File-based Operations

File-based Operations is a pattern we've adopted from NextJS. There are many ways to define the Operations of an API. We've decided to choose a simple approach that developers are familiar with.

The rules are simple:

• Operations must be defined in the folder .wundergraph/operations
• Each .graphql file becomes an API endpoint.
• Each file should contain exactly one GraphQL Query, Mutation or Subscription.
• Operations can be annotated with @directives to adjust their behaviour.
• The file name in front of .graphql defines the name of the Operation: NewPost.graphql becomes the NewPost Operation

That's it, a simple set of constraints that lets you build API Endpoints by writing GraphQL Operations. If you're interested, read more on how we create the API Endpoints.
