This library contains means of transforming raw GraphQL ASTs (as produced by e.g. alumbra.parser) into formats more suitable for validation or execution. It is based on the specs defined in alumbra.spec.
(require '[alumbra.analyzer :as analyzer])Schema Analysis
Converts a value conforming to :analyzer/schema to :analyzer/analyzed-schema
which can be used as a base for GraphQL query document validation. This
operation needs to have a parser injected, since internally it will merge
the GraphQL introspection schema into the given one.
(analyzer/analyze-schema
"type Person { ... } ..."
alumbra.parser/parse-schema)Note that this operation assumes that the input schema has been validated and is thus semantically sound.
Canonical Operation Generation
Based on an analyzed schema, a value conforming to :analyzer/document can
be converted to :analyzer/canonical-operation which is a self-contained
format suitable for execution.
(analyzer/canonicalize-operation
analyzed-schema
(alumbra.parser/parse-document "{ me { name } }"))Note that this operation assumes that the input document has been validated and is thus semantically sound.
