Getting started with Erlang

Getting started with Erlang and the CouchDB API.

eCouch

eCouch is an Erlang application that provides an API to a CouchDB server. Code and documentation can be obtained at:

• http://code.google.com/p/ecouch

Characteristics

• Uses the rfc4627 module from LShift

• eCouch design was inspired by the article Building a Non-blocking TCP server using OTP principles

• It assumes that the inets application is running

Features

• Follows all the OTP design principles

• Can run stand-alone with its own supervision tree or be included inside an existing supervision tree

• Guarantees synchronism between calls and their responses

erlcouch

It is quite easy to throw together a quick interface to CouchDB in Erlang using inets or ibrowse because CouchDB API is so easy. On such interface currently exists at:

• http://code.google.com/p/erlcouch/

Documentation can be found as part of the library.

NOTE: erlcouch was discontinued, but picked up and pushed along at http://github.com/bdionne/erl-couch/

erlang_couchdb

Another Erlang library exists as erlang_couchdb. It is actively development and tries to do as little as possible.

There's a branch implementing a transactional layer for it. Scroll down for documentation:
