React 19 introduces a suite of features that empower developers to build seamless, performant user interfaces. Among these, async transitions stand out as a game-changer for handling asynchronous operations without freezing the UI. This is particularly impactful when building forms where users expect instant feedback, smooth interactions, and no jarring loading states.

React Hooks changed the way we compose components, but testing them can be a mess—especially if you’re using asynchronous data, having side effects that require cleanup logic, or need to check dependencies from React Context. The react-hooks-testing-library (deprecated now in favor of testing-library/react) solves all of these problems, allowing developers to test hooks in isolation, configured for specific behavior.

Creating a modern React application can be intimidating- it’s like building a skyscraper. The finished product can be beautiful, but if a square-foot section of the foundation is weak, you have a big problem. Just like a skyscraper, developers have weak points – those points are bugs. The way the average developer finds bugs today is like trying to find a wire that is faulty by randomly drilling holes into the drywall of a skyscraper. Not very helpful or efficient.

It is said that the special nature of software development is ever-changing so it is important to choose the right tool for the job. Whether it’s a web interface or a cross-platform mobile app you are building, React and React Native are two of the most powerful technologies available today. This blog will answer the question of "what is React and What is React Native" and show how Keploy can help improve test efficiency across both frameworks.

Frontend coding has been transformed by JavaScript frameworks for more than a decade, with developers leaning on the robust tools to create interactive, responsive web applications. The advent of single-page applications and demand for improved user experiences have rendered frameworks indispensable in contemporary web development. In this detailed guide, we’ll delve deeply into the two most used frontend frameworks: Angular and React.

When building apps, it’s tempting to dive right into writing code. But if we do this, there’s a good chance that our code will eventually break, as new changes are made and new features are introduced. This is particularly true of React, a library that’s constantly evolving. Testing in React isn’t only about catching hidden bugs but also about maintaining code quality day-to-day.

Whether you can’t decide which React component library to use for your React applications, or you're simply curious to know how the popular libraries stack up against each other, you're in the right spot. In this article, I will compare ten of the most popular React component libraries and evaluate them based on popularity, robustness, and other qualities. The best component libraries have support for other elements of React (like React hooks) and a broad user base.

Every day, thousands of new apps make their way into the mobile app world. Remember 2018? That’s when app downloads shot up by 9%, and smartphone users spent a jaw-dropping $100 billion on apps. Crazy, right? Now, let’s talk about custom app development and cross-platform apps. By 2018, their market had already crossed $7.5 billion. But why are we going on about 2018?

Today, there are approximately 7 million people who say they wouldn’t be able to survive without their gadgets. Because of this, businesses must modify their websites and applications to cater to their client’s expectations. Emerging patterns prompt businesses to consider creating iOS and Android mobile apps with the top framework libraries that may greatly streamline and accelerate the development process.

We are excited to announce that the Ably Chat SDK for JavaScript now includes support for custom contexts and hooks for React and React Native applications allowing developers working with these platforms to integrate chat features in an efficient and idiomatic way. Ably Chat is designed to meet a wide range of chat use cases, such as livestreams, in-game communication, customer support, or social interactions in SaaS products.
