BrowserCouch

CouchDB in the browser - persistant, syncing client side storage.

Status

I'm a few weeks away from what I'd call a 'stable' release. Please feel free to fork or suggest improvements, but I'd hold off on using this in a live setting until I can get some issues ironed out.

Thanks,

Example

###GET:

var database = BrowserCouch('foo');
database.onload(function(){
    database.get('bar', function(d){console.log(d)});
});

###SYNC

database.sync('http://localhost:5984/foo', {continuous:true});

###MAP REDUCE

var test_data = [
	{_id : "0", hello : 'world'},
	{_id : "1", chunky : 'monkey'},
	{_id : "2", foo : 'bar'},
	{_id : "3", black : 'hat'},
	{_id : "4", black : 'tea'},
	{_id : "5", words : 'two foo three'},
	{_id : "6", words: 'two'}
];		

var db = BrowserCouch('bar');

db.onload(function(){
	db.put(test_data, function(){});	
});

Some time later ...

var db = BrowserCouch('bar');
db.onload(function(){
	db.view({
		map : function(doc, emit){
			if (doc.words){
				var words = doc.words.split(" ");
    			for (var i = 0; i < words.length; i++)
      				emit(words[i], 1);
      		}		
		},
		reduce : function(keys, values){
			var sum = 0;
    		for (var i = 0; i < values.length; i++)
      			sum += values[i];
    		return sum;
    	},
    	finished : function(view){
    		console.log(view.findRow('two')); // Should emit 2
    	}	
	});
});
