Firebase Environments

Last updated: October 21st, 2019.

At the time of writing this gist (January 4th, 2017), I was unable to find true sandboxing to separate development and production environments for a Firebase project. The closest we can get is to create two separate Firebase projects -- one for development and one for production.

Pros

Complete separation and isolation of all Firebase features.
Freedom to experiment without risking the corruption of production data.

Cons

‪“‬In what way is JS any more maintainable than CSS? How does writing CSS in JS make it any more maintainable?”

‪Happy to chat about this. There’s an obvious disclaimer that there’s a cost to css-in-js solutions, but that cost is paid specifically for the benefits it brings; as such it’s useful for some usecases, and not meant as a replacement for all workflows. ‬

‪(These conversations always get heated on twitter, so please believe that I’m here to converse, not to convince. In return, I promise to listen to you too and change my opinions; I’ve had mad respect for you for years and would consider your feedback a gift. Also, some of the stuff I’m writing might seem obvious to you; I’m not trying to tell you if all people of some of the details, but it might be useful to someone else who bumps into this who doesn’t have context)‬

So the big deal about css-in-js (cij) is selectors.

	let values: Observable<Int?> = [1, 2, .None, 3, .None, 4, 5].toObservable()


	// Method 1: using a free function
	// Requires passing the function to `flatMap`

	func ignoreNil<A>(x: A?) -> Observable<A> {
	return x.map { Observable.just($0) } ?? Observable.empty()

	# TEMPORARILY disabling (e.g. STOPPING via 'bootout') unwanted services on macOS 11 Big Sur and macOS 12 Monterey:
	# This version is for a special boot that optimizes for real-time music performance and streaming video.
	# Due to the read-only system volume introduced with macOS Catalina, this script can NOT be run in Recovery mode's Terminal.
	# For my purposes I leave WiFi enabled, for streaming video to a local router with no internet connection.
