diffsync-couchdb v1.0.0

A CouchDB data adapter for diffsync

diffsync-CouchDB

A CouchDB data adapter for diffsync

Usage

The CouchDB adapter needs a reference to a database object to write to. This database object is expected to have a cradle-like interface. For reading, it uses get(id, callback) and for writing it uses save(id, doc._rev, data, callback).

  var CouchDBDataAdapter = require('diffsync-couchdb'),
      cradle             = require('cradle'),
      diffsync           = require('diffsync'),

      couchDbAdapter, database, server;

  // set up your CouchDB driver (cradle or cradle-compatible)
  // (...)

  // create a database object
  database = (new cradle.Connection()).database(databaseName)

  // pass it on to the adapter
  couchDbAdapter = new CouchDBDataAdapter(database);

  // pass the adapter to diffsync
  server = new diffsync.Server(couchDbAdapter, socketIO);

This adapter assumes that while a document is being edited with diffsync, there is no other manipulating it. Which means, this adapter always overrides the latest version from your database with the latest version from diffsync.
