Follow DB Updates

CouchDB 1.4.0 introduced the _db_updates endpoint for watching for created and deleted databases. This module makes it easy to consume this endpoint, and provides a poll based pollyfill for older versions of CouchDB


npm install follow-db-updates


var DBUpdates = require('follow-db-updates');
var changes = new DBUpdates('http://admin:pass@localhost:5984');

changes.on('init', function(db_list){
    // on init we provide a list of all the current databases

changes.on('data', function(change){
    console.log(change); // change is one of the following
                         // { type: 'created', db_name: 'aaaaa' }
                         // { type: 'deleted', db_name: 'aaaaa' }
