Actix-web

Async-graphql-actix-web provides an implementation of actix_web::FromRequest for GQLRequest. This is actually an abstraction around QueryBuilder and you can call GQLRequest::into_inner to convert it into a QueryBuilder.

WSSubscription is an Actor that supports WebSocket subscriptions.

Request example

When you define your actix_web::App you need to pass in the Schema as data.

async fn index(
    // Schema now accessible here
    schema: web::Data<Schema>,
    gql_request: GQLRequest,
) -> web::Json<GQLResponse> {
    web::Json(GQLResponse(gql_request.into_inner().execute(&schema).await))
}

Subscription example

async fn index_ws(
    schema: web::Data<Schema>,
    req: HttpRequest,
    payload: web::Payload,
) -> Result<HttpResponse> {
    ws::start_with_protocols(WSSubscription::new(&schema), &["graphql-ws"], &req, payload)
}
