Course Overview

GraphQL is an API query language that allows clients to ask for exactly what they need and nothing more makes it easier to evolve APIs over time. This course is divided into three parts, Part 1- Build a GraphQL API, Part 2- Publish Your API, and Part-3 Use Your API. In the first part, you will cover topics ranging from basic GraphQL, Building GraphQL Schema, Taking User Input, Adding Flexibility, Making a Change with Mutations, and Going Live with Subscriptions. In the second part, you will cover topics...Show More
