GraphQL Development
Learn GraphQL
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 to support real-time data.
The training also covers advanced topics such as enumerators, interfaces, unions and directives. Best practices are also given on topics such as authentication and authorization.
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, Apollo Server and Prisma will act as backend platform. Knowledge of these is not required.
This training is a combination of two courses. The first day is course GraphQL Core, the second day is course GraphQL Advanced. See 'related courses' below.

HTML and CSS: Front-End Development
Developing web applications with HTML and CSS
The web is growing considerably in popularity. More and more functionality is shifting towards the client and small revolutions are happening. Think of the advent of SPAs and PWAs, the dying out of Flash/Silverlight, realising server-side solutions with Node.js/Deno and building desktop applications with Electron.
This course builds a solid foundation for working with HTML and CSS. You will learn how CSS frameworks and preprocessors aid in maintaining your stylesheets. You will also learn to work according to the latest features that modern browsers provide with HTML5 and CSS3. Finally, you will learn about the JavaScript APIs that come with HTML5, such as storage, geolocation and web sockets.
This course is a combination of two other courses. The first 3 days correspond to the course Core HTML/CSS. The last 2 days correspond to the course Advanced HTML/CSS.
In this module, you will learn to apply HTML.
