ruby - middleman - asset path for CDN at build time

Question

I want to do the following

if build?
    assetPath = "//cdn.domain.com/assets"
else
    assetPath = "assets"
end

trying all combinations and reading everywhere but simply stumped at the moment

ruby and middleman - still learning.

Answer 1

你在尝试这个config.rb吗？如果没有，你应该这样做。

已经有一个您可能想要使用的设置...

set :css_dir, 'assets'

...并在构建时更改：

configure :build do
  set :css_dir, '//cdn.domain.com/assets'
end

您知道资产助手吗？您可以使用 ...

<%= stylesheet_link_tag 'foo.css' %>

...在您的 (ERB) 模板中。

在开发时应该给你...

<link href="/assets/foo.css" media="screen" rel="stylesheet" type="text/css" />

...在您的构建中：

<link href="//cdn.domain.com/assets/foo.css" media="screen" rel="stylesheet" type="text/css" />

Answer 2

我实际上对早期答案有疑问。要实际更改资产路径以使用 CloudFront 等 CDN，我必须执行以下操作：

# Fingerprint assets
activate :asset_hash

# Enable Asset Hosts
activate :asset_host

set :asset_host do |asset|
  '//d23xxk856.cloudfront.net'.to_s
end
