    Topics and Questions:

     0:45 –  Todays discussion cover PWAs (Progressive Web Application) and where they fall in the category of development for mobile

     0:55 –  Eric is the author of Programming JavaScript Applications and Composing Software. Eric also worked with Adobe and help build Adobe Creative Cloud, previously Eric built video applications for the BBC network, and had created music applications that are currently apart of Youtube’s artist pages.

    1:50 –  Nader ask about what Eric does day to day and What a good definition for PWAs. Eric share what a PWA is and how it fits intro building web apps.

Eric explains how Service Workers are a kind of a caching layer. Eric explains how this caching layer help load the app offline. Eric talks about Size Limits on the Service Worker. Eric goes into how the Service Worker is like hitting the network.

    31:00 –  Nader ask about performance and latency. Nader ask about opinions on technology use for the APIs. Eric suggest the situation as a way to gauge to pick the API tool like GraphQL, Rust, and others. Eric thinks GraphQL is best for an MVP.

    33:00 –  Nader asks about transition when building the PWAs. Eric says this can be express when using Next.js, because it can be done later.
