extract-field-coordinates

Statically extract a list of "field coordinates" contained in a GraphQL document

Install

$ yarn add --dev extract-field-coordinates

Example

e.g. for the following query:

query GET_BUSINESS($BizId: String) {
    business(id: $BizId) {
        name
        location {
            city
        }
    }
}

We would return the following set of field coordinates:

["Query.business", "Business.name", "Business.location", "Location.city"]

     * @see https://graphql.org/graphql-js/utilities/#printschema
     */
    schemaText: string,
): Set<string>
