In this course we will explore react-native as a framework for building macOS applications. Unlike web based tools, react-native offers a lot of benefits when it comes to performance and the ability to leverage native functionality.

React-native is not without its difficulties and the jump to a desktop environment requires not only novel technical solutions but also a different way of dealing with APIs and UI patterns.

In 30 lessons we cover setting up a scalable application architecture, connecting with native macOS APIs and exploring some workarounds. The course comes with a lot of new techniques, code samples and detailed instructions to develop React Native apps that are truly equal to native alternatives.

Taught by Oscar Franco, who has worked in several companies as team lead and CTO, released a bunch of React Native apps and has contributed many of the newest latest techniques for react-native-macos.

In this course we will learn how to create modern macOS applications using react-native, take advantage of all the goodies react-native provides on the mac.

Before moving on to the final part of the module, we need to discuss some other limitations of React-Native-macOS.  Whilst some of these are not show-stoppers it is worth mentioning before you dive headfirst into building your app.

Hermes is a JavaScript engine created by Facebook to cut loading times on Android. It does so by storing your JavaScript code as bytecode - this helps by not having to parse it in-device as it can be directly loaded, particularly useful on lower-end android devices and indeed on all platforms where you can ship bundled JavaScript. It should be released soon for iOS (with React Native 0.64), but it is available right now for macOS.

Enabling it is super simple; follow the instructions on the Podfile and uncomment the following line:

# macos/Podfile

# To use Hermes, install the `hermes-engine-darwin` npm package, e.g.:
#   $ yarn add 'hermes-engine-darwin@~0.5.3'
#
# Then enable this option:
#   :hermes_enabled => true

 (even though right now they are a bit outdated).

A word of caution! This is very new technology and in my experience there are subtle bugs. I had an issue where it completely froze my app when handling a large number of promises, meaning I had to revert to jscore (the default engine on apple devices). However if you have a very large JavaScript bundle it might help you cut your app's launch time.

Remember always to check the [official docs](https://microsoft.github.io/react-native-windows/docs/hermes) (even though right now they are a bit outdated).
