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...
Application Performance Monitoring (APM), as the name suggests, is the process of monitoring the performance of the many aspects of your application. When an end-user logs into your application, for even just one web page to load on their device, there are very many backstage components that need to come together and operate in synchrony to ensure a smooth and fast experience. These include network components (that carry the bytes of data), software components (e.g., server-side frameworks, front-end code, and other dependencies), and hardware components (i.e., CPU processors, memory, and storage of machines that host your web servers, APIs, databases, file systems, etc.) It can become overwhelming to manually keep track of your application performance on all these different levels and across all components. This is even truer when you ideally want monitoring and checks to happen all the time, in real-time! Well, this is precisely the problem that APM solutions target. APM tools, like ScoutAPM, allow organizations to get a detailed analysis of the performance of your applications, in real-time. This includes critical information about server requests, response times, time-consuming methods and end-points, errors and their root cause analysis, and lots more – presented in a way that is easy to understand and troubleshoot. These performance insights provide a lot of valuable information about optimizing resource allocations and effective cost reductions while surfacing other issues that could potentially fail your application – and all before the user gets a hint of anything being amiss. Apart from presenting a bird’s eye view of what is happening within your application as a whole, APM tools provide you with your application’s...

This article was originally published at strilliant.com — please give some love to the original! ❤Separating your frontend and backend has many advantages: The biggest reason why reusable APIs are popular — APIs allow you to consume data from a web client, mobile app, desktop app — any client really. Separation of concerns. Long gone are the days where you have one monolithic-like app where everything is bundled together. Imagine you have an extremely convoluted application. Your only option is to hire extremely experienced/senior developers due to the natural complexity. I’m all for hiring juniors and training your staff, and that’s exactly why you should separate concerns. With separation of concerns, you can reduce the complexity of your application by splitting responsibilities into “micro-services” where each team is specialized in their micro-service. As mentioned above, the on-boarding/ramp-up process is much quicker thanks to splitting up responsibilities (backend team, frontend team, dev ops team, and so on) Forward thinking and getting started We will be building a very powerful, yet flexible, GraphQL API based on Nodejs with Swagger documentation powered by MongoDB.The main backbone of our API will be Hapi.js. We will go over all the technology in substantial detail.At the very end, we will have a very powerful GraphQL API with great documentation.The cherry on top will be our integration with the client (React, Vue, Angular) Prerequisites NodeJS installed Basic JavaScript — if you feel wary, check out this article for the best courses to brush up on your JavaScript game Terminal (any will do, preferably bash-based) Text editor (any will do) MongoDB (install instructions here) — Mac: brew...
