React Native Open Source Update June 2019

Every since Christoph Nakazawa joined the React Native team as Engineering Manager, amazing things have happened. React Native is more "open source friendly" than ever, with the number of PRs from community members doubling, despite the Lean Core initiative. These frequent updates are a great way to stay in touch with what's going on with RN, and a reassuring proof that Facebook is still investing in the technology, more than ever.

Deep Learning in JS

Machine learning is a subject that almost everyone has heard of, but that is understood by few. I'm extremely impressed at how clearly and seemingly effortlessly Ashi Krishnan addressed this monolithic topic, while still packing so much relevant content in only 30 minutes! It made me understand ML much better, I definitely recommend setting aside some time to watch this talk.

Happy Tuesday everyone!

Hope you've had a beautiful weekend! It was very sunny out here, but it's pouring rain today and all week 😭

To make up for the bad weather, I've been playing with the Public Beta of iPadOS, which was released over the weekend. So far, I'm super impressed, and excited for this new era in which tablets play a much bigger role in professional environments. One of the first things I looked up after hearing of iPadOS is whether I would be able to write code on my iPad, and the answer was yes (but not straightforwardly yet).

There was a minor community crisis last week, as Google released a new version of Google Play and Firebase, leading many React Native builds to fail, due to third party libraries having dependencies on these services. If you've struggled (or are struggling) with this issue, the RN core team addressed it here.

Chain React is approaching, with many Facebook Engineers attending and speaking, on top of many other amazing speakers, we're guaranteed tons of quality talks and content! If you haven't grabbed your ticket yet, it's now or never!

Cheers and enjoy your week!

State of React Native

Deep dive: How do React hooks really work?

I know, I know, Hooks are old news by now, and everyone's tired of seeing article after article being published about what you can do with them. This one's different, though. A common criticism I've heard in regards to Hooks is that they are "magical", people don't understand how they work, and they are scared to use what they don't understand. In this great write up, Shawn Wang (aka swyx) rebuilds hooks from scratch, in just 29 lines of code, demystifying the "magic" behind them.

Upgrading React Native to version 0.59 and beyond: a step-by-step guide

React Native 0.59 came with a lot of goodies, such as Hooks and support for JSC, but it also came with a newly cleaned up repo, meaning upgrading is not a piece of cake, especially if you're coming from an older version of RN. The author of this article goes through a step-by-step explanation of how to go through a relatively painless upgrade. Check it out if you're planning on upgrading soon!
