Hey everyone! I just launched 🚀 Project React, which is a course that teaches you React by building a real-world project. It goes way beyond what you see in these videos and walks you through step-by-step on how to build a big and complex application with React! You can check it out here: cosden.solutions/project-react

What you say "This is the last video you are ever going to watch", is actually 100% true. Just amazing explanation 👌🏻

I had to watch few parts of the video twice, but got it at the end. Amazing explanation, you got one more subscriber 👍

Pretty clean explanation. Easy to understand. Thank you

Great explanation. Thanks a lot 👍

Beautiful. I didn't think you could have such a refined control of rendering by using hooks like this.

Sick video. Pretty advanced stuff.

Cool, now I understand useTransition and I won't need to look at other videos and solutions for this. Great explanation.

Thank you so much!!!

Excellent.

Much simplified than the info from the docs :)

Bro that was helpful 😄😊

perfect example

Clean

your a goat

Simple but so juice... hehe

React sends one rerender with currentState and isPending:true to component to tell it will start transition. Then it will rerender component with newState if during this rerender (probably slow) another update is raised, async rerender will be stopped

Quick Question? Can I use the useTransition to put the loading state for side effects functions For e.g. if I have to update the user and I'll wrap the start transition on update function. I can use the isPending state to show that is updating or likewise.

so basically useTransition is just debouncing the function to be invoked a little bit later(in milliseconds)?

u are right i don't need to read or see another thing

Neat. So what happens to components that render direct from manipulations like chart libraries or canvas libraries? They don't work because react has no way to stop them right?

@cosdensolutions

depends, if they are driven by state, this will control when that state gets interrupted or not

does the useTransition hook work with react's userReducer just like it would be useState?

Awesome. Simple and clear explanation. But I have a question regarding POSTS page. How can we resolve the UI freezing issue for Posts page? Or how can we load Posts page content faster? Can you help me with this? Thanks.

only render a few at a time. So either use virtualization, or paginate them and load them 20 at time

Why does my script to animate in page router doesn't work in app router of nextjs

hello, Can you explain this one please - while (performance.now() - startTime console.log("entered while...", performance.now()); // Do nothing for 1 ms per item to emulate extremely slow code } performance.now() - startTime < 1 should always be greater than 1 isn't it? I don't know why is it going inside the while loop and what does 1ms delay is derived. Would be great if you can please explain.

this code just forces the component to wait 1ms before continuing the render. It comes from the React docs in their examples! It just simulates slowness so that you can actually see the effects of what you are doing

why not use loading instead

seems like same with the suspense lazy load what are the difference between them?

@cosdensolutions

suspense is for delaying the loading of something and this is for interrupting it and prioritising other renders first

Many thanks. Is this working also using next/link?

Hello, Loved your explanation but it does not seem to work with this piece of code. const buttonClick = (type: string) => { startTransition(() => { if(type === "fast") { setCounter(25); } else { setCounter(() => { let sum = 0; for(let i =0; i

@cosdensolutions

because startTransition works by interrupting renders that take too long after being set, not the actual setting of a new value. In your case, you're just taking a while to set the new value to trigger a re-render, but the actual re-render is super fast as it will just update the counter with one value
