It's actually interesting how React team managed to miss on this, since there are select few libraries that are even able to work with Suspense. The fact that their tests didn't include react-query is pretty funny
From the library side of things, the fact that React does not ship its own typescript types bundled toghether during installation makes things so much harder. It makes it so that the installation/upgrades need to be orchestrated with the "overrides" field in the package.json (to match the types package) is something that makes it much more of a chore (especially making sure you have the right version of the types installed 😮💨). I understand from the outside some may see it as "oh, you guys should know to do this..." or "common! it can't be that hard!". But given that we are already swamped, this extra burden is something that's most of the time just not worth the hassle. Please ship your own typescript types!
Nowadays, I still use the old "{ loaded ? : }" to fully control all the data fetching behaviors. even naivest person in the team can understand what it does. instead of guessing the "". I know it's verbose, but serious question though: is there any speed, performance, render improvement, or edge case where is good for? I only care about performance improvement, hence if the can bring a better UX to the end user. My own DX is less matter in this case.
If you have a slow component shouldn’t you memoize it? Seems like we have a pattern to handle that situation already. Also why not just create a second component. Keep suspense the same and create another version that blocks.
It is not ok for components to trigger a rerender of previous ones. Suspense should not waterwater, otherwise it is useless. They should keep fetching all at once, but find solution to do not rerender components with previously fired promises.
This is a trash change. If your component is slow to render, you almost certainly abstracted that computation away into a use effect or similar hook - so the thing they are optimizing for is something that the developer should have addressed. Making this force a waterfall execution is optimizing for bad behavior and a major code smell
Two of the big issues that caused this seem to be that they failed to understand the use case, and did not note that the change was a breaking change to previous behavior. The response to feedback though is one of the best examples of properly handling things I've seen in awhile.

