# Lets expand on this into a dev plan and for starters we are going to use a shared server, with c-panel and node.js app install capabilities, also has database capabilities and domain and dns management:

U — File \& Asset Manager: Build a media library with S3/R2 storage backend. Clients upload images, documents, and brand assets that are reusable across their page builder and dashboards

Build Phase U as a **tenant-scoped media library** in your existing Node app, storing metadata in your DB and files in an S3-compatible bucket (AWS S3 or Cloudflare R2) using the standard S3 API.[^1][^2][^3]

***

## 1. Storage and multi-tenant model

- Use a single bucket with **tenant-prefixed keys**, e.g. `tenant-{id}/images/...`, `tenant-{id}/docs/...`, as shown in multi-tenant S3 examples.[^4][^5]
- Configure S3/R2 client in Node with env vars in cPanel:
    - `S3_ENDPOINT` (R2 endpoint if using R2).[^6][^7][^2][^3]
    - `S3_BUCKET`, `S3_ACCESS_KEY`, `S3_SECRET_KEY`.
- Restrict access through your backend (no public write), optionally use presigned URLs for direct uploads later.[^8][^9]

DB tables:

- `assets`
    - `id`
    - `tenant_id`
    - `file_name`
    - `mime_type`
    - `size_bytes`
    - `storage_key` (e.g. `tenant-123/images/logo.png`)
    - `kind` (`image`, `document`, `video`, `other`)
    - `tags` (JSON / text)
    - `created_by_user_id`
    - timestamps
- `asset_links` (to reuse across modules)
    - `id`
    - `asset_id`
    - `linked_type` (`page_block`, `dashboard_widget`, `crm_contact`, etc.)
    - `linked_id`

This keeps file metadata tenant-scoped and linkable from the page builder and dashboards.[^10][^11]

***

## 2. Backend upload/download APIs (Node on cPanel)

Use Express + Multer or busboy to accept multipart uploads and forward them to S3/R2 via the Node S3 SDK.[^12][^13][^14][^1][^8]

Endpoints:

- `POST /api/assets`
    - Authenticated, tenant-scoped.
    - Accepts file upload, figure out `mime_type`, generate a unique key:
        - `const key = \`${tenantId}/${folder}/${uuid()}-${originalName}\`;`
    - Upload to S3/R2 via `PutObject` / `upload`:
        - Standard pattern: `S3.upload({ Bucket, Key, Body, ContentType })`.[^14][^1][^12]
    - Store metadata in `assets` and return asset record (with URL or path).
- `GET /api/assets`
    - List/filter/search by `kind`, `tags`, `file_name`, pagination.
- `GET /api/assets/:id`
    - Return metadata + a signed or proxied URL for use in frontend.
- (Optional) `DELETE /api/assets/:id`
    - Soft-delete metadata, and optionally delete from S3/R2.

S3-compatible Node examples show exactly this pattern: accept file → send to S3→ store key in DB.[^5][^1][^12][^8]

***

## 3. Media library UI in the app

Add a **“Media Library” / “Assets”** section under settings, and embed pickers into builder/dashboards:

- Library view:
    - Grid or list of assets with thumbnails (for images) and icons for docs.
    - Filters: type (image/doc), tag, upload date.
    - Actions: upload new, rename, tag, delete (soft).
- Asset picker modal:
    - In **page builder** (Phase H): image blocks can open the media picker to select an existing asset or upload a new one.
    - In **dashboard widgets**: allow selecting brand logos or illustrative images from the library.

This makes assets reusable across pages and dashboards, which is the core requirement for a media library.[^11][^10]

***

## 4. S3/R2 configuration for shared hosting

- For **Cloudflare R2**:
    - Use its S3-compatible API: set endpoint like `https://<id>.r2.cloudflarestorage.com`, plus access key and secret.[^7][^2][^3][^6]
    - Use standard AWS SDK `S3` client with that endpoint and your bucket.[^1][^12][^14]
- For **AWS S3**:
    - Use region, bucket, and credentials with the AWS SDK as usual.[^12][^8][^1]

On your cPanel Node app, keep keys in env vars, not code.

***

## 5. Integration with other modules

- **Page builder**:
    - Replace free-text image URLs with `asset_id` references; the renderer resolves to S3/R2 URLs.
- **Dashboard \& CRM**:
    - Allow attaching assets to CRM contacts, deals, or project tasks via `asset_links`.

This keeps brand assets centralized and consistent across AIISTECH.

***

## 6. Milestones

1. **U1 – Storage \& API**
    - Configure S3/R2 client.
    - Implement `assets` table and `POST/GET` endpoints (upload + list).
2. **U2 – Media library UI**
    - Media library view in dashboard.
    - Basic upload and selection UX.
3. **U3 – Builder \& dashboard integration**
    - Image/file pickers in page builder blocks and relevant dashboard components.
4. **U4 – Polishing \& governance**
    - Quotas per tenant, basic type/size validation, tagging, and soft delete.

Do you plan to start with Cloudflare R2 or AWS S3 for the first version of the asset storage backend?
