can't prevent scripts from loading when they generated with append_javascript_pack_tag

[benjamindickens]

Desired behavior:

i want method "append_javascript_pack_tag" to be able to change src attribute to data-src in script tag or add another method to get list with urls of all generated chunks and be able to pass as string to some custome data-attr.

Actual behavior:

right know i really need to delay loading of all scripts(not executing) on my page and i am not able to. i have been searching a method to help me parse this data some how from this method append_javascript_pack_tag to get src of each generated script and add it myself with some inline js after some event; please help me somehow (( may be there is some another way to complete the task

Setup environment:

• Ruby version: ruby-3.2.0
• Rails version:
• Shakapacker version:

Converted it from issue info discussion as that feels more sensible.

append_javascript_pack_tag only adds files to render queue, it's the javascript_pack_tag declaration that loads them in as script tags.

Your best bet is probably monkey patching the methods. I think javascript_pack_tag_queue

shakapacker/lib/shakapacker/helper.rb

Line 105 in 49e4b2c

non_deferred = sources_from_manifest_entrypoints(javascript_pack_tag_queue[:non_deferred], type: :javascript)

would give you the list of sources that you can then pass to any custom handling
