The various GraphQL clients supported in this project automatically detect
JSON codecs for reading/writing GraphQL requests as JSON payloads.
If there is none detected, clients provide a default codec instance.
This commit configures automatically the `GraphQlModule` from gh-1174 in
default codecs and add integration tests for `FieldValue<T>` usage on the
client side.
This also improves the documentation around `FieldValue<T>` for both
server and client side support.
Closes gh-1190
This commit adds a new `GraphQlModule` Jackson module that supports:
* serialization/deserialization of `FieldValue<T>`
* the upgrade of `FieldValue<T>` as reference types
This enables `FieldValue<T>` to be read/written from/to JSON with
Jackson on the client side. Note, on the server side this module is not
involved as the payload is deserialized as a `Map<String,Object>` and
values are bound as `FieldValue<T>` types directly.
Closes gh-1174

Prior to this commit, the "client" and "testing" sections of the
reference documentation were using inline code snippets.
Because of this, several snippets were out of date or invalid.
This commit moves all those code snippets to actual Java classes
compiled with the documentation.
Fixes gh-1042
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
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
