From 2fc310a2f20e59ab9dd5a4f7925d33190ff8a3a6 Mon Sep 17 00:00:00 2001 From: Corentin Date: Fri, 8 May 2026 00:51:02 +0200 Subject: [PATCH] feat(acadenice): add bidirectional backlinks + wikilinks for R3.2 - Migration: acadenice_backlink table (source/target/link_type/excerpt/workspace) with 3 indexes and UNIQUE(source,target,type) constraint. Up+down. - Backend module AcadeniceBacklinksModule: BacklinkParserService: walks Tiptap JSON, extracts wikilinks/mentions/databaseView. BacklinkIndexerService: idempotent delete-then-insert per page save. BacklinkService: permission-aware query (space_members / public visibility). BacklinksController: GET /api/acadenice/pages/:pageId/backlinks (JWT auth). PageContentUpdatedListener: OnEvent handler for collab saves -> async reindex. Tests: 16 Vitest specs (parser/indexer/service/controller). - PersistenceExtension patch: emits ACADENICE_PAGE_CONTENT_UPDATED_EVENT after each collab onStoreDocument (fire-and-forget, no impact on save path). - CoreModule patch: imports AcadeniceBacklinksModule. - Frontend WikilinkExtension: Tiptap inline atom node, [[Title]] / [[Title|alias]], Suggestion popup (reuses mention pattern + floating-ui), ReactNodeView with broken-link state, insertWikilink command. Tests: 9 Vitest specs (schema/attrs/commands/HTML parse+render). - LinkedReferencesPanel: React Query useBacklinks(pageId, staleTime=30s), accordion grouped by link_type, excerpt preview, navigate to source page. Tests: 7 Vitest specs (loading/error/empty/render/navigate/groups). - extensions.ts patch: + WikilinkExtension in mainExtensions[]. - full-editor.tsx patch: + LinkedReferencesPanel below editor (Divider + panel). - i18n: 11 keys added in en-US and fr-FR (backlinks.* + wikilink.*).
