GOJS VUE Vue cli -> Vite migration

Question

I have a large vue 2 project that I am migrating from vue cli to vite and I am down to one dependency that is not working. I use gojs 2.1.51 in my project for many years now but when using the same code and data but using vite instead of vue cli I get

chunk-JHIOXJJP.js?v=d4bd4acf:2020 TypeError: Cannot set property layer of [object Object] which has only a getter

Anytime I try to add a groupTemplateMap
sd.diagram.groupTemplateMap.add(...)

If I switch back to using the vue cli instead of vite it works just fine.  I known there is not a lot of information here to help debug, but I just wanted to know if anyone else has run into issues with gojs and vite or got it to work.

Answer 1

The issue, if anyone else runs into this, turned out to be a combination of a bad GOJS argument and the way Vite compiles GOJS. Instead of getting a GOJS error, like we do with webpack, I got an exception deep in the minimized GOJS code. The GOJS team was great in helping debug this issue.

From the GOJS team: use method chaining instead of our $/go.GraphObject.make, it should be able to give you more sensible errors.