@@DmitriiBaranov-ib3kf Tbh I haven't used Vue or its meta framework Nuxt yet, but I'm sure you're definitely right I mean... Hell! At this point even JQuery is much more efficient than React lmao
If they want to change the semantics, they should introduce a new name for it and not change the existing primitive. They can deprecate the old name and give people time to adjust or have the old behaviour via a plugin for devs/teams that want/need it. Even though it's a major version bump, changing the behaviour of a freqently used primitive underneith people is an awful move.
I typically use React-query and render the loading / error states in the component. What I don’t understand about Suspense is why would you want to couple loading states for multiple components into one? Ie. if data is ready for one component just render it. Isn’t that a better UX? Why wait for *all* child components to finish fetching before rendering them all at the same time?
You are an extremely intelligent person. Not always right, but scary smart making me realize being lazy and entitled is not an option. You’re more talented and knowledgeable than me in many ways. So Thank you for doing this and helping some of us keep up!
Why not just wrap each component in its own suspense boundary though. The way I tend to think of it is a component that does its own data fetching should probably be its own page. Its okay for a component to do a mutation though since in that case are are re-rendering everything anyway
They want everything to pop out at once i guess, which means every component should be a child under suspense, if not, it will cause the popcorn ui problem which means unpredictable CLS order
Suspense was never announced stable for data fetching. Here is what happens when you jump on a hype train too soon :( "Suspense-enabled data fetching without the use of an opinionated framework is not yet supported. The requirements for implementing a Suspense-enabled data source are unstable and undocumented. An official API for integrating data sources with Suspense will be released in a future version of React."
This is so frustrating :) First you get this shiny promise about suspense being good for rendering async stuff, and then they say that they remove it. What is the point? To create more buzz around the library?
Inability to stay on course and living reactively can be a sign of depression. Depressed libraries concentrate on immediate at hand problems, because their programmers are in a stressful state and they cannot focus on long term goals.
Ah I was at React Summit :D Was excited to see you there but then saw you were remote. I'm sure my company will send me off to the US on in 2025 though, so always next time :)
23:22 "What we should do instead is immediately unwind the stack as soon as something suspends, to unblock to loading state." I agree the stack should be unwound instantly, but not by forcibly unwinding it with the new waterfall mechanism, but rather it should be naturally unwound by programmers taking care to offload any heavy work off the main thread. Can't be hackishly fixing main thread sluggishness by introducing this type of solution. This is just the first thought that has come to mind, willing to be convinced otherwise.
Maybe I'm not web-brained enough for this but both of these seem unreasonably inefficient. Why doesn't first fetch the data for each element inside, asynchronously, without progress in one element re-rendering the others, and then when all are ready, renders the whole hierarchy in one step? That way you don't get the insane constant re-rendering of the React 18 implementation, and don't get the slowness of the React 19 implementation.
can't they just put every child of a suspense(Or every other parent component for that matter) in a promise wrapper so that they're forced to run fetching/rendering in parallel and wait for a Promise.all(Settled)?
Solid JS is the future I have to say I moved to it almost 2 months ago and so far I love it I ported one of my major projects (built with NextJS) to it in 3 weeks and man the performance is now light years ahead from what was made with React!
learning about react makes me very happy I'm not working in this world of CS. like it's all very odd abstractions and i often don't understand why they make such odd decisions
Really good video. I don't really know much about React but still accessible and interesting. It reminds me of the back and forth that was happening in Laravel over lazy loading models through their relations with other models, which from a performance viewpoint is awful, but it's really convenient. It has the same trade-off between trying to foresee in advance which data you'll need and should preload. This might be a case of the "No Free Lunch" theorem ( en.wikipedia.org/wiki/No_free_lunch_theorem ), where it's not possible to have one implementation that's the best for all use cases.
So boundary actually triggers when a promise is thrown, which terminates the rendering because of the exception, and that forces to re-render each component again untill all of them under the same are done so it no longer has to throw and just render their contents with the resolved promises?
Maybe I'm naive, but couldn't Suspense just render everything inside hidden elements (or some equivalent in the virtual DOM) and then unhide them as they become available? Then it wouldn't need to discard any renders and you'd get optimal performance.
Each day we stray further from simplicity. I remember when I picked up React because I wanted dynamic content, I now realise after observing other frameworks that React is probably the most verbose framework out there to solve this task, and now they're adding more behaviour that gives you more mental overhead when considering project design. This could be a skill issue on my part, and I've loved the concept of keeping everything in one file, but ever since server components I feel like the complexity of these files only seem to grow as more things are introduced, leading to more things to consider. Is it getting out of hand yet? Has it always been so out of hand? Seeing this now, I feel so out of touch. Time to look for simpler solutions.
That’s why react won, the people behind it and around it are just superb and they have made a fantastic community. Thanks for the video, having watched your streams I can imagine how long this took to film and edit!
I don't get why it can't be parallel and without re-rendering. And if re-rendering is a must, at least do it once after the last thing loaded, not after each of them loads.
I'm not a web developer, I don't understand why would you need to render anything at all until all the components in the suspense boundary got their data back? This parallel to sequential change just seem like the wrong "solution" to the problem. Isn't not rendering the components until everything is ready the whole purpose of this suspense?! So Why is it rendered/rum multiple times? With multiple rendering passes you turned on O(N) problem to O(N^2)... that doesn't seem wise to me...
why isn't there just some "prerender" hook on components that can be used for the prerendering instead of actually rendering the whole component and throwing it away xD
@@dahahaka it’s reference to the movie 300 where the Spartans take pride and glory over what’s a decent proposal to make things work and solve an issue. Basically the react way of doing things is self contained functions with minimal external and internal bindings and the React team will die on this hill even after the rest of the world has discovered better solutions. This is Reaaccctttt!
Two solutions seem reasonable to me 1. Avoid using multiple children inside suspense 2. Change react to not rerender child inside suspense if that already resolved successfully.
React and not rerender in the same sentence? You must be thinking of another framework that probably already supports signals, which completely eliminates all this nonsense patches on top of patches just to fix messed up state management
I know nothing about React but I always thought that data only flow top down, so what is a reason to refetch and even rerender all components in suspense?
I mean the whole way suspense works is why I've never liked it. Throwing to signify is still async fetching just is not what a throw is for (correct me if I'm wing about this). I know they need to use javascript primitives under the hood so I see why just never liked or used this way only for code splitting
This is an inevitable situation when you ignore the native capabilities of the web platform and hand it all over to abstractions you don’t own. The Promise API and some very simple patterns makes all this hand-wringing go away. We need to stop injecting so much magic into our projects and go back to good engineering principles.
While it's an interesting topic, I could watch only first half as I realized I was getting sleepy with the same point rephrased 25 times. Maybe because it's from the stream and not a written youtube vid effect but oh well.

