Class: Seo::LegacyUrlMigrator

Inherits:
BaseService show all
Defined in:
app/services/seo/legacy_url_migrator.rb

Overview

Rewrites legacy product and support URLs in HTML content to canonical
hierarchical paths.

Legacy patterns handled:
/products/code/:sku[/reviews|/faqs] -> /:canonical_path[/reviews|/faqs]
/products/line/:url[/reviews|/faqs] -> /:canonical_path[/reviews|/faqs]
/support/sku/:sku -> /:canonical_path/support
/support/:main_pl/:sub_pl -> /:canonical_path/support
/support/:main_pl -> /:canonical_path/support

Links may be absolute (https://www.warmlyyours.com/{locale}/...)
or relative (/{locale}/...). The rewrite preserves whichever form
was used and keeps the locale prefix intact.

Usage:
result = Seo::LegacyUrlMigrator.new.process(html_string)
result.html_out # rewritten HTML
result.links_migrated # [{ from: old_href, to: new_href }, ...]
result.skipped # [{ href: ..., reason: ... }, ...]
