Add Web UI

[mperham]

Sidekiq's Web UI is based on Sinatra. Investigate building a native Crystal version using Kemal and ecr views instead.

Requires #11.

I'd be happy to help you about any Kemal related question 👍

The top-level DSL seems really cool at first glance but IMO it takes away a lot of capabilities. I'm really missing a more idiomatic OOP-based webapp style. Sinatra now provides something like this:

class Sidekiq::Web < Kemal::Base
  public_folder "..."

  get "/" do |env|
  end
end

# Allow multiple webapps to be mounted
Kemal.serve("localhost", 8080, {
  "/sidekiq" => Sidekiq::Web
  "/something-else" => Another::Web
})

With that style, you could also implement testing helpers, a la Rack::Test:

require "kemal/spec"

def app
  Sidekiq::Web
end

describe "web" do
  it "should work" do
    resp = app.route(:get, "/")
    resp.code.should eq(200)
  end
end

Yeah, i'm pretty aware of that and would like to implement the classic Sinatra style which lets you mount multiple apps.

Done!

I was able to implement GET and POST helper methods to make the Ruby port easier. Allows me to spec like this:

    post "/scheduled/#{job_params(*params)}", {"add_to_queue" => "true"}
    assert_equal 302, last_response.status_code
    assert_equal "/scheduled", last_response.headers["Location"]

    get "/queues/default"
    assert_equal 200, last_response.status_code
    assert_match(/#{params.first["args"][2].to_s}/, last_response.body)

# Allow multiple webapps to be mounted
Kemal.serve("localhost", 8080, {
  "/sidekiq" => Sidekiq::Web
  "/something-else" => Another::Web
})

Did this get implemented in a mountable way for Kemal? I've been writing Rails-like controllers with Kemal in danielpclark/crystal-rails-template

require "../app/controllers/*"

module Railslike
  module Routes
    include Controllers
    get "/", &IndexController.to_proc
    error 404, &Error404Controller.to_proc
  end
end

Where each method I define (to_proc in this instance) returns something like:

def self.to_proc
  ->(env : HTTP::Server::Context){
    controller = new(env)         # Evaluated in other controller context of type BaseController
    controller.render(controller) # Pass context into layout renderer
  }   
end 

This works very well for me. But I digress, has this been implemented to run Sidekiq mounted in an existing server instance of Kemal?

@danielpclark unfortunately, this is not implemented. Kemal only allows single app per single process (for now)
