Example

welcome.js

var CouchDBClient = require('couchdb-client');
var client = new CouchDBClient({
    host: '127.0.0.1', //The host to connect to
    port: '5984' //The port
});
client.welcome(function (err, data) {
    console.log(err || data); //Hope it is not an error!
});

If all goes to plan we have a welcome message.

Usage

After requiring it, you will get a constructor. Call the constructor with options to get a client.

Documentation

This will be moved to another site eventually.

CouchDBClient([options])

This constructs your client. The options object can have: host: the host to connect to. Default: 127.0.0.1 port: the port to connect to. Default: 5984