Even tho its GQL, but the data colocation, not needing to worry about updating stuff when removing data deps a tree needs or removing components. Lots of really cool stuff that could be fun for the community to get exposure to
This is react, rerendering stuff is the only reason this whole library works in a first place… The whole thing is basically just a jQuery $(selector).load(url) with different syntax…
@@Cmacu Rerendering stuff when it needs to be rerendered. Why does a sibling cause a rerender of a component? Data goes down, events go up, and suspense goes sideways?
@@MarcelRobitaille think about it… how do you remove/replace the fallback from the DOM and how do you know when to do it?… Hint: It’s what happens when you can’t handle state management properly… Sooner or later you might realize that the problem with react is react itself, re-rendering stuff is just the one of symptoms, it’s like a headache… and all this suspense and hook stuff is taking painkillers ignoring the core issue…
@@Cmacu I still don't see why suspense can't render the fallback until all of the children "resolve", cache the result of each child when it resolves, and render the cached results when they all resolve. I see the argument for why just rerendering and not dealing with caching is cleaner, but I think this solution is better than serializing everything like they are doing and it's less hacky than some of the patches of builtins they've been doing.
@@MarcelRobitaille ok. Let me try with clarifying question. So let’s say you load the first suspended element and the others are not ready. The DOM still contains the fallback… Where does the state from the first element go? If react had a cache like you are describing why would re-rendering ever be a thing (regardless of suspense)?
@@m12652 I donno it gave a decent answer. This is the summary: Key Differences 1. Syntax and Usage: • React: Uses a component-based approach where Suspense is a wrapper component. • Svelte: Uses a template-based approach with the await block embedded directly in the markup. 2. Scope and Flexibility: • React: Suspense can be more flexible with nested fallbacks and works well with React’s ecosystem and Concurrent Mode. • Svelte: The await block is straightforward and easy to use directly within the template for quick asynchronous handling. 3. Error Handling: • React: Error boundaries are used in conjunction with Suspense to handle errors. • Svelte: The await block has a built-in :catch clause for error handling. 4. Dependencies: • React: Often relies on additional libraries or utilities to handle data fetching in a way that integrates with Suspense. • Svelte: Provides a built-in way to handle asynchronous operations without additional dependencies.
Some people are like - oh my god! Let's cancel react. It's useless. React 19 is in beta to get to know issues like these right? Am I missing something? And as shown in thumbnail, react apologized on x I guess.

2. Change react to not rerender child inside suspense if that already resolved successfully.
React and not rerender in the same sentence? You must be thinking of another framework that probably already supports signals, which completely eliminates all this nonsense patches on top of patches just to fix messed up state management
I know nothing about React but I always thought that data only flow top down, so what is a reason to refetch and even rerender all components in suspense?

Can you please cover golang trying to remove the ability to use linkname and providing zero alternative for developers?
Please Talk about suspense and suspending and the hooks surrounding it.
And this is why I only use vanilla html and js
I mean the whole way suspense works is why I've never liked it. Throwing to signify is still async fetching just is not what a throw is for (correct me if I'm wing about this). I know they need to use javascript primitives under the hood so I see why just never liked or used this way only for code splitting
What about a single promise not resolving. Then nothing renders.
Me laughing at this while writing my plain web components that will work unmodified for the next 15 years.
This is an inevitable situation when you ignore the native capabilities of the web platform and hand it all over to abstractions you don’t own. The Promise API and some very simple patterns makes all this hand-wringing go away. We need to stop injecting so much magic into our projects and go back to good engineering principles.
Soooo, compiler could not improve performence in this case and still keep it parallel?
While it's an interesting topic, I could watch only first half as I realized I was getting sleepy with the same point rephrased 25 times. Maybe because it's from the stream and not a written youtube vid effect but oh well.
It's called "milking content" when you have nothing better to talk about.

