Learn Flux-architecture, Purescript and React-storybook

PureScript is a small strongly, statically typed language inspired by Haskell and compiles to JavaScript. This means no run-time errors, human readable output, ADTs, and pattern matching (and more!) all at your fingertips.

In this course we will use an [online editor](http://try.purescript.org/) to show basics into PureScript with an instant visual representation, investigate the type system and ways to reason about common programing problems with PureScript. 

As we explore the type system and common problems that are faced when programming in PureScript we will learn plenty of functional programming concepts as PureScript is a purely functional language.

PureScript is a small strongly typed programming language that compiles to JavaScript.

Functional Programming Concepts in Purescript

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)

Storybook is a UI component development environment for React, Vue, and Angular. With that, you can develop UI components without running your app.

Here I show how best to configure a React Storybook to use [Typescript](/q/typescript) (with TSX). This lets you write your reusable components with maximal type safety. Please see the provided code for the full source.

Configure React Storybook for use with Typescript

In this lesson, we'll see how we can get JSON decoding for free in PureScript using the Simple-JSON library. Because PureScript is a pretty powerful language, we can just declare what type we want the result to go into and get it for free!

[Storybook](https://storybook.js.org/) is a framework that allows you to develop components in isolation. It is ideal for a variety of use cases, most commonly when you're building some shared component toolkit. As such, Nx comes with a dedicated package `@nrwl/storybook` that adds a series of useful code generators to add storybook to an existing React library, but also to automatically generate stories and more.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

[Nx](https://nx.dev) combines a lot of the best tools on the market, integrates them, and provides tooling to provide the best possible developer experience. One such pair is [Cypress](https://www.cypress.io/) and [Storybook](https://storybook.js.org/). Storybook allows developing components in isolation, which is also a great basis for testing components, which is where Cypress shines.
In this lesson, we're exploring some of the `@nrwl/storybook` code generation utilities that allow you to not only configure Storybook for a React application but automatically also set up a Cypress test configuration for it along with some spec files generated from the Storybook stories.

Use Cypress and Storybook to test your React Components in Isolation

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

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

In this lesson, we show how to setup React Storybook into an existing React project. We’ll go through common configuration files and how to adjust them.

Add React Storybook to a Project 

Components trigger actions via function props to notify of events that occur within the Component. We can inspect those events using React Storybook.

Inspect Component Events with React Storybook

In this lesson we'll build our actions which will be sent to our dispatcher.

[React Storybook](https://github.com/kadirahq/react-storybook) is a UI component development environment for React.
With that, you can develop UI components without running your app.

Here I show how to get started with React Storybook.
For more information, have a look at our [documentation](https://getstorybook.io/docs).

Getting Started with React Storybook

React Component stories can be dynamically loaded into React Storybook instead of doing it manually every time.

Load React Storybook Stories Dynamically

In this lesson we'll introduce routing into our application using react-router 1.0

Flux Architecture: Routing with react-router 1.0

Story is the smallest unit of React Storybook. A story describes a React Component, and its various states and variations. Stories can describe complex components with dynamic properties and data loaded from a service. In this lesson we will write our first React Storybook story.
