Important note: Microsoft provides its own emulator for Asure CosmosDB NoSQL, you can find more information on this page:

https://learn.microsoft.com/en-us/azure/cosmos-db/how-to-develop-emulator?pivots=api-nosql&tabs=docker-linux%2Cjavascript

You should consider using this one as it is fully supported by Microsoft.

This emulator is created as a replacement for azure-cosmos-emulator on NoSQL to work around three issues:

1. The evaluation period mode.
2. The (undocumented) capability to store data.
3. The unstable image that requires restart from time-to-time.

Current restrictions for the project:

1. Works only with collections having a id property that is as well the partition of the collection.
2. Don't support attachments
