Testing gives confidence in written code. In the context of this article, ‘testing’ means ‘automated testing’. Without automated testing, it is significantly harder to ensure the quality of a web application of significant complexity. Fails caused by automated testing may lead to more bugs in production. In this article, Chidi Orji is going to show you how React developers can quickly start testing their app with the React Testing Library (RTL).

In this tutorial, Chidi Orji will show you how to work with Firebase push notifications in the backend and frontend. We’ll set up the notifications system with an Express back-end server. Afterwards, you’ll listen for the notifications in a React front-end app. You will implement the backend first, then move on to the frontend. In that way, you can use whichever section appeals more to you. So let’s get started.

Front-end developers and designers create amazing static assets for web applications. Today, Philip Kiely will be focusing on what happens after the style hotfix or beautiful graphic you just finished is pushed to master. He’ll also investigate handling files that users upload, called media files. Together, you’ll develop an intuition for the strategies available to Django developers for serving these files to users worldwide in a secure, performant, and cost-effective manner.

In this article, we’re going to learn how to use Immer to write reducers. When working with React, we maintain a lot of state. To make updates to our state, we need to write a lot of reducers. Manually writing reducers results in bloated code where we have to touch almost every part of our state. This is tedious and error-prone. In this article, Chidi Orjil going to see how Immer brings more simplicity to the process of writing state reducers.

In this article, Adeneye David Abiodun explains how to build a facial recognition web app with React by using the Face Recognition API, as well as the Face Detection model and Predict API. The app built in this article is similar to the face detection box on a pop-up camera in a mobile phone — it’s able to detect a human face in any image fetched from the Internet. Please note that you will need to know the fundamentals of React.

To make the move from “site” to app, we’ll need to dive into the world of “app-generated” content. In this article, Bryan Robinson will get you started in this world with the power of serverless data. He’ll start with a simple demo by ingesting and posting data to FaunaDB and then extend that functionality in a full-fledged application using Auth0, FaunaDB’s Token system and User-Defined Functions.

In this article, Chidi Orji will explore the concept of error boundaries in a React application. You’ll work through an example app to see how we can use error boundaries to deliver a better app experience. Finally, you’ll integrate Sentry into our error boundary for realtime error reporting. The only prerequisite is that you have some familiarity with React class components. Let’s dig in!
