Sinatra AssetsLinker Helper

Provided methods:

• css_uri(file_name, add_script_name = true)
• js_uri(file_name, add_script_name = true)
• img_uri(file_name, add_script_name = true)

They extend the uri method from the Sinatra. Always returns relative paths, unless you set :project_cdn_url.

Installation

Add this line to your application's Gemfile:

gem 'sinatra-assets_linker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sinatra-assets_linker

Configuration

Through SinatraAssetsLinker::Config class:

config = SinatraAssetsLinker::Config.new(
  "project_css_dir" => "css_dir"                    # default: "stylesheets"
  "project_javascripts_dir" => "js_dir"             # default: "javascripts"
  "project_js_compressed_dir" => "cjs_dir"          # default: "js"
  "project_images_dir" => "img_dir"                 # default: "images"
  "project_assets_verbose" => true                  # default: false
  "project_cdn_url" => "http://cdn.net"             # default: nil
)

Usage

Above methods look for configuration under: settings.assets_linker_config, so:

require 'sinatra/base'
require 'sinatra/assets_linker'

class MyApp < Sinatra::Base
  helpers Sinatra::AssetsLinker

  configure do
    set :assets_linker_config, SinatraAssetsLinker::Config.new(ENV.to_h)
  end
end

and when you call:

css_uri('file.css')       # -> /css_dir/file.css
js_uri('file.js')         # -> /js_dir/file.js
img_uri('file.jpg')       # -> /img_dir/file.jpg

if you set "project_cdn_url" before, you get:

css_uri('file.css')       # -> http://cdn.net/css_dir/file.css
js_uri('file.js')         # -> http://cdn.net/js_dir/file.js
img_uri('file.jpg')       # -> http://cdn.net/img_dir/file.jpg

Assets verbose

If you set "project_assets_verbose" to true, then the js_uri method will use project_javascripts_dir instead of project_js_compressed_dir
