Ever tried interacting with a GraphQL server in a client-side application and felt like giving up even before getting anywhere? Ever declined an invitation to join a code base that requires working with GraphQL API because you had no idea? Ever felt like the only front-end engineer who hasn’t learned how to consume GraphQL APIs? If you answered yes to any of these questions, then this tutorial is for you. We’ll be taking a closer look at a few basics of GraphQL and Apollo Client, as well as how to work with both of them. By the end, we’ll have built a pet shop app that uses Apollo Client. Then, you can go on to build your next project.

Styled components are “visual primitives for components”, and their goal is to give us a flexible way to style components. The result is a tight coupling between components and their styles. While the component-driven approach has ushered in a new frontier in the way we build web applications, it isn’t without its imperfections — one being its usability and scalability with CSS. This has given birth to a new way to construct and manage our styles in a component-specific manner, otherwise knows as CSS-in-JS.

Since React was introduced, it has transformed the way front-end developers build web applications, and its virtual DOM is famous for effectively rendering components. In this tutorial, Shedrack Akintayo will discuss various methods of optimizing performance in React applications, and also the features of React that we can use to improve performance.

There is a high possibility that a lot of components in your React application will have to make calls to an API to retrieve data that will be displayed to your users. It’s already possible to do that using the componentDidMount() lifecycle method, but with the introduction of Hooks, you can build a custom hook which will fetch and cache the data for you. That’s what Ademola Adegbuyi will cover with this tutorial.

Gatsby is a modern static-site generator that has revamped the way static websites are being built. It incorporates React, Node.js, and GraphQL to create stunning and blazing-fast websites. In this post, Aleem Isiaka will introduce Gatsby plugins, discuss the types of Gatsby plugins that exist, differentiate between the forms of Gatsby plugins, and, finally, create a comment plugin that can be used on any Gatsby website, one of which you will install by the end of the tutorial.

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.

Building a well-functioning application requires good testing; otherwise, knowing whether your application works as expected would be a matter of guesswork and luck. Jest is one of the best tools available for testing React applications. In this article, Adeneye David Abiodun will show you everything you need to create a solid test for your React components and application.

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.
