View Source Absinthe.Introspection (absinthe v1.7.6)
Introspection support.
You can introspect your schema using __schema
, __type
, and __typename
,
as described in the specification.
Examples
Seeing the names of the types in the schema:
"""
{
__schema {
types {
name
}
}
}
"""
|> Absinthe.run(MyApp.Schema)
{:ok,
%{data: %{
"__schema" => %{
"types" => [
%{"name" => "Boolean"},
%{"name" => "Float"},
%{"name" => "ID"},
%{"name" => "Int"},
%{"name" => "String"},
...
]
}
}}
}
Getting the name of the queried type:
"""
{
profile {
name
__typename
}
}
"""
|> Absinthe.run(MyApp.Schema)
{:ok,
%{data: %{
"profile" => %{
"name" => "Joe",
"__typename" => "Person"
}
}}
}
Getting the name of the fields for a named type:
"""
{
__type(name: "Person") {
fields {
name
type {
kind
name
}
}
}
}
"""
|> Absinthe.run(MyApp.Schema)
{:ok,
%{data: %{
"__type" => %{
"fields" => [
%{
"name" => "name",
"type" => %{"kind" => "SCALAR", "name" => "String"}
},
%{
"name" => "age",
"type" => %{"kind" => "SCALAR", "name" => "Int"}
},
]
}
}}
}
(Note that you may have to nest several depths of type
/ofType
, as
type information includes any wrapping layers of List
and/or NonNull.)
