Grohden / deep-typename-apollo.ts

Created August 9, 2019 03:06

Fn to put deep __typename based on keys for apollo gql (apollo link rest is too verbose)

	* requires __typename to be injected)

	typeNames: object
	) {

	: P extends Primitive

	input tap 683 614
	input tap 950 411
	input tap 1188 248
