The Landscape of Cross-Platform App Development
25.10.2019
I don't track this stuff very well, but I get it. If you want a native app for Android and iOS, it sure would be nice to only have to write it once rather than two very different languages. Roughly double your reach without doubling the work. More and more of these things are reaching into desktop...
Understanding How Reducers are Used in Redux
24.10.2019
A reducer is a function that determines changes to an application’s state. It uses the action it receives to determine this change. We have tools, like Redux, that help manage an application’s state changes in a single store so that they behave consistently.
Why do we mention Redux when talking...
What I Like About Writing Styles with Svelte
23.10.2019
There’s been a lot of well-deserved hype around Svelte recently, with the project accumulating over 24,000 GitHub stars. Arguably the simplest JavaScript framework out there, Svelte was written by Rich Harris, the developer behind Rollup. There’s a lot to like about Svelte (performance, built-in...

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...
A Dark Mode Toggle with React and ThemeProvider
25.9.2019
I like when websites have a dark mode option. Dark mode makes web pages easier for me to read and helps my eyes feel more relaxed. Many websites, including YouTube and Twitter, have implemented it already, and we’re starting to see it trickle onto many other sites as well.
In this tutorial, we’re...
Thinking in React Hooks
25.9.2019
Amelia Wattenberger has written this wonderful and interactive piece about React Hooks and details how they can clean up code and remove all those troubling lifecycle events:
React introduced hooks one year ago, and they've been a game-changer for a lot of developers. There are tons of how-to...
Filtering Data Client-Side: Comparing CSS, jQuery, and React

Say you have a list of 100 names:
<ul>
<li>Randy Hilpert</li>
<li>Peggie Jacobi</li>
<li>Ethelyn Nolan Sr.</li>
<!-- and then some -->
</ul>
...or file names, or phone numbers, or whatever. And you want to filter them...
Web Developer Search History
18.9.2019
Sophie Koonin blogged "Everything I googled in a week as a professional software engineer," which was a fascinating look into the mind of a web developer and what they need to look up during day-to-day work. We all joke that we just Google stuff (or StackOverflow stuff) we don't know off the...
Hamburger Menu with a Side of React Hooks and Styled Components
10.9.2019
We all know what a hamburger menu is, right? When the pattern started making its way into web designs, it was both mocked and applauded for its minimalism that allows main menus to be tucked off screen, particularly on mobile where every pixel of space counts.
CSS-Tricks is all about double...
Model-Based Testing in React with State Machines
4.9.2019
Testing applications is crucially important to ensuring that the code is error-free and the logic requirements are met. However, writing tests manually is tedious and prone to human bias and error. Furthermore, maintenance can be a nightmare, especially when features are added or business logic...
Using requestAnimationFrame with React Hooks
21.8.2019
Animating with requestAnimationFrame should be easy, but if you haven’t read React’s documentation thoroughly then you will probably run into a few things that might cause you a headache. Here are three gotcha moments I learned the hard way.
TLDR: Pass an empty array as a second parameter...

Draggin’ and Droppin’ in React
16.8.2019
The React ecosystem offers us a lot of libraries that all are focused on the interaction of drag and drop. We have react-dnd, react-beautiful-dnd, react-drag-n-drop and many more, but some of them require quite a lot of work to build even a simple drag and drop demo, and some do not provide...
Using Immer for React State Management
7.8.2019
We make use of state to keep track of application data. States change as users interact with an application. When this happens, we need to update the state that is displayed to the user, and we do this using React’s setState.
Since states are not meant to be updated directly (because React’s state...
Fetching Data in React using React Async
1.8.2019
You’re probably used to fetching data in React using axios or fetch. The usual method of handling data fetching is to:
Make the API call.
Update state using the response if all goes as planned.
Or, in cases where errors are encountered, an error message is displayed to the user.
There will always...
Run useEffect Only Once
30.7.2019
React has a built-in hook called useEffect. Hooks are used in function components. The Class component comparison to useEffect are the methods componentDidMount, componentDidUpdate, and componentWillUnmount.
useEffect will run when the component renders, which might be more times than you think....
What I Like About Vue
25.7.2019
Dave Rupert digs into some of his favorite Vue features and one particular issue that he has with React:
I’ve come to realize one thing I don’t particularly like about React is jumping into a file, reading the top for the state, jumping to the bottom to find the render function, then following...
