Ember.JS and Ember CLI and Ember Data

Ember: An in-depth look at its tools

The Ember Development toolkit consists of two things, the Ember CLI and the Ember Data component, both which are crucial for Ember application development. Both are also obtainable when installing Ember into your system. In this blog, we will be taking a deeper look into what each of these tools do for your application and we will take a behind the scenes look to know what they are made of.

Ember CLI, The Command Line Interface

Ember CLI is a command line utility that offers good if not great conventional project structure when creating your applications, a Broccoli-powered pipeline and it also offers extensions to fit the need of your development.

Ember CLI was developed with a strong support system that consist of Handlebars and HTMLBars, SASS and Compass, as well as LESS and Stylus. All which offer great CSS utilization such as SASS giving you CSS on steroids and LESS allowing backward compatibility with your CSS files in your application so you will always be able to continue to use your older formats and update them as you need to. And as mentioned before the add-on system Ember CLI provides is able to provide reusable code and extend your building tools when developing applications.

Ember CLI also has Babel baked into it, Babel is a Javascript compiler that uses the ES2015 syntax for Javascript, it is a syntax that updated the way Javascript works by implementing new techniques and uses, it offers better classes when implemented by making class patterns easier to use in development of the application, they support super calls, static methods, constructors amongst many others. It also offers Enhanced Object Literal functions which creates better objects, and Template Strings that are able to avoid injection attacks and allows for string construction to be optimized.

As for Ember CLI uses when creating an Ember application, it is able to automatically import all the modules needed for the project, for example if you had a route, Ember CLI would find the source file at routes/emberProj.js which in turn would lead Ember CLI into knowing that it needs to load the controller found at controller/emberProj.js and the template in templates/emberProj.hbs. This gives you a strong and smart development tool kit that is able to recognize all the files you need to work and update automatically without the need to create or update these files as the project grows on.

Ember Data, the persistence Data library

Ember uses Ember Data in all of it’s models, what this offers is a robust way to manage the data in Ember models for your applications. Ember Data was designed to be the underlying persistence mechanism of the application, and it works perfectly with other languages such as JSON, WebSockets and or other local DB storage. It offers server-side class functionalities that can be implemented into a Javascript Environment with ease.

Ember Data also uses Promises when you first start your application to manage loading and saving records into Javascript, Promises are a tool for handling asynchronous communication from the application and the code. It is most commonly used in Ember but offers compatibility with other languages as well.

When the API is represented with Ember Data, the models, and adapters all become a field name, this encapsulates level of details between each association, this insulates your code from making changes to itself, this also insulates your code even more from being affected by the backend since Ember utilizes its own models and not JSON or XML, etc.

Ember Data and Ember CLI installation

To install both the CLI and Ember Data, you will Node’s NPM, first to install Ember CLI, this is done by installing the latest version of Node.JS, the LTS version and then running the following command in the Command Prompt from windows: npm install –g ember-cli. This will install Ember CLI into your computer and from then on you can start your own Ember Projects.

To install Ember Data, you will need to do it after Ember CLI is installed because you run the command thru Ember CLI, and the command is: ember install ember-data. This will install Ember Data in your system for future utilization. You could also install older version of Ember Data with Node NPM with this command: npm install ember-data@2.2.1 –save-dev. This installs an older instance of Ember Data outside of Ember CLI.

So in Conclusion

Throughout this blog we have taken a look at Ember CLI, and what it offers as a development toolkit in the development of Web Application, as well as other syntaxes baked into the CLI. We have also taken a look at Ember Data and it’s persistence Library that is able to hold the data of the models and adapt it throughout the application it will be used for. We have also gone over how to install Ember CLI and Ember Data into your system as well in case Ember.JS has caught your interest.

Thank you for taking your time reading my blog, if you haven’t already, I have written a blog about the Ember.JS basics that can be found here as well if you’d like more insight into this language.
