An exampleGraphQL server written withakka-http,circe andsangria.
After starting the server with
sbt run# or, if you want to watch the source code changes sbt~reStart
you can run queries interactively usinggraphql-playground by openinghttp://localhost:8080 in a browser or query the/graphql endpoint directly. The HTTP endpoint followsGraphQL best practices for handling the HTTP requests.
Here are some examples of the queries you can make:
$ curl -X POST localhost:8080/graphql \ -H"Content-Type:application/json" \ -d'{"query": "{hero {name, friends {name}}}"}'
this gives back the hero of StarWars Saga together with the list of his friends, which is of course R2-D2:
{"data": {"hero": {"name":"R2-D2","friends": [ {"name":"Luke Skywalker" }, {"name":"Han Solo" }, {"name":"Leia Organa" } ] } }}Here is another example, which uses variables:
$ curl -X POST localhost:8080/graphql \ -H"Content-Type:application/json" \ -d'{"query": "query Test($humanId: String!){human(id: $humanId) {name, homePlanet, friends {name}}}", "variables": {"humanId": "1000"}}'
The result should be something like this:
{"data": {"human": {"name":"Luke Skywalker","homePlanet":"Tatooine","friends": [ {"name":"Han Solo" }, {"name":"Leia Organa" }, {"name":"C-3PO" }, {"name":"R2-D2" } ] } }}About
