At first I was like "OMG, this is going to be awesome, this person has a QR generator which will magically connect me to the WiFi with my password embedded in the QR somehow. I am going to have to read the source... This is gonna be great... but then, disappointment. It is just a card with my password in plain text. Why the heck would I ever print this out?

  a QR generator which will magically connect me to the WiFi with my password embedded in the QR somehow.

This is indeed what it does, but it also includes the plaintext password in case you want to connect a device that doesn't have a camera, like a PC. There's an open issue for adding a "hide password" option. You could also just cut off or scribble out the password on the print out.

It depends on the qr-code scanner you have on your phone. The one on my android shows a button 'connect to this network'.

In regards to security, you are completely correct. But this is to be used in cases where one would put a paper with the password on the wall, think of coffee shops. Saves some typing. Or you can put a card on your coffee table to help out your house guests.

To be slightly snarky, because the author wants to record your WiFi and Password.

That it was a learning project, ok. I guess.

I’m guessing the whole point behind the “standard” is to allow quick and easy access to protected networks. It’s an alternative / compliment to verbally telling someone the passphrase, or having it printed in clear text on a paper.

Think of hotels / offices with guest networks. I use it for my wifi, my home network is not secretive enough to not let friends / family join it when at my place.

Earlier quoted context omitted.

This method picks up "most" requests, but not all. eg. websocket and webrtc can be used to exfiltrate data but it won't show up on inspector.

They do show up, not the connections themselves, but the initiation, no?? At least I always see lots of 101 Switching Protocols responses on sites that use websocket, it might be some sort of nonstandard gateway though. Never used it so dunno. Of course even if that's the case, you gotta load the website with the network inspector already open, to see the initiation.

You can "hide" a websocket connection behind a shared worker and that won't show up in the network connection tab.

I do that on a site of mine, but for a less nefarious reason: sharing a websocket connection between multiple tabs.

I thought that was crazy, but reflecting over my CS education they haven’t gone over the difference between disk space and RAM. I suppose they figure everyone already knows?

I think that's why Scott Hanselman started this series https://www.hanselman.com/blog/new-youtube-series-computer-t...

People love to constantly say "Want to learn to code? Make projects! projects! projects!" and then when someone makes a project as a means to learn a particular technology, now people turn up their nose and say "ew, why did you use this?"

Anyway, this project provides exactly what I needed. Thanks to OP for sharing! Slick and simple

No, how can you not know the difference between RAM and disk in a server context? What sort of programmers are these?

I do wish there was an option to safely disable all connectivity in a browser tab (forever) like with Javascript or camera access. Yes, saving the page, disconnecting your network connection, then deleting the page would work, but it's a real bother.

Also another nitpick: > View the source code It would be really nice if the source code in the browser (no, not the Github repo; how do I know the web server served the same thing as the Github repo?) were displayed in a human-readable format with proper tabbing, comments if applicable, and not an obfuscated, minified form. In fact if your goal isn't specifically obfuscation, it's not necessary to minify JS in genera…

Hm, we could have the best of both worlds if source maps (can already be served to browsers and are supported fine) could be proven authentic.

I believe right now, I could use foo.min.js and serve you a cruddy foo.min.map.js to mislead you.

If I served you the original sources foo.concat.js and a build script to go from foo.concat.js => foo.min.js instead, we could have both the speed of the minified version and the (proven by the browser) accurate source code and maps!
