MongoDB database adapter for livedb

livedb-mongo

MongoDB database adapter for livedb. This driver can be used both as a snapshot store and oplog.

Snapshots are stored where you'd expect (the named collection with _id=docName). Operations are stored in COLLECTION_ops. If you have a users collection, the operations are stored in users_ops. If you have a document called fred, operations will be stored in documents called fred v0, fred v1, fred v2 and so on.

JSON document snapshots in livedb-mongo are unwrapped so you can use mongo queries directly against JSON documents. (They just have some extra fields in the form of _v and _type). You should always use livedb to edit documents - don't just edit them directly in mongo. You'll get weird behaviour if you do.

Usage

LiveDB-mongo wraps mongoskin. It passes all the arguments straight to mongoskin's constructor. npm install livedb-mongo then create your database wrapper using the same arguments you would pass to mongoskin:

var livedbmongo = require('livedb-mongo');
var mongo = livedbmongo('localhost:27017/test?auto_reconnect', {safe:true});

var livedb = require('livedb').client(mongo); // Or whatever. See livedb's docs.

If you prefer, you can instead create a mongoskin instance yourself and pass it to livedb-mongo:

var mongoskin = require('mongoskin');
var skin = mongoskin('localhost:27017/test?auto_reconnect', {safe:true});

var livedbmongo = require('livedb-mongo');
var mongo = livedbmongo(skin);
