Learn Elm, Flux-architecture and Pm2

`elm-ui` is a language for layout and interface design. This is a novel iteration on declarative styling where you can use Elm types and functions to define your UI in a declarative way.

The novel part is that it does not require you to know CSS to be used. The API is very simple and can be learned quickly!

The approach taken by `elm-ui` is based on two big ideas: 
Getting the compiler to verify as much of the layout and styling as possible by defining them in Elm code
Enabling refactoring capabilities of Elm for UI code


Elm is a programming language that provides a clean functional syntax for writing HTML web applications. It promises zero runtime exceptions, fast rendering, time-travel debugging, and much more.

Declarative UIs without CSS with elm-ui

Elm is a beginner friendly functional reactive programming language for building web applications. It contains a small but powerful set of language constructs, such as, static types, algebraic data types, immutability, and pure functions. Elm provides and requires the use of a specific architecture that’s well suited for sensible application construction. Elm’s type system and architecture may feel constraining at first, but they ultimately provide the programmer with some neat benefits including comprehensible code, and a much improved refactoring experience.

In this course you will learn the basic fundamentals of Elm so that you can start building applications today.

Start Using Elm to Build Web Applications

As a React application grows, so does the needs for organization and patterns. How do components communicate? How do we manage state across the application? How is data shared between components? 

These are the questions that Flux was built to answer.

In this series, we will explore React Flux, using ES6 (ES2015), babel, and webpack to manage our developer workflow.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

React: Flux Architecture (ES6)

In this lesson we'll look at an overview of how Flux works, setup our application structure and tools, and create our first component.

Flux Architecture: Overview and Project Setup

Functions are an important building block in Elm. In this lesson we will review stateless functions, function composition, anonymous functions, Currying, and more.

Functions in Elm

Getting Elm installed. We will install the Elm CLI with npm. This gives us access to `elm-repl` and `elm-reactor`. The repl lets us play with expressions at the command-line, and reactor starts a development server which builds Elm files on-demand.

Install the Elm Platform command-line tools

This lesson shows a super simple, yet pleasant, look at the smallest Elm example. We will use the text function from the Html module to display text in a browser.


Output text in a browser using the text function in Elm

A record is a set of key-value pairs, similar to objects in Javascript. Record fields can be accessed through dot-notation, or special access functions. Records are fully type-checked and can be described by type aliases.

Store key-value pairs using Records in Elm

Functions are one of the core building blocks of Elm. In this lesson we learn how to define, call, pass parameters, receive parameters, partially apply functions, compose functions, and add correct type signatures. In this lesson we will show how to define functions with type signatures.

Write functions and Type Signatures in Elm

Elm provides a declarative way to produce DOM elements and react to DOM events, similar to HTML. Learn how to get Web content on the screen by writing functions that take in data and return Elm’s version of HTML.

Render HTML in the browser using the Html module in Elm

Sometimes a function is useful for many different types. Instead of writing a copy of that function for each different type, learn to use type variables and allow the same function to be reused.

Reuse Functions Through Type Variables in Elm

Elm is designed specifically for building applications, and it is built around a scalable and sensible application architecture. Learn the very basics of this architecture through updating application state by reacting to DOM events.

Create Apps Using the Elm Application Architecture

Elm comes with an index of publicly-usable open-source packages. Using packages from this index can substantially improve a developer’s experience. Learn how to find a package through the index, understand its API through type annotations and documentation, download it, and use it in a project.

Elm packages aren't working with embedded **Ellie**, so I've provided you with a link to the Ellie example [here](https://ellie-app.com/nNVB6RrbZa1/9). 

Discover New Packages Using the Elm Package Index

In this lesson we'll create a very simple application dispatcher utilizing the open source flux dispatcher from Facebook.

Flux Architecture: Application Dispatcher

In this lesson we'll create our Flux application's store which will manage the state of our application.

Flux Architecture: Application Store

In this lesson we'll create our initial components using the architecture we've built so far.

Flux Architecture: Components/Views

In this lesson we'll shift the responsibility of managing the state of our application over to a higher-order component rather than having each component managing it's own state.

Flux Architecture: Higher-Order Components

In this lesson we'll organize our components by feature.

Flux Architecture: Project Organization

Using our established architecture we'll make short work of a few remaining tasks to meet our application requirements.

Flux Architecture: Component Wrap Up

In this lesson we'll simplify future development by reducing the logic contained in our application's store.

Flux Architecture: Dumb Stores

Elm includes a data type called `Maybe` which is useful for working with values that may, or may not exist. This lesson shows a simple case where maybe types are encountered, and how to make them useful.
