在Heroku服务压缩资产与机架Zippy [英] Serving Compressed Assets in Heroku with Rack-Zippy

问题描述

我按照本教程介绍了如何压缩Heroku中的资源。

http://www.cheynewallace.com/serving-compressed-assets-with-heroku-rack-zippy/

这是我的Application.rb文件

  require File.expand_path '，__FILE__）
 
需要'rails / all'
 
 Bundler.require（* Rails.groups）
 
模块博客
类应用， Rails :: Application 
 
 config.assets.precompile + =％w（*。png * .jpg * .jpeg * .gif）
 config.exceptions_app = self.routes 
 
 config.cache_store =：memory_store 
 Rails.application.config.middleware.swap（ActionDispatch :: Static，
 Rack :: Zippy :: AssetServer，Rails.public_path）
 
 end 
 end 
  

我的Gem文件

  gem'yui-compressor'，'〜> 0.12.0'
 gem'rack-zippy'
  

我运行heroku运行rake中间件得到以下输出

 使用Rack :: Sendfile 
使用Rack :: Zippy：AssetServer 
  

现在，当我访问开发人员工具和网络选项卡时，我发现大小与每个资产的内容几乎相同。

我可以找到的唯一类似的问题是这一个

rack-zippy和生产环境中的选项-d不提供静态资产

使用另一个Compressor，因为它看起来像Rack Zippy不工作。

解决方案

我有一个类似的问题。当我在 config / environments / production.rb 上将 config.assets.compile 设置为false时， / p>

此外，必须在部署前预先编译资产。

I followed this tutorial on how to compress assets in Heroku.

http://www.cheynewallace.com/serving-compressed-assets-with-heroku-rack-zippy/

Here is my Application.rb file

require File.expand_path('../boot', __FILE__)

require 'rails/all'

Bundler.require(*Rails.groups)

module Blog
  class Application < Rails::Application

    config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
    config.exceptions_app = self.routes

    config.cache_store = :memory_store
    Rails.application.config.middleware.swap(ActionDispatch::Static, 
    Rack::Zippy::AssetServer, Rails.public_path)

  end
end

My Gem File

gem 'yui-compressor', '~> 0.12.0'
gem 'rack-zippy'

I ran heroku run rake middleware and got eh following output

use Rack::Sendfile
use Rack::Zippy:AssetServer

Now when I go to Developer Tools and the Network Tab, I see that the size is nearly identical to the content for every asset. Which means the assets were not compressed.

The only similar question I could find was this one

rack-zippy and option -d in production env doesn't serve static assets

And the answer didn't work.

Should I use another Compressor, because it looks like Rack Zippy does not work.

解决方案

I had a similar problem. Things started to work when I set config.assets.compile to false on config/environments/production.rb.

In addition is necessary pre-compile the assets before deploy.
