Export and apply Mongo Schema

In this page you will learn how to export the model you have designed as a Mongo Schema and apply it in your MongoDB instance.

• The model that will be used for this guide will contain a single collection, User.

  

• In order to export the Mongo Schema, click 'Export' button in the toolbar. The modal shown below will prompt, where you have to select 'Mongo Schema' option.

  

• In this case, the content of the generated file will this. Please copy the content to your clipboard.

  db.createCollection("User", {
    validator: {
      $jsonSchema: {
        bsonType: "object",
        title: "User",
        required: ["_id", "name", "address"],
        properties: {
          "_id": { bsonType: "objectId" },
      "name": { bsonType: "object", title: "name", properties: { "firstName": { bsonType: "string" }, "lastName": { bsonType: "string" }, }, },
      "address": { bsonType: "string" },
      "emails": { bsonType: "array", items: { bsonType: "string" } },
        },
      },
    },
  });

• Now, let's go to our MongoDB instance. Open MongoDB shell, mongosh, create a new database, paste the contents of your clipboard and press enter. After this, the model designed will be created in the database.

  

• In MongoDB Compass we can check the new collection and its schema.

  

• Let's create a new document. If the document fails the validation, it will not be created.

  

• If the document follows the designed schema, it will be created
