Research direction

Read the referenced module issues cwa-nuxt-module#157, #408, and #259, along with api-components-bundle#502 and docs#259 for the cycle restriction. Update the documentation for cloning, multi-location deletion, and the route cache default, including the 200-route limit, unbounded setting, and memory tradeoff. Done when the documented behavior matches these changes and the relevant existing docs are updated.

Description

documentation

Module changes for the next @cwa/nuxt release (after 2.0.0-alpha.21) that need documenting:

Clone a component (cwa-nuxt-module#157, #408)

  • What clone is: the same component, with the same IRI, placed in another position. It is never a copy, so an edit in one place, or publishing it, changes it everywhere.
  • The flow:
    1. Select a component and choose Clone in the manager bar's dots menu.
    2. Clone mode shows a "Cloning" bar with Cancel; Escape also cancels. The header's Enable Navigation toggle lets you browse the site while in clone mode.
    3. Clicking a target opens a dialog offering what adding a component offers there: Add before or after, Add to start or end, Add here in an empty group, or Use here in a page-data slot. Options that aren't allowed are disabled, with every reason.
    4. A target in the layout is flagged as appearing on every page that uses it.
  • Several instances: every on-screen instance of a selected component is outlined, and every instance of the component being cloned is highlighted.
  • Delete: a component used in several locations asks Delete from all X locations or Remove from this location only. The Info tab shows "Used in X locations".
  • Cycles: a container can't be placed inside its own subtree. The module disables the option, and the API refuses it (api-components-bundle#502, docs#259).

Route cache default (cwa-nuxt-module#259)

  • cwa.routeCacheLimit now defaults to 200 routes, not 50. Lookups and eviction no longer slow down as the store grows; navigation stays at about 5 ms up to 100k stored resources.
  • Set 0 for unbounded, which is only sensible for small sites.
  • Memory, not speed, is the limit: about 3 KB per stored resource, so roughly 100 MB at ~30k resources. An IndexedDB cold tier is tracked in cwa-nuxt-module#405 for sites that would exceed that.
