Course Overview

Traditional REST APIs often constrained developers who needed more granular approaches without creating a huge collection of unnecessary calls. This results in high latency and high cost.

GraphQL—a query language for APIs—allows developers to choose the kinds of requests they want to make and receive information on multiple facets of that query in a single request. The GraphQL approach to querying across networks can address a wide variety of large-scale development problems.

In this course, you will learn the difference between REST and GraphQL, how to get started with GraphQL step by step learn the basics of this query language, schema, resolvers, fetching data, and getting you up to speed with the syntax and vocabulary of GraphQL. You will also take a look at Apollo and AWS AppSync to build GraphQL APIs. You will also develop an API for a modern Blogging web application.
