node graphql firestore api tutorial

Introduction

This tutorial tries to elaborate, "How to create a graphQL-API with node js".

Grapqhl is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. Documentation for the same can be found here
