couchdb-sync

It's an ugly module, needs lot of a refactoring, i mainly ported @dominictarr's [level-couch-sync][lcs] to a general sync module.

I did this because I'm trying to replicate npmjs registry to riak.

API

var sync = require("couchdb-sync")("https://fullfatdb.npmjs.com/registry");
sync
  .on( "data", function( doc ){
    // doc is a couchdb doc
  })
  .on( "progress", function( progress ){
    // progress of replication
  })
  .on( "fail", function( err ){
    // ohhh uhhh npm is down?!:D
  });

It emits data and progress events, and you can even pause and resume syncing by calling instance.feed.pause() and instance.feed.resume() methods. (It can be useful if data comes too fast).
