import { getDirectiveValues } from "https://deno.land/x/graphql_deno@v15.0.0/mod.ts";
Prepares an object map of argument values given a directive definition and a AST node which may contain directives. Optionally also accepts a map of variable values.
If the directive does not exist on the node, returns undefined.
Note: The returned value is a plain Object with a prototype, since it is exposed to user code. Care should be taken to not pull values from the Object prototype.
Parameters
directiveDef: GraphQLDirective
node: { readonly directives?: ReadonlyArray<DirectiveNode>; }
