WunderGraph has partnered with MongoDB Atlas to provide a new data source type, allowing users to easily build GraphQL APIs from their MongoDB databases without manual work. This integration enables the creation of secure, production-ready GraphQL APIs with authentication and authorization out of the box. WunderGraph's features include injecting claims into queries for authentication and authorization, live queries that automatically update user interfaces, and an easy configuration process using introspection. The partnership aims to help users build the next generation of API and microservices infrastructure, particularly in real-time applications such as chats.
