I can also recommend drawing it instead of printing if you hate printers with the same passion as me. Record to beat for drawing a working QR code is 3 tries and I think about three hours (for an SSID of 13 bytes (5 unicode characters) and 19-character password). I did it mostly out of curiosity how hard it would actually be (spoiler: medium difficulty).

A remedy exists, it costs around 100€, is sold by Brother and is called "wifi-enabled laser printer". Your life will be free off printing woes onwards.

Asking as a person who understands the fundamentals of all of the technologies involved but is horrified by much of what goes on in the minds of today's web developers and designers, what motivates the decision to make this repo use make, docker, yarn, npx, nginx, react, and jest rather than a bit of static HTML and css and something like qrjs2.js or VanillaQR.js with a simple canvas or datauri update in onInput?

Probably to learn those various technologies. Not only did they use a bunch of new tech, they made something other people can use in the process. Better than making a bunch of throwaway code.

Of course, why write 50 lines of throwaway code when you can write 500?

Single static HTML files are under valued.

I am sure that this is not what this site is for. But... For a moment I thought: What a great attack vector. Collect WiFi passwords from around the globe.

No better than obfuscated JavaScript to give trust to the average HN reader.

You just send false info first.

Well, maybe the site sends all the passwords when you close the tab. The point is not to get used to entering passwords to third party websites.

"Tape it to the fridge" Please don't do this, at least keep it hidden from general viewing.

By generating the QR code locally via JS. You can check the source code https://github.com/bndw/wifi-card/blob/master/package.json#L...

I’m not sure what you think I was asking the previous commenter. This makes no sense as a reply.

But... that's exactly what it does though?

If OPs experience is anything like mine, they just suck at doing their job. There's often some silly reason its stuck, or it prints wrong, or the colors are off, etc, its really just a super painful experience and I can't believe its still so bad.

Is this some meme I didn't hear about?

This looks like a simple WiFi password generator, a cooler solution would be to generate one-time passwords for guests. When someone comes to you, they can click on the touch display to generate a password, each guest can then have a separate VLAN.

That's a bit more elaborate, but with WPA enterprise, a radius server and a web-ui this should be pretty doable

> Your WiFi information is never sent to the server.

This makes me think that we could use some flag that identifies purely static websites. Like next to the green https lock there is a sign that this website can not send data to any server
