive loads and lead...
Compound Components in React Using the Context API
7.12.2018
Compound components in React allow you to create components with some form of connected state that’s managed amongst themselves. A good example is the Form component in Semantic UI React.
To see how we can implement compound components in a real-life React application, we’ll build a compound...
How React Reconciliation Works
17.5.2018
React is fast! Some of that speed comes from updating only the parts of the DOM that need it. Less for you to worry about and a speed gain to boot. As long as you understand the workings of setState(), you should be good to go. However, it’s also important to familiarize yourself with how this...
