Why handle errors in React? It helps avoid the white screen of death and lets users recover from errors. Let's look at two main ways to do it.

Handling errors in your React projects is vital for a great user experience. Explore try-catch and React Error . #React.

I recommend using react-error-boundary npm package. It not just displays the Error Boundary but also allows you to recover.

🌟 Method #2: React Error Boundary. Introduced in React 16, error boundaries catch errors in child components and display a fallback UI. One can be used throughout your app!.

Why?. It spells out each step, unlike declarative code. You need to check for errors for each component that might throw an error.

🛠 Method 1: Using try-catch. Straightforward to implement but it's imperative and needs explicit checks for each component. But it is recommended for top-level use.

Need to call a child method from a parent in #React? . Use the 'key' prop! Increase the key in the parent to trigger a method in the child with useEffect. Check out the screenshot for the code example. A handy way to refresh child components! 🎉

🚨 Why you should avoid using the 'disabled' attribute in web development? Opt for 'aria-disabled' instead!. Using 'disabled' can cause navigation issues for keyboard users. 'aria-disabled' offers better accessibility and helps screen readers understand the control state.

🛠️ Found a really cool trick to check if a function is slowing down your React component! . Use console.time('label') to start a timer and console.timeEnd('label') to stop it.

6️⃣ Caching: React 18’s cache function remembers results, reusing values without re-execution. 🗃️.#React18 #AppPerformance #WebDevelopment.

4️⃣ Suspense: More power for data fetching! Render fallback components while data is being fetched. 🎢.

3️⃣ Server components: React now sends serialized components instead of HTML. More performance in reconstructing the component tree. Note: limitations on hooks and window. 🖥️.

2️⃣ Transitions: Mark updates as non-urgent with startTransition. The total blocking time sees a significant improvement. 🚀.

1️⃣ Concurrent React: Pause, resume, or even abandon rendering to avoid UI blocks during rendering. Meaning, React can pause rendering of component to handle important UI interaction like click. ⏸️▶️.

🎉 React 18 is a game-changer for app performance. Let's explore how:.(Thread).

Start with a Figma file. Get the basic prototype of your app ready. Don't fill any colors. Just use grays. Don't worry about adding icons. In short, make important layout decisions in the design stage. Leave the minute details for later on.

Now don't take it otherwise and start designing every feature. If you're a designer, you can do it. But for developers, I wouldn't recommend doing so.

But why start with a design first?. I don't know about you but when I start a new app, I hate staring at the blank screen. Not just that, by starting with a design you know the end state of your product and it motivates you to keep going.

I am building an app that lets you log your activities and helps you keep track of your time. Here's how to start designing your app. #buildinginpublic.
