GraphQL Core
Learn the basics of GraphQL
Description
You'll learn how to build and use a GraphQL API in this hands-on training. We thoroughly cover the core components of GraphQL: the strongly typed language, the schema and the resolvers. You'll write code yourself to fetch and alter data and you'll also learn how GraphQL supports real-time data.
Because a GraphQL implementation is available for almost every programming language, we'll use JavaScript in this course and will make it as accessible as possible. Nodejs and Apollo Server will act as backend platform. Knowledge of these is not required.
Prior Knowledge
Programming experience. Knowledge about JavaScript is a plus, not a requirement.
