Integration of imgproxy.rb with ActiveStorage::Variant API.
Add to your project:
# Gemfile
gem "imgproxy-rails"
Given the following configuration:
# development.rb
config.active_storage.resolve_model_to_route = :rails_storage_proxy
# production.rb
config.active_storage.resolve_model_to_route = :imgproxy_active_storage
The following HTML snippet will generate different URLs in dev and prod:
# show.erb.html
<%= image_tag Current.user.avatar.variant(resize: "100x100") %>
In dev, it will generate a URL like this:
<img src="http://localhost:3000/rails/active_storage/blobs/proxy/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBBWHc9IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--0c35e9a616c29da2dfa10a385bae7172526e7961/me.png">
In prod, it will generate a URL like this:
<img src="https://imgproxy.example.com/8uVB2dYrZVOdG-1tekFjNJZ7s7VHDViXJbu9TcQavQ8/fn:me.png/aHR0cDovL2xvY2Fs/aG9zdDozMDAwL3Jh/aWxzL2FjdGl2ZV9z/dG9yYWdlL2Jsb2Jz/L3Byb3h5L2V5SmZj/bUZwYkhNaU9uc2li/V1Z6YzJGblpTSTZJ/a0pCYUhCQldIYzlJ/aXdpWlhod0lqcHVk/V3hzTENKd2RYSWlP/aUppYkc5aVgybGtJ/bjE5LS0wYzM1ZTlh/NjE2YzI5ZGEyZGZh/MTBhMzg1YmFlNzE3/MjUyNmU3OTYxL21l/LnBuZw">
You can also specify imgproxy-specific parameters in imgproxy_options attribute. Imgproxy-specific params will take precedence over ones from original API:
# height=50 and width=50 will be applied
Current.user.avatar.variant(resize: "100x100", imgproxy_options: {height: 50, width: 50})
If you are an imgproxy Pro user and you want to use it to generate previews for your videos and PDFs, just add their content types to the variable_content_types list:
config.active_storage.variable_content_types << "application/pdf"
config.active_storage.variable_content_types << "video/mp4"
config.active_storage.variable_content_types << "video/mov"
