 Hey everybody, it's Eric Bidelman here at Chrome Dev Summit day two. We're just getting things underway for the afternoon I'm here with Malcolm a product manager from Lyft team I think you actually kicked off the day this morning talked a little bit about how you guys built Just an amazing progressive web app really lightning fast Can you kind of highlight what you guys did and why you decided to build up a PWA? Yeah, sure We built our PWA actually came out of a hackathon project You know similar to how Lyfts came out of a hackathon project for our original company and product Zimride our ride.lyft project came out of a hackathon project and The reasons why we built it, you know number one We wanted to prove that a it was even possible to build a web app and possible because as Lyft is a native Mobile first company. There's a lot of skepticism as you know Can it really match the performance and usability and user experience of our iOS and Android apps? But more or so the main use cases were number one greater reach So we want to be able to support unsupported age-out devices As we for example, you know eventually deprecate older OSes number two essentially reduced friction So pushing users through an app store is very very inefficient Right so being able to optimize on that and then finally, you know a little bit more on faster deploys and experimentation So certainly deploying code fixes Experiments a be testing on web takes hours not weeks So we asked a little bit about that because you know I've built a few PWs myself Certainly probably not as large as Lyft or you know an application like that But like are you guys iterating quicker? Like how do you get the performance? Like there's some really cool things you guys are doing in the app. Yeah, definitely I mean, I think our team worked on the alpha roughly two months It took us, you know, just a couple engineers and we slowly built that team up And we rebuilt the entire stack on react to a beta version and that was only took about one month really So productivity was very very quick, you know, we were able to do it a lot faster In fact four times faster than our native usually moves And so from a performance standpoint from a productivity standpoint timeline perspective, it was definitely, you know smooth That's so awesome. So one last thing. Where can people actually try this out? Yeah, just go to ride.lift.com and check it out. We'd love your feedback It's very much a very early preview of the beta, but you know, there will be bugs So just reach out to us if you find those bugs, but yeah, check it out. That's awesome I'm super excited about that. So check that out. We're here at CDS all day today So check out our stuff on YouTube. Hashtag Chrome Dev Summit. We'll see you guys later
