The Elm Architecture is the wrong abstraction for the web

The Elm Architecture is the wrong abstraction for the web

In this article, I'd like to explain why I think The Elm Architecture is fine for small components, but quite harmful for websites based on pages.

Definition and Pros/Cons

First, let's clarify what I mean by "The Elm Architecture".

The Elm Architecture's webpage describes it pretty well.

JQL Syntax for the Impatient

JQL Syntax for the Impatient

There are a few JQL syntax bits to get you started:

  • AND --- allows you to add qualifiers to a list
  • != Thing --- target one thing
  • is in (List, Of, Things) --- target a bunch of things (Done, Closed, Resolved) typically
  • not in (List, of, Things) --- do not include a bunch of things
  • -1w --- relative time. You can also use -1d for day
  • "2015/3/15" --- specific dates

Meteor Full Stack How To Learn

#How do I become a web app developer - Meteor style

What does an aspiring web developer need to know to develop a Meteor app? Below is a list of languages, frameworks, libraries, packages & more ;) .

The lists that follow are purposely ordered, unless noted. This article does not explain why you need to learn each item (that is up to you to figure out). Instead this article's purpose is to provide a quick roadmap or "thousand mile" view of the technologies a Meteor Dev works with daily.

When you are in the weeds of learning new things it feels good knowing you have a map to reference and measure your progress against.
