Module: SwalRails::AssetManifest

Defined in:
lib/swal_rails/asset_manifest.rb

Overview

Computes the list of vendored sweetalert2 assets the host should precompile, based on ‘SwalRails.configuration.assets_mode` and `precompile_strategy`. Kept side-effect-free so it’s easy to test without booting a full Rails app.

.precompile_for(configuration, app_root: nil) ⇒ Object

Returns the list of asset paths to add to ‘config.assets.precompile`. Always includes the gem’s own JS/CSS entrypoints (small, host-facing). Vendored sweetalert2 variants depend on ‘precompile_strategy`:

`:all`     → every JS + CSS variant + every theme (legacy)
`:minimal` → only the variant matching the resolved assets_mode,
             plus the canonical CSS bundle

def self.precompile_for(configuration, app_root: nil)
  strategy = configuration.precompile_strategy
  mode = resolve_assets_mode(configuration.assets_mode, app_root)

  base = GEM_FILES.dup
  base.concat(vendor_files_for(strategy, mode))
  base.concat(THEME_FILES) if strategy == :all
  base.uniq
end

.resolve_assets_mode(mode, app_root) ⇒ Object

When ‘assets_mode` is `:auto`, sniff the host’s filesystem to infer which Rails asset pipeline is in use. Mirrors the heuristic in the install generator (importmap.rb → :importmap, package.json → :jsbundling, else :sprockets) so explicit and auto-detected behaviour match.
