graphql parser + utilities

graphql

utilities for dealing with GraphQL queries in Go.

This package focuses on actually creating GraphQL servers and expects you to describe your schema directly in Go.

To that end this library initially has not emphasized GraphQL schema definition parsing and instead focuses on Query Documents and writing real servers.

graphql's Issues

Kind of types support

Hi, thanks for a well written library.

I'm trying to add GraphiQL support to handler and got some errors in introspection query because
the returned schema is missing the "kind" of types(OBJECT, INT, STRING etc.).

I can't find in the source code any reference to kind implementation.

Do I need to implement it by myself or have I missed something?

schema print

Is there an option to print the schema as json. This is needed to use with relay for validation. similar to https://github.com/relayjs/relay-starter-kit/blob/master/scripts/updateSchema.js

How to parse variables and operationName ?

I want to pass this string and get it parse, can someone help please?

{ "operationName":"myOperation", "variables":{ "var1":216 }, "query":"query myOperation($var1: Int!) {\n myOperation(var1: $var1) {\n basic_info {\n id\n name\n mobile\n alt_mobile\n image_url\n language\n __typename\n }\n profile_details {\n employee_type\n __typename\n }\n __typename\n }\n}\n" }

Schema Incomplete?

Hey there!

I came across this project and was really excited. I had been planning on implementing a GraphQL server in Go, and now I don't have to [=

I decided to try adding the Star Wars Schema tests from Facebook's sample implementation in JS but ran into a few issues. You can see my start in this commit, but I'm getting confused on how to put together a more complicated, typed schema. I couldn't find any examples or tests in your repo.

It looks to me like some of the schema definition stuff might not be complete? I'd be happy to work on this, but wanted to make sure I wasn't just mis-interpreting what's here already.

Thanks in advance!

Better docs please

How do you run the server? Make a query?

support introspection query from graphiql

As mentioned in #3

When connect with graphiql, the initial introspection query gives error.

error: {message: "No handler for field 'queryType' on type '*schema.Schema'"}

query: (as see in the terminal log)

  query IntrospectionQuery {
    __schema {
      queryType { name }
      mutationType { name }
      types {
        ...FullType
      }
      directives {
        name
        description
        args {
          ...InputValue
        }
        onOperation
        onFragment
        onField
      }
    }
  }

  fragment FullType on __Type {
    kind
    name
    description
    fields {
      name
      description
      args {
        ...InputValue
      }
      type {
        ...TypeRef
      }
      isDeprecated
      deprecationReason
    }
    inputFields {
      ...InputValue
    }
    interfaces {
      ...TypeRef
    }
    enumValues {
      name
      description
      isDeprecated
      deprecationReason
    }
    possibleTypes {
      ...TypeRef

  }

  fragment InputValue on __InputValue {
    name
    description
    type { ...TypeRef }
    defaultValue
  }

  fragment TypeRef on __Type {
    kind
    name

      kind

        kind

          kind

        }
