Ideas and guidelines for architecting larger applications in Elm to be modular and extensible

Architecture in Elm

This document is a collection of concepts and strategies to make large Elm projects modular and extensible.

We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp. You will probably merge a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:

  1. There is a single source of truth. Traditional approaches force you to write a decent amount of custom and error prone code to synchronize state between many different stateful components. (The state of this widget needs to be synced with the application state, which needs to be synced with some other widget, etc.) By placing all of your state in one location, you eliminate an entire class of bugs in which two components get into inconsistent states. We also think yo

Getting a Mocta object

NSUserDefaults<Mocta> *defaults = [Mocta objectWithClass:[NSUserDefaults class]];
id< UITableViewDelegate, MoctaStub> delegate = [Mocta objectWithProtocol:@protocol(UITableViewDelegate)];

Expectations

Expectations are ran on dealloc, or at the end of the test case, so I don't have to do it manually.

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…
