mongodbHow to work with JSON data in MongoDB?

MongoDB provides a native JSON data type that allows developers to store and query JSON documents directly in the database. To work with JSON data in MongoDB, you can use the $jsonSchema operator to validate the structure of the documents. Additionally, you can use the $jsonArray operator to query for specific elements in an array.

Example code

db.collection.find({
  $jsonSchema: {
    bsonType: "object",
    required: ["name", "age"],
    properties: {
      name: {
        bsonType: "string",
        description: "must be a string and is required"
      },
      age: {
        bsonType: "int",
        minimum: 0,
        description: "must be an integer and is required"
      }
    }
  }
})

Output example

{ "_id" : ObjectId("5f3f9f9f9f9f9f9f9f9f9f9f"), "name" : "John", "age" : 30 }
