With the recent release of version 6.1, Ruby on Rails now supports the rendering of objects that respond to render_in, a change we introduced to the framework. It may be small (the two pull requests were less than a dozen lines), but this change has enabled us to develop a framework for building encapsulated views called ViewComponent. Why encapsulation matters Unlike models and controllers, Rails views are not encapsulated. All Rails views in an application exist in a single execution context, meaning they can share state. This makes them hard to reason about and difficult to test, as they cannot be easily isolated. The need for a new way of building views in our application emerged as the number of templates in the GitHub application grew into the thousands. We depended on a combination of presenters and partials with inline Ruby, tested by expensive integration tests that exercise the routing and controller layers in addition to the view layer. Inspired by our experience building component-based UI with React, we set off to build a framework to bring these ideas to server-rendered Rails views. Enter ViewComponent We created the ViewComponent framework for building reusable, testable & encapsulated view components in Ruby on Rails. A ViewComponent is the combination of a Ruby file and a template file. For example: test_component.rb class TestComponent < ViewComponent::Base def initialize(title:) @title = title end end test_component.html.erb <span title="<%= @title %>"> <%= content %> </span> Which is rendered in a view: <%= render(TestComponent.new(title: "my title")) do %> Hello, World! <% end %> Returning: <span title="my title">Hello, World!</span> Unlike traditional Rails views, ViewComponent templates are executed within the context of the ViewComponent object, encapsulating their...
Setting up a project with Ruby on Rails, PostgreSQL and GraphQL is actually pretty straightforward. But first, some prerequisites. For this tutorial (tested on versions 2.7.3, 6.1.4.1 and 11.0 respectively), you must have all three, Ruby on Rails, PostgreSQL and GraphQL installed on your development machine. Some general knowledge of Ruby and Rails is also recommended. Before we begin, however, you might be wondering why anyone would want to replace the perfectly fine experience provided by the traditional REST API with one offered by GraphQL. Well, one obvious reason is that GraphQL deals quite elegantly with resources over- and under-fetching. With GraphQL you are given the exact information you request – nothing more, nothing less. Moreover, it is almost self-documenting, making that one less item on your list of things to worry about. And there are other pros to GraphQL, such as it being both strongly typed and language and database independent. But in the meantime, I’ll leave those for you to explore on your own. So, without further ado, let’s set up our first GraphQL API on Ruby on Rails. Setting Up GraphQL for Rails Step 1 – PostgreSQL database Let’s create a Ruby on Rails API app with PostgreSQL as the database. We’ll be making a very simple bookshelf API. Step 2 – GraphQL to Gemfile Let’s add GraphQL to our project. To do so, add gem ‘graphql’ to your Gemfile. For testing your queries in development, add gem ‘graphiql-rails’ under the development category. Now, let’s install our gems. Make sure that your config/routes.rb includes the following: Step 3 – Create database Time to create the database...
When it comes to building a new website/app or updating the existing one, it is essential to know the difference between a web designer and a web developer, whose goals may seem a bit similar at the first glance. Although these two positions relate to building a website or a product and can use the same tools, their roles are distinctive in the terms of goal achievement. So let’s dig in and break down each role in detail, so you can easily figure out which one will best suit your project. A web designer: takes care of feel and look A web designer is a person who is responsible for layouts and the visual aspect of your product, as well as for the interaction between different pieces and parts in order to provide a user with usability and seamless flow. Web designers do not build a website – they make prototypes, wireframes (let’s say they craft ideas in a beautiful way) to help developers proceed with the implementation. In essence, a designer is like an architect who focuses on technical aspects such as wireframes, code, content management. However, a great design is not about the integration of all visual elements into functionality – it is rather about adhering to the design process, which results in feasible products that are ready to be worked on by the developers’ team. In order to conceptualize the product and make it stand out from the crowd, a designer has to stay updated on the latest design trends and follow best practices. User persona must be an essential part of a designer’s research before...

This was valid in 2018 and can even be valid in 2019 … Programming Languages Learning JavaScript...
Ruby on Rails (or “Rails”) is an open-source web application development framework written in the Ruby programming language. It’s one of the most popular Ruby libraries and one of the top reasons developers choose to learn Ruby. Modern web applications can be very complex with many layers. Rails makes web development easier, providing a pre-built structure for development and everything you need to build a web app. In this article, we’ll look at what Rails is used for, its advantages and disadvantages, and what jobs you can get if you know this framework. Then, we’ll show you how to get started using it to build your own web apps. What is Ruby on Rails used for? We explained that Ruby on Rails is a web framework, but it helps to know what a web framework is to know just how powerful a tool like Rails can be. A framework simplifies the creation of web applications. It does this by providing default structures for your code, any databases you use, and the web pages the application will serve. You can think of a framework almost like Legos. With a framework, you get pre-built “Legos” of code that you can mix, match, and modify to build a custom web application, which means you don’t have to create everything from scratch. Ruby on Rails uses the Model-View-Controller (MVC) architectural pattern used by many other web frameworks — one of the most well-known patterns in development. The MVC pattern separates a web application’s code into three interconnected parts: This pattern makes Rails very flexible and useful for all types of web applications. Rails...
