React Native + macOS + Clojurescript

Project Catalyst

Since the recent release of Catalina, macOS has shipped with the ability to allow iOS/iPAD apps to run on macOS without any modification via a featureset known as Project Catalyst.

This is exciting, as writing React Native + Clojurescript apps as a target for the desktop is much more compelling than a pure Electron app (imo).

Realtime Database triggers with Cloud Functions for Firebase - source

This gist contains the source code in my video series about Realtime Database triggers. You can watch the three parts here:

1. Part 1 (intro, onCreate)
2. Part 2 (onUpdate, infinite loops)
3. Part 3 (onDelete, transactions)

index.ts contains the Cloud Functions code, and dialog.ts contains the script to run

To maximise our usage of the type system, we should assign different types to our objects depending
on the desired purpose.

In this blog post I will clarify two common purposes for objects known as records and dictionaries
(aka maps), and how they can both be used with regards to the type system.
