I'm upgrading a Rails 5 app to Rails 6, so in Rails 5 before webpacker was the default, I had a js file that I was loading separately from the application.js like this:
In config/initializers/assets.rb
Rails.application.config.assets.precompile += %w(magic.js)
and in my views I was using it like this:
<%= asset_url('magic.js'); %>
Now as Rails 6 uses webpack, I am adding the magic.js file to app/javascript/packs (which makes it as an entry file) and will produce a separate magic.js output in plus of the application.js, however I can't find any helper to access the URL, i.e: packs_url (equivalent to asset_url)
Does anyone have an idea?
You are currently using webpacker. So, You can use javascript_pack_tag to render javascript pack files.
Here is an example:
<%= javascript_pack_tag 'magic' %>
For getting the url:
<%= asset_pack_path 'magic.js' %>
