Yeah for me too. Got some other errors now when running my app which I reported elsewhere.

I upgraded and the preset is included in my babel.config.js . When running dev script on my app I get:

> Executing task: npm run dev <

I tried both npm and yarn, but both give same problems on a project that was working fine on v1 beta. After deleting node_modules and package-lock.json and reinstalling I get error saying all kinds of packages missing and suggesting to install them with:

But these seem core-js files so I am puzzled…?!

Exact same here.

@metalsadman Great! Thanks!

@metalsadman You’re right: mount should be function. However: in your version the picture the file.__img does not load either…, which was the point. The errors in the console are just showing up in codesandbox (for both the ‘one-component’ and ‘parent child’ solutions => should not matter) and are indeed related to quasar version (I found a related issue, which now is solved). I tried/ looked up using quasar v17 with codesandbox, but don’t know how to do it (you install the entire cli…?).

I am trying to split the quasar uploader into a parent and children, but the file property does not work somehow… Anyone can tell me why? See here for full details.

Would be cool have this one ‘setup’ as well:

See this for a solution and whether that’s how it should be done…:

@Jaxon No, sorry. I got this answer recently, but it does not answer your issue: https://stackoverflow.com/questions/49616642/jest-unit-testing-config-with-quasar-framework-0-15

I gave up on Jest for now and work happily with cypress (use it for e2e, and some unit-testing when necessary…).
