Elm

Elm is a programming language that compiles to JavaScript. The highlight features are great performance and no runtime exceptions. You can read more about all that on the home page. Elm also has its own virtual DOM implementation that is very fast compared to React, Angular, and Ember.

This repo focuses The Elm Architecture, an architecture pattern you see in all Elm programs. It has influenced projects like Redux that borrow core concepts but add many JS-focused ideas.

The Elm Architecture

The Elm Architecture is a simple pattern for architecting webapps. The core idea is that your code is built around a Model of your application state, a way to update your model, and a way to view your model.

To learn more about this, read the the official Elm guide and check out this section which is all about The Elm Architecture. This repo is a collection of all the examples in that section, so you can follow along and compile things on your computer as you read through.

Run The Examples

After you install Elm, run the following commands in your terminal to download this repo and start a server that compiles Elm for you:

git clone https://github.com/evancz/elm-architecture-tutorial.git
cd elm-architecture-tutorial
elm-reactor

Now go to http://localhost:8000/ and start looking at the examples/ directory. When you edit an Elm file, just refresh the corresponding page in your browser and it will recompile!
