How do I install viewer dependencies: npm i @combeenation/3d-viewer?
Hi @Innolto,
Yes that’s correct.

But where can i execute this command?
Hey @Innolto,
you must execute the npm command in a command line on your own machine, but that requires some setup. In case you’re not familiar with npm at all, here is a short summary on it:
We also have documentation on how to set up a development environment for extending Combeenation configurators with Custom JavaScript:
https://docs.combeenation.com/docs/custom-js
That page also explains how to build your JavaScript code to turn it into a single, production-ready .js file that you can then upload to your configurator.
If you are new to JavaScript development, then it will be a bit of a hurdle to get this all set up. On the plus side, you will then have access to all sorts of useful npm packages and a powerful editor like Visual Studio Code.
