Single Page Applications without REST API
Single Page Applications (SPAs) use a REST API as a bridge between client and server for communication. This API must be developed and tested and access code has to be written on the client side. This process is complex and error-prone. Vaadin Fusion takes a different approach and generates the API and the client-side access code based on annotated Java classes.
This talk is an introduction to Vaadin Fusion. In contrast to the well-known Java-based Vaadin Flow, Vaadin Fusion offers the possibility of developing SPAs with TypeScript and web components in the frontend and Java in the backend.
