Building my npx business card

Ooh, free real estate, let's colonize and gentrify package management
aabhay•1y ago
Lmao, gentrify cracked me up

Do these npx business cards run arbitrary code on your computer?
cypherpunks01•1y ago
npx

Run a command from a local or remote npm package

Description

This command allows you to run an arbitrary command from an npm package (either one installed locally, or fetched remotely), in a similar context as running it via npm run.

neilv•1y ago
Yes, then is a "command from an npm package" arbitrary code?

And what is this "similar context as running it via npm run"?

Would it be better to answer the question directly?

joshka•1y ago
Yeah, this seems like a very smart but inherently flawed idea.
cypherpunks01•1y ago
Yes I agree! OSS package management ecosystems are a great idea, but allowing submissions without any review or vetting is just asking for supply chain attacks.
Xss3•1y ago
May as well just release an executable tbh.

Reminds me of JAPH [0] - a tiny Perl program that was used in email/newsgroup signature to give it personal touch.

Terminal business cards are a nice idea, but RCE business cards are just asking for trouble. Instead of npx, what happened to good'ol curl? Something like

$ curl ashley.dev

Some decades ago, we had finger (https://en.wikipedia.org/wiki/Finger_%28protocol%29) which is designed for this very use case. Sadly it's no longer installed by default with most distros:

$ finger @ashley.dev

This would be a great advertisement for security consulting.
