Migration to a modern HMI framework

The challenge

MULTIVAC uses a central software framework to scale development capabilities across its various business areas. A uniform design and technical implementation of the user interface (HMI) is important, as the products from the individual business areas are often combined to form complete solutions. The existing HMI framework was based on the JavaScript library Polymer, whose further development has been discontinued. This led to security issues and limited the ability to introduce new features. In addition, Polymer’s slow performance was a serious problem. In order to future-proof the user interface and significantly improve its speed, all Polymer components had to be replaced with modern technology (Vue.js).

How we helped

To overcome these challenges, we supported MULTIVAC in migrating from Polymer to Vue.js, a modern JavaScript technology for web applications. This significantly improved performance, which in turn greatly increased operating speed and user-friendliness. Our team helped the developers learn the new technologies and carried out the conversion of numerous components in various business areas. At the same time, we ensured that the central framework, which provides the core components, met the performance requirements. To guarantee high quality and efficiency, we introduced test automation that performs software tests automatically and regularly. We also implemented interactive documentation that enables users of the framework to work directly with sample components and illustrates their application in programming.
