AWS S3 Digital Asset Management (DAM) plugin for Sanity.io

Allows uploading, referencing and deleting video and audio files to S3 directly from your Sanity studio. Is a flavor of sanity-plugin-external-dam.

Installing

Start by installing the plugin:

sanity install s3-dam

The rest of the work must be done inside AWS' console:

• Create a public S3 bucket (or use an existing one)
• Configure CORS for your bucket to accept the origins your studio will be hosted in (including localhost)
  • Refer to S3's guide on CORS if this is new to you (it was for me too!)
  • You can use the template at s3Cors.example.json
• Create Lambda functions for creating the pre-signed URLs we'll use to post objects to S3 and deleting objects
  • Use the templates at getSignedUrl.example.js and deleteObject.example.js
  • Set the necessary permissions for execution role of each function:
    • getSignedUrl: "Write->PutObject" and "Permissions Management->PutObjectAcl"
    • deleteObject: "Write->DeleteObject"
  • Make these functions available through HTTP requests by adding API Gateway triggers
    • Ensure these gateways have CORS enabled for the origins you'll use
    • I strongly recommend using the same gateway for both functions for simplicity of configuration

With these in hand, fill-in the plugin's configuration form where you'll fill in the bucket key (ex: my-sanity-bucket), the bucket region (ex: ap-south-1), the URL for both Lambda functions and an optional secret for validating input in functions.

I plan on recording a video tutorial going through the process in detail. Until then, reach out if you have questions 😉

Using

Use the s3-dam.media type in your fields. Examples:

{
    name: "video",
    title: "Video (S3)",
    type: "s3-dam.media",
    options: {
        accept: "video/*",
        storeOriginalFilename: true,
    },
},
{
    name: "anyFile",
    title: "File (S3)",
    type: "s3-dam.media",
    options: {
        // Accept ANY file
        accept: "*",
        storeOriginalFilename: true,
    },
},
