Azure Functions shopping list API using Cosmos DB.

An example of using Cosmos DB and Azure Functions to create a serverless shopping list API.

Functions are using the HTTP trigger. The functions are the following.

• GetShoppingCartItems
• GetShoppingCartItemById
• CreateShoppingCartItem
• PutShoppingCartItem
• DeleteShoppingCartItem

The functions are written in C# for this example.

The application needs an environment variable generated called connectionString.

• This environment variable should be the access key connection strings provided by your CosmosDB resource.
• This should be stored in Azure Key Vault and referenced within the application settings.
