Stepwise editor

With the release of the stepwise editor, developers are now able to better guide users through the editor by dictating the order of pages that a user visits. This means that instead of being able to freely move between pages, users move to the next or previous step with a ‘next’ or ‘previous’ button at the bottom of the page. We think that this makes it easier for users to efficiently use the app and that it helps with increasing the integrity of the data used in the calculations and the app’s overall usability.

Steps are defined in the parametrization similar to a ‘Page’, where the labels on the buttons can be customized too.

Find out how you can add steps to your apps in the documentation!


Dynamic Array Row Label

To make it easier to see which input a user is working with when generating a dynamic array with many inputs, we have added an index number to the dynamic array entries. Developers can also define a row label which will be shown behind the row number.

More information on the dynamic array row label can be found in the documentation.

Redesign of DataView

An improved design of the DataView has been released that presents a better distinction between levels/layers.

This leads to a better and clearer navigation, which especially improves the experience of analyzing results in an elaborate DataView.

Python Virtual Environments for App development

At VIKTOR, we are continuously working on improving developer experience. That is why we are soon releasing functionality that enable the development of apps using Python virtual environments as isolation mode, instead of Docker. For Windows users, this removes a cumbersome step from the installation process, enabling native development and going from zero to a running app even faster!

Please note

In addition, Docker is changing the subscription model of Docker Desktop at the beginning of February. A possible consequence, depending on company size and company revenue, is that use of Docker Desktop requires a paid subscription from then on. If you use VIKTOR with a Python virtual environment, Docker is no longer a prerequisite to develop applications on the platform, so it is possible to keep using VIKTOR without the need for an additional Docker subscription.
