Store Proposal Context Files and Media in Vercel Blob Storage #70
Description
✨ Objective
To efficiently manage large files such as PDFs, Word documents, and images associated with proposals, we need to integrate Vercel’s Blob Storage system. This will allow the platform to offload large and binary files from our server or database, improving performance, scalability, and delivery time for proposal context files.
🛠 Tasks
🔧 Backend
Integrate Vercel Blob SDK into the backend:
Install the Vercel Blob SDK.
Configure access credentials using environment variables (VERCEL_BLOB_READ_WRITE_TOKEN, etc.).
Create utility functions to:
Upload files to the blob.
Retrieve blob URLs.
Delete blobs when needed (e.g., when a proposal is removed or updated).
Modify Proposal File Upload Logic:
Update the existing proposal creation API to:
Accept file uploads (.pdf, .docx, images).
Store those files in Vercel Blob Storage.
✅ Acceptance Criteria
Proposal-related files (context documents and media) are uploaded and stored in Vercel Blob.
Blob URLs are stored in the database and accessible in the proposal UI.
Old file handling logic (local storage) is removed or deprecated.
Uploaded files are reliably accessible and fast to load/download.
