E-017 - Doctorate in Voodoo Science with a concentration in F.O. (Flatlist Optimization) Sep 10, 2020

Show notes

Spencer and Jon help you boost the performance in your Flatlist components, because if implemented badly, it can really take a toll on your app, rendering blanks, and causing laggy behavior.

They dig into various performance boosting items you can take a look at in your own app. Walk away with faster loading lists, control scrolling and the memory associated with your items.

E-016 Hope Springs Eternal Disappointment (Animations with React Native) Sep 03, 2020

Show notes

This week Jon drives down that Road To Hell he paved with good intentions, and faces the fact that hope sucks and he'll never have time to do the things he wants to.

On the brighter side of the podcast, Spencer dives into various ways to make things move in your app, from screen transitions, interfacing with gestures to moving pictures around on the screen. This primer of the various popular animation libraries will help you get started, or at least familiarize yourself with the differences if/when you hear or read about them.

E-014 FireBase Aug 20, 2020

Show notes

These days it's super easy to build an app with robust back-end APIs. No one has time (or let's be real, desire) to do dev-ops, so we talk about FireBase and it's myriad of offerings from simple key/value store through various extensions like image resizing.

We have some weird phone news as Microsoft is back in the phone game again, Air BnB tries to go public even with a big COVID hit to their business (and Apple breathing down their neck) and we get our first iTunes ratings and review! WOOT!
