SYNOPSIS

  package GraphQL::Plugin::Convert::DBIC;
  use Moo;
  extends qw(GraphQL::Plugin::Convert);
  # ...

  package main;
  use Mojolicious::Lite;
  use Schema;
  use GraphQL::Plugin::Convert::DBIC;
  helper db => sub { Schema->connect('dbi:SQLite:test.db') };
  my $converted = GraphQL::Plugin::Convert::DBIC->to_graphql(app->db);
  plugin GraphQL => {
    map { $_ => $converted->{$_} }
      qw(schema resolver root_value)
  };

  # OR, for knowledgeable consumers of GraphQL::Plugin::Convert APIs:
  package main;
  use Mojolicious::Lite;
  use Schema;
  helper db => sub { Schema->connect('dbi:SQLite:test.db') };
  plugin GraphQL => { convert => [ 'DBIC', app->db ] };

DESCRIPTION

Abstract class for other GraphQL type classes to inherit from and implement.

METHODS

to_graphql(@values)

When called with suitable values (as defined by the implementing class), will return a hash-ref with these keys:

schema

A GraphQL::Schema.

resolver

A code-ref suitable for using as a resolver by "execute" in GraphQL::Execution. Optional.

root_value

A hash-ref suitable for using as a $root_value by "execute" in GraphQL::Execution. Optional.

from_graphql

When called with a hash-ref shaped as above, with at least a schema key with a GraphQL::Schema, returns some value(s). Optional to implement. If the plugin does implement this, allows conversion from a GraphQL schema to that plugin's domain.
