Q & A

What is Ember.js?

Ember.js is a productive, battle-tested JavaScript framework for building modern web applications. It includes everything needed to build rich UIs that work on any device.

Why should developers choose Ember.js over other UI frameworks?

Developers might choose Ember.js because it is used by major companies like Apple, Microsoft, and Netflix. It is easy to learn, has a powerful CLI, and offers a robust data management system. Additionally, it has a large community and extensive documentation.

What is the key feature of Ember.js that makes it suitable for large-scale web applications?

Ember.js is suitable for large-scale web applications due to its strong CLI tools, data management capabilities, and the ability to handle complex client-side logic and communication with the server.

What is the structure of an Ember.js application?

The structure of an Ember.js application includes several important folders: the 'app' folder (which holds the logic, templates, and styles), the 'config' folder (for configuration settings), the 'public' folder (for static files like images), the 'test' folder (for testing), and the 'vendor' folder (for third-party libraries).

How do you set up an Ember.js project?

To set up an Ember.js project, you first need to install Node.js and Ember CLI. Then, you can initialize the project using the command 'ember init', which will create the basic structure of the app and install dependencies.

What is the purpose of the 'ember serve' command?

'ember serve' is used to start the Ember.js application locally. It compiles the files and hosts the application on a local server, typically accessible at 'localhost:4200'.

What is the significance of using Bootstrap and Font Awesome in Ember.js?

Bootstrap and Font Awesome are used to enhance the visual appearance of an Ember.js application. Bootstrap provides responsive design elements, while Font Awesome offers iconography that can make the app more visually appealing.

What is Handlebars, and how does it relate to Ember.js?

Handlebars is a templating language that Ember.js uses for creating dynamic HTML. It allows for embedding logic within HTML templates, which makes rendering dynamic content easier.

How do you use SASS with Ember.js?

To use SASS in Ember.js, you need to install the 'ember-cli-sass' package and configure the project to support SASS files. Once set up, you can write styles using the SASS syntax, which will be compiled and applied to the application.

What will be covered in the next tutorial?

In the next tutorial, the focus will be on the Ember.js routing system, which is crucial for managing how users navigate between different pages of the application.
