Ember.js is a JavaScript framework for building scalable web applications with discrete components.

In this course, practicing JavaScript developers will be introduced to the Ember.js framework. You’ll start by setting up Ember and creating a project application. You’ll continue with the building blocks of Ember.js, including templates, components, routing, services, helpers, Ember Data, and testing. You’ll then use the components to build a complete e-commerce application from scratch. Each lesson will add more depth and functionality to your application with hands-on exercises. Finally, you’ll integrate the application with Firebase.

By the end of the course, you’ll be prepared to leverage Ember’s key features to develop robust web applications.

Developing Robust Web Applications with Ember.js

# What is Ember Data?
Ember can be used with any backend, such as JSON:API, REST, GraphQL, and more. **Ember Data** provides us with a robust set of tools to handle and manage the application data. It’s used to format the server requests, normalize the responses, and efficiently manage the local cache of data.


             

# Ember Data models
The idea behind Ember Data is to organize our application into model objects. **Ember Data models** are the objects that are the representational units of information. We have to design these models according to the requirement of our application. For example, in a fully developed online shopping application, we might have a model for an item, cart, invoice, and so on.

Models tend to be persistent. This means that no data is lost when the user closes the browser window. Unlike most server load models, Ember uses other efficient methods, such as using `IndexedDB`, to store data on the user’s hard drive. We can specify a model of the route that loads the data from memory into the component. Ember Data makes managing models much easier and more efficient.

# Store
Imagine a case where we want to show the same information on two separate components. In most web applications, two separate requests will be made for the same information, increasing the bandwidth cost to fetch redundant data. Ember Data solves this problem by providing us with a single store for the whole application. The store is a central repository of models in our application. Different routes and their controllers can ask the store for models, and the store is responsible for fetching them.

# Records
An instance of a model loaded from the server is known as a **record**. We can create records of a certain model and save them to the server. A record is identified by its model and a unique ID. For example, if we want to search for a record of a model named `item`, we use the command below:

```
this.store.findRecord('item', 1);
``` 
This specific record is identifiable by its model named `item` and its ID, which is `1`.

# Adapters
The **adapter** is responsible for translating a request from Ember into a server request. For example, if our e-commerce application asks for a specific product with a product ID of `1`, the adapter determines whether Ember should load it over HTTP or a WebSocket. If it’s HTTP, the adapter determines whether to use the `/item/1` or `/resources/item/1` as URL. When a record that isn’t present in the store is requested, the adapter is responsible for making it available. If a record is updated, the store delivers it to the adapter that sends and saves it to the server. Ember provides us with several built-in adapters for different types of servers. By default, Ember Data is configured to work with JSON:API. If we need to integrate our application with a server that doesn’t have an adapter available, we can manually configure our application to work with any data our server returns.
