This Typescript package can be used to validate cypher queries. With the help of a simple schema, the validator will check and correct the directions of relationship patterns.
There is only one public API and that is the "validate" method:
type RelationshipTuple = {
sourceLabel: string;
relationshipType: string;
targetLabel: string;
};
function validate(cypher: string, schema: RelationshipTuple[]): string;
It will return '' for invalid Cypher and will otherwise correct the arrow heads on directed queries to match the schema, when possible.
