From the Apache CouchDB docs:
CouchDB also has Fauxton, a native web-based interface built into CouchDB. It provides an interface to the majority of the CouchDB functionality, including the ability to create, update, delete and view documents and configuration parameters.
I’ve already written a blog post for installing CouchDB 2.0 under Rasbian Jessie for Raspberry Pi. I’m updating my instructions for CouchDB 2.1 and Raspbian Stretch (in addition to Jessie). I’m presenting this “how-to” in coolbook form — i.e. just type in the commands as presented and you should end up with a functional CouchDB install. For more background and info, check out my previous blog post.
[UPDATE: 03 April 2018] I have confirmed that my instructions work for CouchDB 2.1.1 and work under Raspbian Stretch on the new Raspberry Pi 3 Model B+.
