Replace JavaScript with Ruby

I’ve spent the little time I’ve had spare this past week fiddling with this project and have made surprising progress!

Using OpalRB, Mithril, and Bulma I have built an extremely nice way to build interactive browser applications. The payload is a little heavy off the bat but I feel the improved developer experience is worth it for what I’m doing, which is mostly distributing desktop applications where the penalty for larger files is greatly reduced.

I’m currently making this a gem and giving a serious test by implementing a real project using it. I’m creating more widgets for my writing streamer widget pack. I’ve only just got it to the point where I’m seriously implementing something but so far I’m excited. The following is the code for the Counter components you see below.

Mithril::Component.define(:Counter) do
  oninit do
    state[:count] = 0
  end

  view do
    nav(class: "card") {
      header(class: "card-header") {
        p(class: "card-header-title") {
          plain "Counter"
        }
      }
      div(class: "card-content") {
        div(class: "block") {
          plain "Current count: #{state[:count]}"
        }
      }

      div(class: "card-footer") {
        a(
          class: "card-footer-item",
          onclick: ->(e) {
            e.JS.preventDefault
            state[:count] -= 1
          },
          href: "#"
        ) { plain "-" }

        a(
          class: "card-footer-item",
          onclick: ->(e) {
            e.JS.preventDefault
            state[:count] = 0
          },
          href: "#"
        ) { plain "Reset" }

        a(
          class: "card-footer-item",
          onclick: ->(e) {
            e.JS.preventDefault
            state[:count] += 1
          },
          href: "#"
        ) { plain "+" }
      }
    }
  end
end

Needless to say I’m very excited by this and it has kept programming fun during some hard times. If nothing else I think that’s incredibly valuable. I’ll release the code at some point for the gem I’m building but that probably won’t be for a while.
