If you've ever worked with Azure Cosmos DB directly, you know the pain. Writing raw SQL queries by hand, managing parameterized inputs, zero validation before data hits the database. Compare these two approaches for finding electronics under $100:

Raw @azure/cosmos SDK:

const { resources } = await container . items . query ({ query : ' SELECT * FROM c WHERE c.category = @cat AND c.price >= @min AND c.price <= @max ' , parameters : [ { name : ' @cat ' , value : ' electronics ' }, { name : ' @min ' , value : 10 }, { name : ' @max ' , value : 100 }, ], }) . fetchAll ();

const products = await Product . find ({ category : ' electronics ' , price : { $gte : 10 , $lte : 100 }, });

Cosmoose is a type-safe ODM for Azure Cosmos DB, built with TypeScript.…
