goappGetenv is not a function, got undefined

[elfprince13]

main.main() panics in app.RunWhenOnBrowser when running even a trivial example.

panic: syscall/js: Value.Call: property goappGetenv is not a function, got undefined [recovered]
wasm_exec.js:22 	panic: syscall/js: Value.Call: property goappGetenv is not a function, got undefined

If I upgrade from v9 to v10 I instead get:

panic: JavaScript error: Failed to execute 'replaceChild' on 'Node': parameter 2 is not of type 'Node'. [recovered]
wasm_exec.js:22 	panic: JavaScript error: Failed to execute 'replaceChild' on 'Node': parameter 2 is not of type 'Node'.

Well. I guess you need to show us the code for that trivial example.

I currently have no V10 based public project (but we use V10 since months for our products). Maybe try something we published with V9 in the meantime:

• https://github.com/oderwat/go-guess-the-number-app
• https://github.com/metatexx/go-app-todo
• https://github.com/oderwat/go-nats-app

I think the only needed change for V10 is using app.NewZeroComponentFactory(&component{})) with the app.RouteX() but there may be other little things to adjust.

I literally just copy-pasted the examples from the site and renamed the module for a project I'm testing.

I checked out and built your go-guess-the-number-app with no errors, but running app and navigating to localhost:8000 shows a page with a broken image that says:

TypeError: import object field 'gojs' is not an Object

Let me check https://github.com/oderwat/go-guess-the-number-app .. this is very old and I forgot that I had this there.

In case it makes a difference, I'm compiling with go version go1.22.3 darwin/arm64, but not getting any compilation errors, only runtime errors.

[oderwat]

That is the reason for this one error. The gojs changend between the time my code was written and now. This can't easily be captured by the package.

I quickly rewrote my https://github.com/oderwat/go-guess-the-number-app for V10. Use make run and open http://127.0.0.1:8000

Please tell me if it works for you. I may also update the other examples asap.

For posterity - it seems the cluster of related issues here is that there are a bunch of files needed to serve the site statically which can only be generated with app.GenerateStaticWebsite. I'll open a fresh issue when I have a better sense of the workflow that I actually want for this.
