Learn Ember, Flux-architecture and Twit

In this course we’ll learn how to create Twitter bots. We’ll first learn how to interface with the Twitter API using Twit.js, which allows us to post statuses, search tweets, and interact with followers. We’ll create several example bots that show the diversity of possibilities, using powerful tools such as RiTa.js, Google’s Cloud Vision API, and Tracery. We’ll learn how to tweet data from Google Spreadsheets, and to compose and tweet a song for an audio bot. We’ll also learn how to host our bot logic on Heroku and Docker. 

Twitter API Client for node

Supports both the REST and Streaming API.

Ember is a javascript framework that provides a rich set of tools for building modern web applications. Unlike many frameworks, Ember comes with opinions and a way of doing things so you aren't left with a ton of decisions to make about problems that have already been solved very well. Ember was designed from the start to deliver a productive and comfortable experience for you, the developer.

In this course you will learn what you need to know to get started building your own Ember we applications. From the absolute essentials like creating a new project with the Ember-CLI tools, templating, routing, and reusable components.



A JavaScript framework for creating ambitious web applications.

Ember 2 Fundamentals

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)

Components in Ember are great for reusing code throughout our application. We’ll see how each instance of an Ember component has isolated state and we can over ride as well as set default values.

In this lesson, we will learn how to make a simple, reusable component within an Ember application.

Create Simple Components in Ember

In this lesson, we learn how to create nested routes and templates in an Ember.js application, in addition to how to create nested routes and isolated templates.

Creating nested routes in Ember.js

In this lesson, we will learn how templates work within Ember and how to use HTMLBars. This lesson will cover the connection between controllers and templates and how to use actions within templates as well.

Ember Templating with HTMLBars

In this lesson, we will learn how to install Ember Inspector and use it to see the state of our application and debug it.

The Ember Inspector can be installed from the [Chrome Web Store](https://chrome.google.com/webstore/detail/ember-inspector/bmdblncegkenkacieihfhpjfppoconhi). We will see how the inspector gives us access to information such as the routes available to us, the components used in a particular view, and data that is exposed to us etc.


Debug Ember Applications using Ember Inspector

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

We’ll get a real-time stream of tweets, and learn how to filter a stream by keyword, location, and user.

Use the Twitter Stream API with Twit.js

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 Ember.js, functions that are executed through user interaction with your application are called actions, which can be defined at the route, controller, or component level. In this tutorial, we look at a simple example of defining actions on the controller and hooking it up to our template in order to update properties on the controller.

Add user interaction to Ember.js apps using actions

We will learn how to install Ember-CLI and use it to create a new Ember project. We will also learn how to run the Ember project.

Create an Ember Project with the Ember-CLI

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

Flux Architecture: Application Actions

In this lesson, we show how to specify a model for an Ember Route so its data can be displayed. 

Define Models for Routes in Ember

In this lesson we will create an `updateContent` method that sets the value of our `content` property to the current epoch timestamp. We need to call `toString()` on the `Date.now()` method in order to make TypeScript happy.

```
updateContent() {
  this.content = Date.now().toString()
}
```

We create a constructor that takes the options parameter, call `super(options)` and call into our `this.updateContent()` method.

```
constructor(options) {
  super(options)
  this.updateContent()
}
```

When we refresh our page we can see that the value of `content` is set to the epoch timestamp. 

To make the content really dynamic we use `setInterval()` to call into `updateContent` each second: `setInterval(() => this.updateContent(), 1000)`.

When we save our file we see that our content does not get updated anymore and when we check the console we see that we get an error telling us that: The 'content' property on the my-component component was changed after it had been rendered. The error also informs us that we should Use the @tracked decorator to mark this as a tracked property.

We add the @tracked decorator to our property, we import tracked from @glimmer/component and we refresh the page. We verify that `content` gets updated each second.

We change our `updateContent` to add our the timestamp to the array. When we use `this.items.push(this.content)` to achieve this we see that the list does not get updated. This is because the `@tracked` decorator only tracks the re-assignment of properties.

The way to get this working is by re-assigning our `items` array inside `updateContent`. We assign a new array, de-structure the current items array and add the new content.

```
this.items = [...this.items, this.content]
```
