Any plans to add NPM?

any plans to add the tool npm to hass.io so people can install addons to homebridge fromnpmjs.com

This is not something that Hass.io should do. Instead it’s something that the Homebridge add-on should do. And since homebridge uses Node I’m pretty sure npm is already installed.

I haw homebridge add-on installed but when I login to hass.io and write command npm it respons
1026bd88dbdb:~# npm
-ash: npm: not found
1026bd88dbdb:~#

do hass add-ons run in a sandbox?

They do indeed. We use docker. The addon author defines what is available inside their sandbox
