Frequently Asked Questions

How does GraphQL map to MongoDB?

In GraphQL, root query fields correspond to MongoDB collections, field selections correspond to projections, arguments correspond to filter conditions, and nested fields correspond to queries on related collections.

Does it support sorting and pagination?

Yes. orderBy arguments become .sort(), limit/first become .limit(), and offset/skip become .skip().

Does it handle nested relations?

Yes. Since MongoDB doesn't natively join collections like GraphQL resolvers do, nested fields are converted to separate find() queries on related collections.

Is this converter free?

Completely free, no limits. Also try: MongoDB to GraphQL, GraphQL to SQL, GraphQL to REST, GraphQL Formatter.
