 All right, welcome back everybody. It's Eric Vitaman here at Chrome Dev Summit 2016 just starting the afternoon sessions I'm here with Drunax PM and all things web platform is my understanding All things is a little bold statement. PM on several things web platform Several very important things and speaking of important you gave a great talk on client side storage and all things that Chrome is doing for that Can you give us a little overview of what you talked about? So the main thing I was trying to say in the talk was that Offline is really important and it's something that we've talked a lot about here at Chrome Dev Summit, but It's really also a very effective way to use caching to improve your loading performance. So client storage is not just Offline it's also a massive performance win. It's kind of the crux of the talk And don't forget about things like browser caching like all these things do still apply even with all these really amazing new APIs You talked a little bit about some cool stuff that I'm really excited about which is promises for index database new file Writer API can you talk a little bit about those? Yeah, so you see a lot of libraries available these days that offer promise wrappers for index DB So it's clearly something people really want Unfortunately, it's kind of complex right like promises don't map directly to transactions very well So we're still hammering out the details, but it's an open area of exploration It's something we're hoping will be coming sooner rather than later. We're working on the spec for that Rightable files on the other hand is something pretty completely new I mean it's something that people have kicked around for a long time. I know It's one of the main reasons people use electron. It's very popular there The idea being that instead of having to upload and download files all the time, which is not a great user experience It's not super Super quick and seamless instead. We want to give sites the ability to have persistent handle to Files on the user's native device, so it's not sandboxed and This allows you to on repeat visits to the site They can just open up that file and immediately read contents out of it You get use cases like having a folder that play music or Spotify web app or something can monitor and upload files from your collection or having a most recently used list for Text editor or photo editor something like that. It's like one of the last endeavors for PWAs is having like a writable file system So one last question before we wrap it up here. I understand your grandmother was watching your presentation Did she have anything to say about it? She did. Yeah, so her exact quotes were I believe Blesses all so that was those great. Hopefully that's a positive blesses all not a Blesses all and then I'm very proud of my grandson. So everyone's good. They laughed at my jokes and yeah, she was proud Okay, with that we'll sign off right now from Chrome dev summit join us on Twitter at Chrome dev summit and on our YouTube channel Thanks a lot guys
