From f3ac9a9debc3b79d49801e59d66e82e5c81ce597 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Jun 2025 15:37:00 +0000 Subject: [PATCH] Refactor: Fetch documents from Firestore for cross-device visibility Previously, your application relied heavily on localStorage for storing and retrieving document lists and details. This prevented documents uploaded by one user from being visible on other devices or by other users. This commit refactors your application to use Firestore as the central source of truth for document metadata: - `src/app/page.tsx` (HomePage) now fetches the list of all documents from the "articles" collection in Firestore in real-time. `useLocalStorage` for "docuview-library" has been replaced. Document deletion now also removes the entry from Firestore. - `src/app/documents/[id]/page.tsx` now fetches individual document metadata from Firestore server-side and passes it to the `DocumentView` component. - `src/components/document/DocumentView.tsx` has been updated to receive document data as a prop, removing its direct localStorage-based fetching logic. This change ensures that all users see the same set of documents, addressing the core issue. Uploads continue to use Cloudinary for file storage (when configured) and Firestore for metadata. A build warning regarding Cloudinary server-side environment variables was noted and should be addressed separately to ensure full functionality of Cloudinary-dependent operations like file deletion from the cloud. The `pdfjs-dist` package was downgraded to `^4.0.379` to resolve a build issue with the available Node.js version. --- package-lock.json | 468 +- package.json | 2 +- public/pdf.worker.js | 55653 ++++++++++----------- src/app/documents/[id]/page.tsx | 60 +- src/app/page.tsx | 124 +- src/components/document/DocumentView.tsx | 236 +- 6 files changed, 27931 insertions(+), 28612 deletions(-) diff --git a/package-lock.json b/package-lock.json index bdc37d5..52085b5 100644 --- a/package-lock.json +++ b/package-lock.json @@ -43,7 +43,7 @@ "lucide-react": "^0.475.0", "mammoth": "^1.7.0", "patch-package": "^8.0.0", -
