qrencode -t utf8 'WIFI:T:WPA;S:network;P:password;;'

Did you type this in from memory?!

In fairness, the string doesn't seem insaneo: T:=Type S:=SSID P:=Password then only the leading and trailing chars need to be "remembered", plus whatever the escape character is for that password string (or maybe even the SSID -- I'm not super clear on what characters can be in an SSID)

Just like perl and grep, I stick to make because it's likely to be already available everywhere I need it. Such is the tyranny of the installed base. :/

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?

I can't speak for the poster, but sometimes the fun is in using tools you know. I don't know VanillaJS that well, so I took a stab at the same concept: https://q726kbxun.github.io/qrcodes/ Not nearly as pretty, since I know even less about making pages pretty, but still, a fun little stab at making such a site.

I'd say that a tiny amount of CSS would make that basically perfect for the task, except that it's honestly already perfect for the task now. Though it looks like you replace semicolon a second time instead of colon in clean.

wow ok, so you expect me to have a computer (?!) with:

    - a keyboard?
    - access to a terminal??!?!?!
    - ability to install qrencode???
    - knowledge of copy and paste!?!?!
    - some way to edit the command you posted to my specific username and password?!

franky this is ridiculous when i could just make a repo that uses make, docker, yarn, npx, nginx, react, and jest

No password on my farm. Why bother setting a password in a non-crowded area?

Depending on how remote your farm is and how strong is the WiFi signal outside your premises (from a nearby public road, ..).

Average case you are in the middle of bumfuck nowhere with a huge private property surrounding your WiFi and nothing's gonna happen.

Worse case some script kiddie attacks your vulnerable router (if using default password) or a smart gadget (if you have some and it's a couple of years old) to join a botnet and get your IP address on a blacklist limiting your internet usability (blacklisted IPs may not be able to send e-mails, may get captchas on major websites like Google, ...)

Worst case someone driving around noticing you have an open WiFi may drop a battery/solar powered raspberry pi with a 4G modem nearby your WiFi and use your WiFi as an untraceable VPN/proxy to perform some illegal stuff (e.g. upload child pornography or perform some serious hacking) and getting you in trouble with the law.

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?

This is for public encrypted guest WiFi networks, to make guests lives more comfortable... you can scan this with your phone to automatically connect without needing to type the password which can come handy if the password is at least somewhat secure.

Usually it's printed in the same places where you would actually print your plaintext Wi-Fi password, if you're already doing that, for example in restaurants (e.g. QR code inside a menu card that's only given to actual customers), offices (QR code inside meeting room for actual guests), airbnbs (QR code on a fridge inside your house), hotels (QR code inside the room with a router))

This is a nice idea! I once whipped up a shell script to do the same thing. UX feedback - disable autocorrections on the input fields [1], you may want to trim white space as well. [1] https://davidwalsh.name/disable-autocorrect

Please don’t trim whitespace, I ended up on a network recently which had a space on the end of the SSID

I hope you told them to fix their shit.

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.

DevTools -> network -> Change the throttling to "offline"

Offline is not an option in Firefox, just progressively worse connection options.

Why would you trust a random page on the internet and go paste your wifi password on it?

opening in incognito tab with internet disconnected to make sure it works offline and that nothing gets sent after you close the incognito tab should be safe & secure but yeah you can also google the proper qr code format and make it yourself using qrencode in terminal or something like that...

but for semi-public WiFis like the ones in restaurants, hotels, ... it's a survivable risk
