I was not able to run example about qmlweb

[bessorion]

In addition, lib-folder from npm package was able to run example app, but I suppose master-version supports more default qml components. Am I right?
Again, could you help me run at least example on last sources? I have to port existing qt-qml app to the web and going to use your library instead of rewriting the whole app on Angular if it's possible.

I receive the same error when I try to run npm i && npm run coverage :
Uncaught TypeError: Super expression must either be null or a function, not undefined at tmp/qmlweb.covered.js:125228
It looks like new module syntax and ./builder/shaker.js script doesn't normalize classes sequence by dependencies, so QmlWeb_Dom_DomElement defined earlier than its parent QtQuick_Item. To make sure you can take a look into newly built qmlweb.js file

Hi! Sorry for the delayed response, looking at it.

[ChALkeR]

Thanks for the report and the investigation.

npm i && npm run coverage works for me and the log doesn't have anything about Super.
Which Node.js verson are you using?
Have you done any modifications?

Could you try cloning into a clean dir again and re-running npm i && npm run coverage from it?
Also, the line numbers in tmp/qmlweb.covered.js don't seem to match — mine is column: 8 on that line.

It looks like new module syntax

That should be processed with babel. The TypeError could be thrown from babel, but not sure why.

./builder/shaker.js script doesn't normalize classes sequence by dependencies

A possible explanation is that the class order is incorrect for some reason…
Could you do grep -E '^\s\sfunction\s' tmp/qmlweb.covered.js and attach here or to a gist, please?
Alternatively, attaching the whole file would also do.

[bessorion]

I'm so happy you've finally answered )
I'm afraid I cannot use grep on windows, so I'll attach the whole file.

tmp.zip

C:\Users\BeSSoRioN\Documents\GitHub\qmlweb>node --version
v8.11.1

I tried to build and run clean repo from github, so I suppose no changes was performed exclude node_modules folder

Please let me know if you need something else

[bessorion]

I searched through the file and the same initialization order I'd seen during debug procedure with firebug: some base classes was instantiated normally (placed in ./src/qtbase and ./src/engine), then QmlWeb_Dom_DomElement throws exception (why is it the first from ./src/modules ?)

[ChALkeR]

Yes, I can confirm that the order is indeed incorrect in your build. Thanks for that file!

I reproduced the build that you have, and I suppose that the error is somewhere somewhere along this line: https://github.com/qmlweb/qmlweb/blob/master/builder/shaker.js#L50, i.e. my guess would be that relative.startsWith(prefix) always fails on Windows. Could be caused by different path normalization, looking at it.

@bessorion See #433.

Try testing windows-shaker branch — check it out, remove lib and tmp dirs (just in case) and re-run.
I believe it contains a fix.

Alternatively, you could try replacing require("path") with require("path").posix in shaker.js.

[bessorion]

Current problem seems to be fixed. At least I have no more errors during library loading. You can merge windows-shaker branch to the master.
Unfortunately, I still have many problems with my existing qml-app sources.
Will provide information little bit later
