JSON Schema to Mongoose Schema

This package was inspired by convert-json-schema-to-mongoose, but it's a bit more flexible and addresses the following:

• ability to parse JSON schemas that are greater than JSON-Schema draft-04
• parses sub-schemas into their own nested Schema instances to avoid required properties in them to cause false validation errors on their optional parents
• ability to parse "anyOf" properties*
• fully type-safe
• thoroughly tested

*as long as all alternatives are of "type": "object" and properties with the same name have the same value types across alternatives

There are examples of highly complex valid schemas within the fixtures directory.

IMPORTANT: $ref is currently not supported.

We use this project along typescript-json-schema to have our Typescript interfaces be the single source of truth that generate the JSON schema that we then translate to Mongoose schema for each entity within our apps.
