ruby - Serving static files with Sinatra

Question

I have one page website only using HTML, CSS and JavaScript. I want to deploy the app to Heroku, but I cannot find a way to do it. I am now trying to make the app working with Sinatra.

.
|-- application.css
|-- application.js
|-- index.html
|-- jquery.js
`-- myapp.rb

And the following is the content of myapp.rb.

require 'rubygems'
require 'sinatra'

get "/" do
  # What should I write here to point to the `index.html`
end

Answer 1

You can use the send_file helper to serve files.

require 'sinatra'

get '/' do
  send_file File.join(settings.public_folder, 'index.html')
end

This will serve index.html from whatever directory has been configured as having your application's static files.
