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

Note for community:

A. IdentityServer3 docs, samples and source code use OIDC & OAuth2 terms interchangeably to refer to same thing in many areas. I think that's make sense because OIDC introduced as complement & extension for OAuth2.

B. IdentityServer3, STS, OP, OIDC server, OAuth2 server, CSP, IDP and others: means same thing (software that provide/issue tokens to clients) as explained in [Terminology] (http://identityserver.github.io/Documentation/docs/overview/terminology.html).

C. Grants and flows mean same thing, grant was the common term in OAuth2 specs and flow is the common term in OIDC specs.

D. This document will not focus on custom flow/grant.

E. [Important] Choosing wrong flow leads to security threat.

// General hints on defining types with constraints or invariants
// 
// Just as in C#, use a private constructor 
// and expose "factory" methods that enforce the constraints
//
// In F#, only classes can have private constructors with public members. 
//
// If you want to use the record and DU types, the whole type becomes
// private, which means that you also need to provide:
// * a constructor function ("create").
