npm start fails on windows

[dwsmart]

Hi All,

I tried npm init qwik@latest on a windows 10 machine

Chose the starter, did cd qwik-app npm install

Did npm start, all good so far,

Tried to go to http://localhost:8080 in a browser, this fails, and outputs this in the console

node is version 16.13.1

Am I missing a step? Perhaps windows isn't supported?

@manucorporat I think this issue is for you.

I have investigated the problem, and it seems that on Windows the Optimizer is bypassed. Not sure as to why but the generated code is the original code without code splitting. Something about Windows file-paths (my guess) must be confusing the optimizer in a way that is preventing it from doing its job.

The failure mode is that the code generated on windows is similar too:

const MyCmp = qComponent({
  onRender: qHook(() => <span>ABC</span>)
})

Whereas the correct code should be:

const MyCmp = qComponent({
  onRender: qHook('./path#symbol')
})

PS: I have created a better error msg for this condition: #127

If I understand the correct result, transforming by the executable qwik.exe doesn't reproduce the problem.
