fyne serve default target

[srackham]

The default fyne serve command target is "web" which requires the gopherjs compiler, which in turn only supports up to Go 1.18, so unless you use an old version of Go you get an error like:

$ fyne serve
GopherJS 1.17.2+go1.17.9 requires a Go 1.17.x distribution, but found version go1.21.5

Would it make more sense to have wasm as the default target, or am I missing something?

Now that Go has WASM compilation support, does it make any sense to have a "gopherjs" (JavaScript) target?

You don't have to use Go 1.18, you can use any as long as the older install is also there, see: https://developer.fyne.io/started/webapp.

There is an ongoing discussion, see #4330, it was considered on our latest contributor call that perhaps GopherJS should not be included going forward. It is being discussed.

However in response to the actual question - no, the technology should not be the name of a OS target as that's an implementation detail. A relevant question could be "should GopherJS be disabled by default" which makes this a duplicate question.

Brilliant! Thanks for the super-fast response. As I work through the Fysion videos I continue to be amazed, until I stumbled on Fyne I had given up on cross-platform GUI development.

I'm very glad this is exciting - so much is possible but there is a lot more to come in the year ahead. :)
