Frequently Asked Questions

What is a Mongoose Schema?

A Mongoose Schema defines the structure of documents in MongoDB collections. It specifies the fields, their types, validation rules, and other properties that determine how data is stored and retrieved.

How accurate is the type inference?

The converter accurately identifies common JavaScript types and maps them to appropriate Mongoose Schema types. It can detect strings, numbers, booleans, dates, arrays, and nested objects. For complex or ambiguous types, it defaults to Mixed type for maximum flexibility.

What are timestamps?

When enabled, timestamps automatically add createdAt and updatedAt fields to your documents. These fields are managed by Mongoose and help track when documents are created and modified.

What is strict mode?

Strict mode ensures that only fields defined in the schema will be saved to the database. Any additional fields in the documents will be automatically removed. This helps maintain data consistency.
