from map (bson.M) instead of struct?

[amills-vibeirl]

this library seems to work fine with structs, but what about maps like bson.M{}?

For example, this code:

package main

import (
	"encoding/json"
	"fmt"
	"github.com/invopop/jsonschema"
	"go.mongodb.org/mongo-driver/bson"
)

// Define your struct here. This should mirror your JSON data.

type MyData struct {
	Name    string `json:"name"`
	Age     int    `json:"age"`
	Address string `json:"address,omitempty"`
}

func main() {
	// Generate a JSON schema for your struct

	{

		schema := jsonschema.Reflect(&MyData{})

		// Marshal the schema into JSON
		schemaJSON, err := json.MarshalIndent(schema, "", "  ")
		if err != nil {
			panic(err)
		}

		// Print the JSON schema
		fmt.Println(string(schemaJSON))
	}

	{
		var MyData = bson.M{
			"this_is_string": "value",
			"this_is_int":    5,
			"this_is_struct": &MyData{
				Name:    "<name?",
				Age:     0,
				Address: "<address>",
			},
		}
		schema := jsonschema.Reflect(&MyData)

		// Marshal the schema into JSON
		schemaJSON, err := json.MarshalIndent(schema, "", "  ")
		if err != nil {
			panic(err)
		}

		// Print the JSON schema
		fmt.Println(string(schemaJSON))
	}
}

yields this output:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "$ref": "#/$defs/MyData",
  "$defs": {
    "MyData": {
      "properties": {
        "name": {
          "type": "string"
        },
        "age": {
          "type": "integer"
        },
        "address": {
          "type": "string"
        }
      },
      "additionalProperties": false,
      "type": "object",
      "required": [
        "name",
        "age"
      ]
    }
  }
}
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "$id": "https://go.mongodb.org/mongo-driver/bson/primitive/m",
  "$ref": "#/$defs/M",
  "$defs": {
    "M": {
      "type": "object"
    }
  }
}

this schema def is not really correct (or useful at least):

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "$id": "https://go.mongodb.org/mongo-driver/bson/primitive/m",
  "$ref": "#/$defs/M",
  "$defs": {
    "M": {
      "type": "object"
    }
  }
}
