/**
|
|
* When a document's slug changes, appends the OLD slug to a `slugHistory` array
|
|
* field. The project reads slugHistory to serve a 301 redirect from old URLs to
|
|
* the current one — so changing a slug doesn't 404 the old address (a real SEO
|
|
* loss / audit finding).
|
|
*
|
|
* Requires a `slugHistory` field on the collection:
|
|
* { name: 'slugHistory', type: 'array', fields: [{ name: 'slug', type: 'text' }],
|
|
* admin: { readOnly: true } }
|
|
*
|
|
* hooks: { beforeChange: [trackSlugHistoryHook] }
|
|
*
|
|
* The project then, in resolveRoute or a redirect check, looks up slugHistory and
|
|
* 301s to the current slug. See docs/hooks.md.
