Introduction to GraphQL

The Introduction to GraphQL training course brings you up to speed with modern API
development with GraphQL.

The GraphQL course covers the various types of the GraphQL ecosystem and how to write
queries and mutations using those types.

During the course, you will use the GraphQL web-based client to execute queries before
transitioning to the web browser’s fetch API to query for data and display it with React Components. Performing
mutations with React Components and GraphQL is covered as well.

While there is some server-side coding withNode.js, the focus of the class is on client-side coding and consuming GraphQL APIs, not how to create them.

Note: Prior working knowledge and practical experience of Modern JavaScript and React is assumed for this course
