A CouchDB data adapter for diffsync
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.
