Instance Method Details

#asset_pack_path(name, **options) ⇒ Object

Computes the full path for a given webpacker asset. Return relative path using manifest.json and passes it to asset_url helper This will use asset_path internally, so most of their behaviors will be the same. Examples:

In development mode:

<%= asset_pack_path 'calendar.js' %> # => "/packs/calendar.js"

In production mode:

<%= asset_pack_path 'calendar.css' %> # => "/packs/calendar-1016838bab065ae1e122.css"

end

#javascript_pack_tag(name, **options) ⇒ Object

Creates a script tag that references the named pack file, as compiled by Webpack per the entries list in config/webpack/shared.js. By default, this list is auto-generated to match everything in app/javascript/packs/*.js. In production mode, the digested reference is automatically looked up.

Examples:

# In development mode:
<%= javascript_pack_tag 'calendar', 'data-turbolinks-track': 'reload' %> # =>
<script src="/packs/calendar.js" data-turbolinks-track="reload"></script>

# In production mode:
<%= javascript_pack_tag 'calendar', 'data-turbolinks-track': 'reload' %> # =>
<script src="/packs/calendar-1016838bab065ae1e314.js" data-turbolinks-track="reload"></script>
