Is there any way to speed up asset compilation on Heroku?

有没有办法加速Heroku上的资产编译?

Option 1: Precompile assets locally

选项1:在本地预编译资产

You can compile your assets locally, add them to source control and push them to Heroku:

您可以在本地编译资源,将它们添加到源代码管理并将它们推送到Heroku:

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

Heroku will then detect the precompiled assets and skip compilation

然后Heroku将检测预编译的资产并跳过编译

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

See https://devcenter.heroku.com/articles/rails-asset-pipeline#the-rails-3-asset-pipeline for additional info

Option 2: Use memcache caching for sprockets

选项2:对链轮使用memcache缓存

Enable a memcache add-on

启用内存缓存加载项

heroku addons:add memcachier

Add dalli and memcachier to your Gemfile.

将dalli和memcachier添加到您的Gemfile中。

Configure asset cache store in config/environments/production.rb

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

config.assets.cache_store = :dalli_store
