CouchDBEx

This is supposed to be a good couchdb interface for elixir, documented, tested and other things, that's in progress for now, i know there are erlang and elixir clients already, but they are basically dead and not documented very good if at all, although you might also want to look at icouch

Some features implemented:

• Single and mass document insertion/deletion/update
• Subscribing to changes in the database
• Basic and cookie authentification
• Database configuration retreival and setting
• Document finding
• Attachment uploading/retreival/deletion
• Index creation/deletion/listing
• Replication

Documentation can be found here

Usage example

1. Add the dependency in your application's mix.exs

defp deps do
    [
        # ...
        {:couchdb_ex, "~> 0.2.1"},
    ]
end

2. Use it in your application

2.1. Elixir application

First, add the couchdb worker to your supervisor

    children = [
      {CouchDBEx.Worker, [
          hostname: "http://localhost",
          username: "couchdb",
          password: "couchdb",
          auth_method: :cookie # or :basic, if you feel like it
        ]}
    ]

    opts = [strategy: :one_for_one, name: Application.Supervisor]
    Supervisor.start_link(children, opts)

2.2. Phoenix framework application

Find the application.ex which is usually present in hello/lib/hello/ where hello is your project name. Phoenix uses soft-deprecated Supervisor.Spec thus the minor difference in usage.

Then add the couchdb worker to your application module

def start(_type, _args) do
    import Supervisor.Spec

    children = [
        supervisor(HelloWeb.Endpoint, []),
        worker(CouchDBEx.Worker, [[
            hostname: "http://localhost",
            username: "couchdb",
            password: "couchdb",
            auth_method: :cookie # or :basic, if you feel like it
        ]])
    ]
    opts = [strategy: :one_for_one, name: Hello.Supervisor]
    Supervisor.start_link(children, opts)
end

3. You are all set to make DB operations

Now, you can use functions from CouchDBEx

:ok = CouchDBEx.db_create("couchdb-ex-test")

{:ok, doc} = CouchDBEx.document_insert_one(%{test_value: 1}, "couchdb-ex-test")

This library also includes subscribing to database changes with CouchDBEx.changes_sub and _unsub, see respective functions documentation for more
