This seems to affect all templates apart from React... (On Linux)

Ok, this seems ok on mac... which is odd as the code base for serve is not platform dependent... Still investigating. Here is a test matrix. It would be great if you could give feedback on the windows combinations!

| OS | Template | Working? |
| ----- | ----- | ----- |
| Mac | Vue | ✅|
| Mac | Vuetify | ✅|
| Mac | Angular | ✅|
| Mac | React | ✅|
| Linux | Vue | ✅|
| Linux | Vuetify | ✅|
| Linux | Angular | ✅|
| Linux | React | ✅|
| Windows | Vue | ❌|
| Windows | Vuetify | |
| Windows | Angular | |
| Windows | React | |

Absolutely no idea about Angular / React and I don't need Vuetify, sorry
So on Windows/Vue : it does not run
maybe other people could help to check

Updated table after doing more testing on Linux.

I have the same problem on Ubuntu 18.04 using Vue. This started occurring after the 0.18 update. Building and running it using GTK works fine. Chrome reports the same as stated by OP. FF reports "TypeError: window.wails is undefined"

[leaanthony]

Please try v0.19.0-pre2 and let me know. It assumes you will generate a new
project or update your version in go.mod
