Azure Blob Storage

File storage configuration for media assets and quote request attachments.

The platform uses Azure Blob Storage for two distinct purposes:

1. Media assets — product images and category images served via a public CDN URL.
2. Quote request attachments — files uploaded by customers when submitting a price request, stored in a SharePoint Document Library Drive.

Media assets

Media images are hosted in the webcms Azure Blob container and served from:

https://webcms.blob.core.windows.net/media

This base URL is set with NUXT_PUBLIC_MEDIA_BASE_URL and exposed to the client. The @nuxt/image module is configured to allow this domain:

// nuxt.config.ts
image: {
  provider: "ipx",
  domains: ["webcms.blob.core.windows.net"],
},

Reference images in components with the public base URL:

<NuxtImg
  :src="`${$config.public.mediaBaseUrl}/categories/gran-formato.jpg`"
  alt="Gran formato printing"
  width="800"
  height="600"
/>

Quote request attachments

When a customer submits a price request with a file, the Nitro handler uploads it to a SharePoint Document Library that is backed by a OneDrive/SharePoint Drive. The Drive is accessed through the Microsoft Graph API using the configured drive ID.

Folder structure

Each attachment is stored under:

{baseFolder}/{requestKey}/{filename}

For example:

price-requests/pr-2026-03-abc123/artwork-final.pdf

Defaults:

Setting	Default value
Library name	AssetsProducts
Base folder	price-requests
Max file size	25 MB (26,214,400 bytes)

Allowed MIME types

The following file types are accepted by default:

application/pdf
image/jpeg
image/png
image/svg+xml
application/zip
application/postscript

The allowed list is comma-separated in CRM_ATTACHMENTS_ALLOWED_MIME_TYPES and split at runtime.

File metadata stored in SharePoint

After a successful upload, the CRM price request list item is updated with:

Field	SharePoint column	Description
HasAttachment	CRM_PR_HAS_ATTACHMENT_FIELD	Boolean flag
PrimaryFileDriveItemId	CRM_PR_PRIMARY_FILE_DRIVE_ITEM_ID_FIELD	Graph Drive item ID
PrimaryFileWebUrl	CRM_PR_PRIMARY_FILE_WEB_URL_FIELD	Direct SharePoint URL
PrimaryFileName	CRM_PR_PRIMARY_FILE_NAME_FIELD	Original filename
PrimaryFileMimeType	CRM_PR_PRIMARY_FILE_MIME_TYPE_FIELD	MIME type
PrimaryFileSize	CRM_PR_PRIMARY_FILE_SIZE_FIELD	File size in bytes
