This commit adds support for GraphQL fragments with `GraphQlTester`.
Fragments allow to avoid repetition in GraphQL requests by reusing
field selection sets.
For example, the "releases" fragment can be reused in multiple queries
and make the overall document shorter:
```
query frameworkReleases {
project(slug: "spring-framework") {
name
...releases
}
}
query graphqlReleases {
project(slug: "spring-graphql") {
name
...releases
}
}
fragment releases on Project {
releases {
version
}
}
```
With this change, `GraphQlTester` accepts fragments as `String` or can
load them by their name using the configured `DocumentSource`, similarly
to the document support.
Closes gh-964
This commit adds two new methods on the `WebSocketGraphQlTester` builder
to configure `GraphQlClientInterceptor` instances on the client.
For now, this is only accessible on the WebSocket tester but could be
promoted to a higher level builder in the future.
Closes gh-823
Prior to this commit, the WebFlux and WebMVC infrastructure would only
support subscriptions over the WebSocket and RSocket transports.
This commit adds the `GraphQlSseHandler` implementations for both web
frameworks. This handler will send GraphQL responses as as stream of
Server-Sent Events, over an HTTP response with the "text/event-stream"
content type.
This implementation only supports the "Distinct connections mode" and
will reject all operations other than Subscriptions.
This commit also enhances the `HttpGraphQlTransport` client transport to
support subscriptions over this new protocol.
Closes gh-309
This commit adds reachability metadata for resources loaded by the
`GraphQlClient` and `GraphQlTester` when using the `document("name")`
API variant. This method loads the query file from the classpath at
particular locations, namely `"classpath:graphql-documents/"` and
`"classpath:graphql-test/"` with the `".graphql"` and `".gql"` file
extensions.
This commit adds the relevant resource metadata so that such resources
are loaded in the GraalVM native image at build time when the client or
the tester are reachable through the static analysis.
Fixes gh-575
As of #108, the `"application/graphql+json"` media type is supported and
has been made the default.
It seems that it is not ready for adoption now; so while we'll keep
supporting it, this commit reverts back to `"application/json"` as the
default media type for servers and clients.
Closes gh-375
The GraphQL HTTP spec now requires the `"application/graphql+json"`
content type.
This commit applies this type by default in the server and client
implementations. `"application/json"` is still accepted and produced if
requested by clients.
Closes gh-108
The default transport-specific client and tester extensions contained
their builder implementations, but it makes more sense the other way
around since the extensions are mainly about the builders they provide.
Use more qualified names [Web|Socket]GraphQlHandlerInterceptor to
differentiate with ClientGraphQlInterceptor and to align with other
types in the same package.
