GraphQL Query Language
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.
What you'll learn:
- Query, mutation, & subscription
- GraphiQL playground
- Schema
- Fragments
- Variables
- Input types, unions, interfaces, & return payloads
- Introspective Queries
