A first program in golang, with a short aside about Google

Share

I have reached the point in my life where I needed to write my first program in golang. I pondered for a disturbingly long time what exactly to write, but then it came to me…

Back in the day Google had an internal short URL service (think bit.ly, but for internal things). It was called “go” and lived at http://go. So what should I write as my first golang program? go of course.

The implementation is on github, and I am sure it isn’t perfect. Remember, it was a learning exercise. I mostly learned that golang syntax is a bit bonkers, and that etcd hates me.

This code stores short URLs in etcd, and redirects you to the right place if it knows about the short code you used. If you just ask for the root URL, you get a list of the currently defined short codes, as well as a form to create new ones. Not bad for a few hours hacking I think.
