How to import a link from database to Sanity project?

The easiest and quickest way to import data into your Sanity project depends on what you're importing, but here are your main options:

Quickest: Using the Sanity CLI (Recommended)

If you have data in NDJSON format (newline-delimited JSON), the CLI import command is your fastest route:

sanity dataset import <file> <targetDataset>

For example:

sanity dataset import my-data.ndjson production

Key things to know:

• Each line in your NDJSON file should be a complete JSON document
• Documents need a _type field (and optionally an _id)
• For images/files, use the special _sanityAsset property: "image@file:///path/to/image.jpg" or "image@https://example.com/image.jpg"
• You can import .ndjson files or .tar.gz archives (which include assets)

Useful flags:

• --replace - Overwrites existing documents with the same _id
• --missing - Only creates documents that don't exist yet
• --allow-failing-assets - Continues import even if some assets fail

Run sanity dataset import --help to see all options.

Alternative: Using a Client Library

If you need more control or are importing from a custom source, you can use the Sanity JavaScript client with methods like client.create() or client.createOrReplace().

Important considerations when using the client:

• Implement rate limiting (max 25 requests/second)
• Use transactions for multiple mutations
• Set visibility mode to deferred for large imports
• Upload assets first, then reference them in documents

For a single link/document, you could also just create it directly in Sanity Studio if it's a one-off!

What type of data are you looking to import? That'll help determine the best approach.
