QR code won't scan

[timurtu]

After creating an app and running yarn start the QR code gives no feedback when scanning on my iPhone.

Did you install the Expo app?

[timurtu]

Yeah I don't get any feedback when I scan the QR code with the Expo app

[jesseruder]

Hm not sure why that's happening. Can you upload a screenshot of the QR code? If you can't get it working you can type the url in manually - just go to the Explore tab in Expo and then type the url in the search bar.

[timurtu]

Yeah I just tried that it loaded here's the screenshot.

It looks like it might be a little squished horizontally. @dikaiosune do you think we can do anything about that?

Interesting! I suspect that the horizontal scaling isn't the actual problem (I've seen it work well on much more squished consoles), but rather the contrast between the dark and light elements is. IntelliJ/Webstorm's terminal appears to have interesting ideas about how to render bash color codes!

I'm not sure what we can do about this. It might be possible by changing the Webstorm color theme, the font, or by trying in a different terminal.

Using a terminal worked great

Glad to hear it!

Sorry, I'm going to leave this open as we need to at the very least document this issue.

Is there a way that the QR code can be generated into a PNG (or something similar)? So that it could be pasted into a GitHub repo or Gist so users can quickly open it within Expo.

[anp]

While it's definitely possible from an implementation perspective, I'm not sure we want to add any more complexity to the startup scripts.

Generally if you want to share the app with someone they'll need to be on the same LAN and I'm mostly thinking that it's not unreasonable to expect them to be able to physically scan the phone.