Theo, NextJs, TS ruined React. This guy is stressful to watch. Did everything unsubbed, not interested, don't recommend channel, and still popping up on my feed! Why youtube!?
TS didn't ruin it. NextJS yes a thousand times *yes*

Frontend hell -- the d***thing get overtly complicated for no good reason. No wonder people get sick, tired and frustrated doing Frontend.
I switched to native Android development with Kotlin just weeks ago and I'm in love with the language and mobile development in general especially that Kotlin has only jetpack compose framework for Android.
These frameworks ruined the web and I couldn't keep up.
I'm glad im on svelte kit now
Would you be open to doing a dive into relay?
Even tho its GQL, but the data colocation, not needing to worry about updating stuff when removing data deps a tree needs or removing components. Lots of really cool stuff that could be fun for the community to get exposure to
Why is every component in a suspense rerendered every time, and not only the one wich received data?
What if i just don't want to use react query ?
I still don't understand why the old way had to rerender the siblings. Why couldn't suspense just be basically like promise.all?
This is react, rerendering stuff is the only reason this whole library works in a first place… The whole thing is basically just a jQuery $(selector).load(url) with different syntax…
@@Cmacu Rerendering stuff when it needs to be rerendered. Why does a sibling cause a rerender of a component? Data goes down, events go up, and suspense goes sideways?
@@MarcelRobitaille think about it… how do you remove/replace the fallback from the DOM and how do you know when to do it?… Hint: It’s what happens when you can’t handle state management properly… Sooner or later you might realize that the problem with react is react itself, re-rendering stuff is just the one of symptoms, it’s like a headache… and all this suspense and hook stuff is taking painkillers ignoring the core issue…
@@Cmacu I still don't see why suspense can't render the fallback until all of the children "resolve", cache the result of each child when it resolves, and render the cached results when they all resolve. I see the argument for why just rerendering and not dealing with caching is cleaner, but I think this solution is better than serializing everything like they are doing and it's less hacky than some of the patches of builtins they've been doing.
@@MarcelRobitaille ok. Let me try with clarifying question. So let’s say you load the first suspended element and the others are not ready. The DOM still contains the fallback… Where does the state from the first element go? If react had a cache like you are describing why would re-rendering ever be a thing (regardless of suspense)?
Haven’t done react in awhile, is suspense just like svelte’s await blocks?
But do sveltes await blocks behave the same way? I'd be surprised if they do.
great question for chatgippidy
@@m12652I’m not sure if they can resolve multiple promises, I’ve always created a function to resolve multiple and await the one function.
@@gageracer that clowns a waste of electricity when it comes to anything that wasn't old in 2021
@@m12652 I donno it gave a decent answer. This is the summary:
Key Differences
1. Syntax and Usage:
• React: Uses a component-based approach where Suspense is a wrapper component.
• Svelte: Uses a template-based approach with the await block embedded directly in the markup.
2. Scope and Flexibility:
• React: Suspense can be more flexible with nested fallbacks and works well with React’s ecosystem and Concurrent Mode.
• Svelte: The await block is straightforward and easy to use directly within the template for quick asynchronous handling.
3. Error Handling:
• React: Error boundaries are used in conjunction with Suspense to handle errors.
• Svelte: The await block has a built-in :catch clause for error handling.
4. Dependencies:
• React: Often relies on additional libraries or utilities to handle data fetching in a way that integrates with Suspense.
• Svelte: Provides a built-in way to handle asynchronous operations without additional dependencies.
React in my eyes is no longer the prime example of innovative design that saved the web.
My head hurts. This is seriously making me consider Alpine JS 😅
Is the solution to not use Suspense?
At this point, i dont even know what we're solving.

Some people are like - oh my god! Let's cancel react. It's useless. React 19 is in beta to get to know issues like these right? Am I missing something? And as shown in thumbnail, react apologized on x I guess.
