Future of React - Tom Occhino, Kent C Dodds, Mark Erikson, Theo Browne, etc. - React Summit US 2024

[Applause] [Music] he [Music] [Music] hi everyone we're going to be doing a

future of react panel discussions they're going to be some sweet questions and some spicy questions so let's start off with this uh sweet question which is please introduce yourself I'll start off hi everyone my name is shti kapor I am a software engineer at slack I use react all the time and I'm super excited for this panel discussion because we're going to be talking about react 19 what's coming up what we hate and things about react that we wish we could change I will pass it on the mic to you I'm Eli white I'm one of the software Engineers on the react team at meta hi I'm M I'm

another software engineer on the react team at meta I am Kent C dods and I teach people how to make quality web applications hi I'm Theo and I teach people how to make terrible web applications I'm Mark my day job is a time travel debugger replay and my second unpaid job is maintaining Redux I'm Tom uh I helped create react and now I'm the chief product officer at for sell cool what a cool love you

all all right let's start off with the spicy question react 19 is in RC stage we're so excited to hear when is it going to be in stable stage you're looking at me I'm looking at you you can do it re 19's been really cool because we've really taken a lot of the feedback that we've gotten from people um especially around these suspense changes if you've seen that that um I really want to do a shout out

to Andrew from versel who's like worked very tirelessly to make sure that that that um bug gets fixed and we we address the needs of the community make sure react 19 is good for people um that has been incredibly complicated of a change to make and uh as we've as we've rolled it out I think this week uh people have started sharing feedback they're like oh this is actually what it should have been all along like this is incredible uh there's a couple more bugs that we're we're working through and then we hope

to get it to be stable I have a quick point on this I regularly I'm surprised how many people feel like react is breaking all the time because the delays with react 19 are a beautiful example of the opposite they had an RC it was gold it was ready to go a very very very small subset of apps that used client s suspense in a very very very specific way had performance regressions and rather than ship it and tell them to deal with it they have now taken a long time to make sure nobody's code breaks

or even performs worse than it used to as a result of the changes and I personally think we should take a second to applaud the team for continuing to keep our apps working 10 plus years into these code [Applause] bases love that I love that shout out um actually you mentioned there are some challenges that you're dealing with I would actually love to know what has been sort of the most common bug that people have raised about react 19 that's a good question mu do you have

any ideas here um we've been hearing a lot of compiler questions uh I don't know I think the compilers optin only we're in beta right now we're hoping to get a stable release out um so hopefully we love more feedback on the compiler if that's breaking anything for you nice that's actually a nice segue to my next question which is going to be tell us a little bit about react compiler and what would you like people to know as somebody who's been maintaining react compiler for the last two years yeah uh we're super excited to release it we um
