Basically, exactly as the title says. I have a gem installed that gives me some JS to use. This wasn't a problem before as I was using Sprockets + Assets pipeline.
Now, I migrated to jsbundling-rails and have literally no idea how to include that JS code provided by gem. I've spent like 10 hours searching and no luck so far.
Please, help me.
The gem would have to have a js package that can be installed with yarn/npm so that it can be imported in application.js. If it doesn't, you can setup a js file to be processed only by sprockets, like in the old days.
Add another javascript entry point that will skip esbuild and will be processed only by sprockets.
Update manifest:
// app/assets/config/manifest.js
//= link custom.js
Add //= require directive:
// app/assets/javascripts/custom.js
//= require gem_javascript
Add it to layout:
<!-- app/views/layouts/application.html.erb -->
<%= javascript_include_tag "application", "custom", "data-turbo-track": "reload", defer: true %>
Alternatively, instead of using //= require add gem_javascript to javascript_include_tag:
<%= javascript_include_tag "application", "gem_javascript", "data-turbo-track": "reload", defer: true %>
Might have to add it to manifest as well for precompilation:
// app/assets/config/manifest.js
//= link gem_javascript
