React Lifecycle Visualizer An npm package (react-lifecycle-visualizer) for tracing & visualizing lifecycle methods of React class components. (For function components and hooks, check out react-hook-tracer instead.) To trace a component, apply the higher-order component traceLifecycle to it, and ...
The above is the life of a React component, from birth (pre-mounting) and death (unmounting). The beauty of React is the splitting of complicated UI’s into little, bite-sized bits. Not only can we thus compartmentalize our app, we can also customize each compartment. Through lifecycle m...

You can’t guarantee the AJAX request won’t resolve before the component mounts. If it did, that would mean that you’d be trying to setState on an unmounted component, which not only won’t work, but React will yell at you for. Doing AJAX in componentDidMount will guarantee that the...
Lifecycle Phases and Methods of React Class-based Components and their Equivalent Hooks in Functional Components
Lifecycle Methods in Functional Components Ionic React exports hooks for each of the lifecycle methods that you can use in your functional components. Each of the hooks takes the method you want called when the event fires. import{

Async data fetching requires extra-effort to fit into the declarative nature of React. Step by step React improves to minimize this extra-effort. Lifecycle methods, hooks, and suspense are approaches to fetch data in React. I'll describe them in examples and demos, distill the benefits and dr...
Effectively managing React lifecycle methods ensures your components perform reliably and efficiently. Misuse can lead to memory leaks, redundant renders, or degraded performance. Below, explore key tips to prevent common pitfalls and make the most of the React component lifecycle. ...
So React component lifecycle can be divided into three phases according to these statuses: mounting, updating and unmounting. 2 Mounting React.js exposed interfaces or hook methods in each phase of component lifecycle. 2.1 Initializing state
