Key features of Rails Framework

Active Record, within the Rails framework, functions as an Object-Relational Mapping (ORM) library. This means that developers can interact with databases using Ruby classes rather than writing raw SQL. By leveraging Active Record, working with databases becomes more straightforward, enabling developers to concentrate on the business logic of their web applications without the need to be overly concerned about database interactions.

Action Controllers play a pivotal role in managing the flow of data between the Model and the View. These classes handle user requests, process them, and return responses. Additionally, Action Controllers manage crucial application logic such as authentication and authorization.

Action Dispatch takes charge of routing requests to the appropriate Action Controller. By utilizing a routing table, Action Dispatch maps URLs to controllers and actions, providing developers with an efficient way to associate URLs with specific controllers and actions in their applications.

Action Views are responsible for rendering the views of the application. They play a key role in presenting data from the model to the user and can be written in various languages, including Ruby, HTML, and JavaScript.

Scaffolding, a notable feature of Rails, expedites development by allowing developers to swiftly generate boilerplate code for their applications. This feature is particularly handy for creating the foundational structure of a Rails application, including models, views, controllers, and database migrations. Scaffolding serves as a valuable time-saving tool, enabling developers to kickstart their projects without the need to write extensive boilerplate code. 

Hosting Ruby on Rails applications 

Hosting your Rails application offers various options, both free and paid.

A popular approach involves leveraging cloud hosting providers such as AWS (Amazon Web Services), Google Cloud, or Microsoft Azure. These services present a plethora of choices, ranging from virtual machines to containers and serverless computing, catering to the diverse needs of your application. Moreover, they offer tools for administration, monitoring, and integration with services like load balancers and databases.

Alternatively, you can opt for a Platform-as-a-Service (PaaS) provider like Heroku or Cloud Foundry. PaaS providers manage infrastructure and scaling, providing user-friendly interfaces for deploying and overseeing your application. While simpler to set up and manage compared to cloud providers, PaaS solutions might entail less control or flexibility.

Regardless of your hosting choice, it's imperative to ensure your web application is configured for production use. Tasks include setting up a database, implementing a reverse proxy, and fortifying your application for security and scalability to handle increased traffic. 

API’s in Rails

Thanks to the inherent support for RESTful routing and controllers in Rails, creating an API becomes a straightforward process. Representational State Transfer (REST) is an architectural design for developing online services, grounded in the guiding principles of both the web and HTTP.

To initiate API development in Rails, you start by establishing a new Rails web application with the —API parameter. This setting configures your application to utilize a basic set of middleware tailored for API-only applications, excluding any middleware used for processing web requests like cookies and sessions.

Subsequently, you design your API controllers and routes. The RESTful routing in Rails simplifies the connection of URLs to controllers and actions, providing a standardized and cohesive structure for your API. For example, you can allocate one route for resource creation with POST /resources and another for resource retrieval with GET /resources/:id.

Once your routes and controllers are configured, you can commence building the functionality of your API. Rails' built-in support for managing JSON and XML data streamlines the handling of requests and responses. Additionally, you can seamlessly interact with your application's database using Rails' ActiveRecord, facilitating access, creation, updating, and deletion of records.

What exactly are ruby gems?

A gem refers to a bundled collection of interconnected files, libraries, and code that constitutes a software application. Easily installable and maintainable through the Gem command-line utility, gems serve to enhance the functionality of Ruby or Rails applications. It functions akin to package managers like NPM for JavaScript or PIP for Python.

In the context of Rails applications, gems offer a spectrum of capabilities, including:

Additional Libraries and Features: Gems can introduce new libraries and features to the Ruby language.

Rails-specific Functionality: Gems can provide functionality unique to Rails, such as supporting various database systems or managing file uploads.

Integrations with Third-party Services: Gems facilitate integrations with external services, enabling actions like sending emails or utilizing APIs.
