Hi @hudo,
The reason there are no v14 docs is that v14 reached end-of-support on May 30, 2025.
In terms of upgrades, you can go straight from v13 to v16, (and/or v17 once it’s released on November 27, 2025).
As for an answer to your issue with the dashboards, there is a package available for v15 that enables you to register a dashboard in C# and use a Razor view to render the dashboard.
As for the “overkill and overengineering” of a Vite/TS project, I hear you, as do others. The arguments and explanations have been made several times on the forum, if you wanted to read up on these.
With the new (current) backoffice, it’s pure JavaScript/WebComponents, in which you can develop these however you like. The main reason for the focus on Vite/TS is that once you get into more advanced scenarios, those tools become very useful, (for type-safety/intellisense, bundling/minification, package builds, etc), so it’s a steeper learning curve upfront, which will hopefully pay-off later. Of course, any suggestions on ways to simplify this are very welcome.
