Summary

Scott and Wes dive into Remix 3, exploring how it embraces native web standards like Events, Signals, and Streams to become a truly full-stack framework. They unpack what “LLM-ready,” thin APIs, and a standards-based approach mean for the future of web development.

0:00.0	Welcome to Syntax. Today we're talking about remix three. I went to Remix Jam, which was their
0:07.6	conference in Toronto on Friday. And they gave us a CD, which is wild, with a demo on it.
0:16.1	And it was a fantastic conference. And basically what they did is they showed us what remix 3 is going to be.
0:25.4	So it's no more React.
0:27.2	It's this brand new thing that they've thought up.
0:29.1	It's full stack.
0:29.9	We're going to try to explain all of the little bits of it today here.
0:34.8	We're not going to go super in depth.
0:36.8	Like Ryan and Michael had, I don't know,
0:39.5	probably like four hours on stage and they still didn't get to the entire framework. So I'm
0:46.4	not going to get into every little, little bit of it. But I do hope to sort of explain to you the
0:52.0	angle and the ideas behind it. And then we're going to have Ryan and
0:55.2	Michael on in a coming episode to talk a little bit more about like, why did they do things?
1:00.9	And what are the, what's the component model look like? And why, X, Y, Z. You know, all the,
1:06.1	all the nitty gritty. So just as like a background, remix was a full stack React framework. And a lot of
1:15.7	those features or almost all of those features have moved back into React router. And remix, as you
1:21.9	know, it is essentially gone. And it's been reincarnated as a new full-stack framework that has has nothing to do with React
1:31.3	other than a lot of the ideas that they have are because they are fed up and frustrated with
1:40.1	the state of the React ecosystem. And that a lot has changed since React has sort of been rolled out.
1:49.0	So they kind of like peeled the back and said like what would a simple,
1:54.3	dead nut simple JavaScript full stack framework look like if we were to design it from scratch today.
2:03.1	And I'm pretty excited about it.
