CouchDB is great. It’s simple interface means all you need to use it is an HTTP client. cURL, for example, works great. I was running into the problem, though, of having to revisit the CouchDB reference and the cURL reference to recall the basic commands.
I was going to write up a quick reference with a bunch of common cURL commands, but Tim Huegdon has already posted a great blog entry so rather than reinvent the wheel, here’s a link!
