What is Code Q&A built with?
Code Q&A was built with Ruby on Rails! And it's server rendered!
More specifically:
I've used many, many frameworks and tools to build Web Applications over the years.
On the backend and full-stack in mostly chronological order:
CGI, Zendframework, Drupal, Django, Flask, Spring, Dropwizard, Rails, Sinatra, ExpressJS, NestJS, NextJS
And on the front-end:
Vanilla JavaScript, JQuery, Bootstrap, Backbone, Semantic UI, Angular, React
and I'm probably forgetting some ... 🤔
And the truth is ... most of them are pretty similar. Each successive framework tries to solve some of the problems of the previous frameworks but they inevitably introduce new problems or reintroduce old problems. And they always claim to solve all of your problems ... but they don't.
I've used Rails professionally at multiple companies and on many side projects so I know it pretty well by now.
Rails is great because it helps me ship new features very quickly, it has a ton of batteries included. And I can focus on the product instead of making trivial decisions or writing a bunch of boilerplate.
Most of the time I end up building my side projects with whatever tools I've been using the most. For a while, I used Python frameworks like Django, then I used Node and React, and in between I used Rails.
I've had a bit of a personal "server rendered" renaissance lately so for sites like Code Q&A, which is mostly a bunch of independent static, non-interactive pages, I like to use Full-stack Rails and only sprinkle in JavaScript when needed.
If Rails sounds interesting, and you don't have experience in something else, give it a shot! If you have experience with something else, go with that. With technology, you should "Go with what you know" ... unless you just want to learn something new.
