Configure GraphQL Data Source

The GraphQL data source allows you to introspect GraphQL services and add them to your virtual Graph.

// wundergraph.config.ts

const countries = introspect.graphql({
  apiNamespace: 'countries',
  url: 'https://countries.trevorblades.com/',
  requestTimeoutSeconds: 10, // optional
});

configureWunderGraphApplication({
  apis: [countries],
});

First, define the url which will be used to introspect the GraphQL service. Next, add an optional namespace to put the GraphQL schema in a specific namespace.

Aside from the url, you can also define a headers configuration, you can configure mTLS, or set a different URL for subscriptions by setting subscriptionsURL.

Refer to the configure introspection for protected API guide.
