What's new in VIKTOR (November 2022)


The time has come for November's platform update. Over the past month, we have been working on a new app type called editor, a dedicated page for apps, and a functionality that lets you assign maintainers to an application.  Sounds interesting?

Create apps with only an editor

We have created a new app type called editor that allows you to easily create applications with only one page! Implementing the editor app type will be the same as for the recently introduced simple app type. However, with the editor app type users will directly enter the editor after opening a workspace, making it easier to navigate. This is especially useful if you don't require any data saving, for example when you are creating a dashboard or calculator app.    Find more information about the different app types in the documentation

Dedicated page for apps

We have added a new page to the environment where developers and admins can view, create, and update all their (organization’s) apps. When opening an app from here, you will find information such as a description of the app, its maintainers, and details about the most recent and previously published versions (date, developer). The new Apps page gives us a lot of opportunities to add additional features, such as fine-grained control over the maintainers of apps. Keep on reading in the next highlight for more details.    For more information about the Apps page, please visit the documentation.

Apps vs. Workspaces

The difference between an app and a workspace can be difficult. To make sure all is clear, we will quickly explain both concepts. 

A normal user mainly interacts with workspaces: this is where calculations can be made. Developers and admins however also interact with apps. Apps contain all a programmer's logic and code: how the app is structured, how input is organized, what the output looks like, and what calculations should be performed. In short, a workspace is an app plus data (from users and calculations).

Assign developers to apps

You can now assign maintainers to your apps. Maintainers are the only developers that have the rights to publish new versions of an app. They also receive error reports on workspaces using this app. This way, access to sensitive app logic can be limited.
