GraphQL Query Language
Instructor
Eve Porcello
GraphQL is gaining traction as one of the most popular ways to create an API. Regardless of which GraphQL implementation you pick, you’ll use the QL in GraphQL — the query language — to query data, change data with mutations, and listen for data changes with subscriptions.
You need to know the Query Language regardless of the server-side implementation. In this course, we will learn the GraphQL query language by sending an assortment of GraphQL operations to an existing API.
To start, we’ll learn how to write queries to obtain all the data needed for an app in one response. As the course progresses, we’ll use mutations to add and change data. To wrap up, we’ll investigate GraphQL subscriptions and realtime data.
After the course, you’ll be ready to communicate with a GraphQL API regardless of server-side implementation using the GraphQL query language.

Well structured, easy to understand, based on examples.
- blainewishart4 years agoWhat did you like about this course?
The concepts are skillfully woven together. Progress is incremental and step x often provides the motivation for step x+1. Enunciation and language are precise. [My hearing is imperfect.] Concepts like interface are well motivated, explained, and demonstrated. I'm kicking myself for not looking at this material sooner. I gave this a 7. By that standard, any course that gets a 4 is high quality and worthwhile.
