[00:00:00] swyx: I'm continuing my exploration of how technologies get adopted. And recently there was a really good interview of Christopher shadow by Beyang Liu on the source graph podcast. So I really had to feature it. this tells the story of the invention and adoption of react native internally within Facebook. And the context to this is. 

[00:00:21] Facebook had a problem with the iteration speed of mobile apps at Facebook, and they were much slower than web apps. So basically the context before this conversation is that mark Zuckerberg had actually set an engineering priority to fix the solution and the engineers have to figure it out. 

[00:00:36] Christopher Chedeau: One of those things that John had in mind, Can we embed JavaScript in a iOS app. And so at that point, we actually there was no API for this and they're going to do it, but like you found a way to cross compare something and he was able to do it. And you, you want it to be like, okay, can we run, react and power, like native iOS views out of react instead of like dibs and spans, you can like a UI label and a UI views. 

[00:01:03] And. And so this is like at Facebook there's hackathons. And so in the summer does a three day hackathon. And we basically like Ashwin Lynn that's where on my team, on the photos team. And Joanne, we hacked together off for three days working on this like raw using react to power, like native use. 

[00:01:25] And at the end of the three days, we had a demo where we are able to show his view and we had a primitive layout system. And. I have the texts it's on the right and the iOS, the rep on the left and basically moved the line like a before and after and a native, iOS, like button. And I bought to move the, like better from the left to the right. 

[00:01:49] And we were able to click on it. Now, the lights like actually like walks and we're able to like, do. Changing and saving would be like almost entirely. I think it was a hundred milliseconds, a refresh. So it was barely perspective perceptible and we presented to the like hackathon group, like all the, did some callbacks could go. 

[00:02:11] And what happened is the five project, like most interesting have an audience with Mark Zuckerberg. And so you went to present this hack to Mark Zuckerberg and there was a SRAP, the CTO of the company as well, like in this? Yes. Yeah. And wasn't for this. Yeah. And both of them were like, we're super excited. 

[00:02:32] And what happened the next week is we basically did like a wall tour of Facebook and we talked to all of the management chain, . And it was like a super, like a fun thing. But now the thing that happened then is okay, so we did this demo, there was like people liking it and everything, but now for like myself as an engineer, like I joined like Facebook, like less than a year ago. 

[00:02:54] And I moved like my, like myself, I married my wife. I like, this was like a huge like thing. We moved off way across the world. So now it was like a soul searching moment. Do I want to like bets, like this dream, like on a crazy idea that and I was like, like at that time I was like the answer was No. 

[00:03:18] And so what happened is like a Lena Nash Ashwin basically went and B up like a, they wanted to do an iOS photo up and they built it using what was react iOS at the time. And three months after they basically came back to us and said Hey look like we really want to build like the iOS photo app. 

[00:03:37] Yeah. And right now we're spending more time building this react iOS thing than actually building the products. And so we're going to restart the product like in a normal iOS. So we can actually walk on it. The project could die. All the project could live and I need to make a call. Do I want to invest in? 

[00:03:58] And so I did a lot of soul searching and I basically at that point I was like, okay, I think I need to do it. And so, Tom Occhino was the manager of a Joel at the time. And Joel Dan and myself okay, now we like basically creating a small team. And then she came in after this. And this is how like the program. 

[00:04:17] But this was like not an easy, like a decision to make. And this is like something, a lot of people don't realize it counting products and like they're super high risk Harry, well, for decks, but most of the projects actually fail. This is a startup. Like most of us, not the film and the fact that I'm like here talking to you, like all of the stars align and everything, like it's good work, but this was not a given at the time. 

[00:04:40] Beyang Liu: You took a risk and it paid off. And I think especially it was a big risk in Facebook at the time. Cause my understanding is that they had already tried to build an initial version of the mobile application using web technologies. That was like the first attempt. 

[00:04:54] And then it wasn't like performant enough for the user experience. Wasn't good. So they ended up rebuilding it in, native iOS and Android. So there must have been like probably some amount of institutional resistance. Right. . Have another go at a web based or web inspired technology, right? 

[00:05:11] Christopher Chedeau: Yeah. Yeah. This was like a very interesting time. And like one of the things that's also I don't know if it's true today, but like when I like joined Facebook and even at school, there was this notion of if you're doing web, you're not a real engineer. If you're doing like a channel or like network or native, like you're real engineer. 

[00:05:31] Yeah. And so there was this like super interesting notion where we are coming from a web background. And so when you have all of these preconceived notions, Whatever we'll doing is not going to be a real engineering. And we're like, scripted is, and let's do this. And this is like very interesting. 

[00:05:52] The other thing which has been super interesting is there's also a very big difference between the iOS community and general. Hmm. And so, the what's super interesting is iOS community is like apple, like plays a central role. And basically there's like this notion that like everything that apple does is the right way, and this is the way things should go. 

[00:06:16] And there's a very angry notion of this. And so now if you're basically come in, like we're doing something different when apple guideline, there's a lot of reasons. Yeah. And so this is in practice it has works well because like apple in practice, the software that they produce and like the libraries and everything, I actually really good in practice. 

[00:06:36] So that's reasonable. But it's been like one of the very interesting thing about trying to convince people the, on the other side for Android, which was super interesting is Android, like the state of the development at the time was like very fragmented. There's 20 different of Android and everything is hiking and like the quality of the framework and the fraud, was not as good. 

[00:06:57] And so basically like 400, ...
