import { buildASTSchema } from "https://deno.land/x/kilatgraphql@16.6.0-1/mod.ts";
This takes the ast of a schema document produced by the parse function in src/language/parser.js.
If no schema definition is provided, then it will look for types named Query, Mutation and Subscription.
Given that AST it constructs a GraphQLSchema. The resulting schema has no resolve methods, so execution will use default resolvers.
Parameters
documentAST: DocumentNode
optional
options: BuildSchemaOptions
