如何在Heroku上加速咖啡脚本资产的编译

Question

3.2和大量小型咖啡脚本文件一起部署需要大量时间：

有没有办法加快Heroku上的资产编译？

Answer 1

选项1:在本地预编译资产

您可以在本地编译您的资产，将它们添加到源代码管理中，并将它们推送到Heroku：

RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets
git commit -m "Precompile assets"

Heroku随后将检测预编译资产并跳过编译。

-----> Preparing Rails asset pipeline
       Detected manifest.yml, assuming assets were compiled locally

选项2:使用模缓存缓存链轮

通过http://blog.alexmaccaw.com/faster-deploys (免责声明:我还没有尝试过这种方法)。

启用memcache附加项。

heroku addons:add memcachier

将dalli和memcachier添加到Gemfile中。

在config/environments/production.rb中配置资产缓存存储

config.assets.cache_store = :dalli_store
