There are several ways to generate code and schema based on a JSON data blob when building an API. One way is to use a tool like NJsonSchema which can generate a schema from a type. Another way is to use JSON Schema which is a contract for your JSON document that defines the expected data types and format of each field in the response. You can also use Visual Studio Marketplace which allows you to easily generate a schema file from a JSON file and generate a JSON file with dummy data based on a schema file. I hope this helps. Let me know if you have any other questions.

Unfortunately, there is no direct way to generate all the necessary Mongoose schemas and APIs from a JSON data blob. However, there are some third-party tools available that can help simplify the process. One such tool is "mongoose-gen", which can generate Mongoose schemas and models from JSON schema files. Another tool is "json-schema-to-mongoose", which can convert JSON schema files to Mongoose schemas. It's important to note that while these tools can be useful, they may not always generate the most efficient or optimized code. It's always a good practice to review the generated code and make any necessary adjustments before using it in a production environment.
