It’s been a while since I released something new. This time around I wrote a tiny thing called Watcher, which’ll execute command whenever the file system changes. I didn’t even bother to publish it on npm since it’s totally tailored towards me. You can easily enough install it by running the following:

npm install --global gummesson/watcher

It’s mostly useful when you don’t need a fully fledged build system but want to run an arbitrary command. It should work well enough on all operating systems, although I haven’t tested it on a Mac yet.
