The developers of MongoDB have announced that you can now use GraphQL in JavaScript applications to interact with MongoDB documents. The facility has been added through Stitch integration in MongoDB Atlas clusters.
MongoDB is a NoSQL document database that stores its documents in a JSON-like format with schema. GraphQL is a query language for APIs originally developed for internal use in Facebook before being made open source.
GraphQL means you can create a query that works on and returns only the fields you want from an API, similar to a MongoDB projection or a SQL query. This is much simpler than making an HTTP request to an API endpoint and receiving the full payload of that resource as a response.
Until now if you wanted to use GraphQL in a JavaScript app on MongoDB data, you'd need a dedicated web service with contained schema information, resolve functions with database logic, and other middleware logic to sit between the database and the client facing application.By making use of Stitch for authentication and GraphQL queries makes things much easier. MongoDB Stitch is a serverless platform that handles server interactions. It is built on top of MongoDB Atlas, and automatically integrates the connection to your database. Developers can connect to Stitch through the Stitch Client SDKs, which are available for many platforms including JavaScript, iOS, and Android
The Stitch GraphQL API lets client apps access data stored in a linked MongoDB cluster using any standard GraphQL client. Stitch automatically creates GraphQL types for every linked collection that has a defined document schema and evaluates role-based permissions for all GraphQL requests.
