Have you heard about GraphQL? Have you always wanted to understand the basics of GraphQL? This course is for developers who wish to learn about GraphQL in a practical, hands-on manner.

During the course, you will acquire the necessary skills to understand and work with GraphQL's basic as well as advanced features, including but not limited to:

Have a basic understanding of basic scalar types
Create custom scalars
Be familiar with Resolvers and Type Definitions (Schemas)
Understand the importance of a data model in relation to GraphQL
Understand how GraphQL queries work, including parameterised queries
Get a working knowledge of GraphQL mutations
Understand how file uploads work using GraphQL
Learn how to serve images in a GraphQL context
Go hands-on and learn how authentication and authorisation works in GraphQL
You'll create four sample applications:

Implement a basic application to run GraphQL queries
Implement a more advanced application that uses React to work with GraphQL
Enhance the aforementioned application and extend it with authentication and authorisation
Create an application to understand how to serve/display images and upload files using purely GraphQL
This course mostly utilises the Apollo GraphQL services.

Please note that during the course, several applications are created-mostly using React-however this course does not contain information on React. It does discuss the React parts that are relevant to the context, so only students who are already somewhat familiar with React should purchase this course.
