Sometimes, we want to use Mongoose without defining a schema.

In this article, we’ll look at how to use Mongoose without defining a schema.

### How to use Mongoose without defining a schema?

To use Mongoose without defining a schema, we can define a field with the `Mixed` data type.

For instance, we write

``````const Any = new Schema({ any: {} });
``````

or

``````const Any = new Schema({ any: Schema.Types.Mixed });
``````

to define the `Any` schema that has the `any` property set to the mixed type by setting the `any` property to `{}` or `Schema.Types.Mixed`.

As a result, we can set any value as the value of `any`.

### Conclusion

To use Mongoose without defining a schema, we can define a field with the `Mixed` data type.
