Introduction to GraphQL

Course Summary

Simplify your backend with GraphQL, the new query language and runtime that is taking the world by storm. With GraphQL, it’s no longer necessary to resolve a bunch of different REST endpoints to get a complete chunk of data. We can use GraphQL to tell a server which data we want, and exactly what it should look like. Whether you’re a front-end developer looking to simplify your workflow, or a back-end developer looking for a way to compose more robust APIs, this course is the perfect place to start.
