roy-replicator

Node implementation of the CouchDB replication protocol.

Usage

var adapter = require('roy-request');
var roy = require('roy-replicator');
 
roy.replicate({
  source: adapter('http://localhost:5984/my-source'),
  target: adapter('http://localhost:5984/my-target')
}, function(err, resp) {
  // Oh Pris!
});

This should also be possible (but I haven't tested yet):

var adapter = require('pouchdb');

Goals

• Gain deeper understanding of CouchDB replication
• Good readability and testability
• CouchDB replicator compatibility
• Be nearly as fast as CouchDB
• Small browserified footprint
• PouchDB compatibility (replace roy-request with pouchdb)

Resources

• CouchDB Replication Protocol by Alexander Shorin
• Jens Alfkes description of the replication algorithm
• CouchDB Replication Protocol on Data Protocols
• RCouchs Replication Algorithm in pseudo code

Development

• Lint the code with npm run jshint
• Run the tests with npm test
• Browserify with npm run build
• List TODOS with npm run todos
• Run performance tests with npm run perf
