###In App database usage Install node modules

npm install levelup

import js.Node.*;
import js.node.LevelUP.LevelUPInstance.*;
import js.node.LevelUP;

class Main {
	static function main() {
		var db = levelup(__dirname + "/db", function(error : LevelUPError, db : LevelUP) {
			if (error != null) throw error;
			
			db.put("key", "value", function(error : LevelUPError) {
				if (error != null) throw error;
				
				db.get("key", function(error : LevelUPError, value : String) {
					if (error != null) throw error;
					
					trace('$value should equal "value"');
				});				
			});
		});	
	}
}
	

##Client / Server usage ###Database server Install node modules

npm install levelup
npm install multilevel

import js.node.LevelUP.LevelUPInstance.*;
import js.node.Multilevel.MultilevelInstance.*;
import js.Node;
import js.Node.*;

class MainDatabaseServer{
	public static function main() {
		var db = levelup(__dirname + "/db");
		net.createServer(function (c:Dynamic) {
			c.pipe(multilevel.server(db)).pipe(c);
		}).listen(3000);
	}
}

###Database client Install node modules

npm install multilevel

import js.Node.*;
import js.node.LevelUP;
import js.node.Multilevel.MultilevelInstance.*;

class MainDatabaseClient{
	public static function main() {
		var db = multilevel.client();
		con = net.connect(3000, "127.0.0.1");
		db.pipe(con).pipe(db);

		db.put("key", "value", function(error : LevelUPError) {
			if (error != null) throw error;
			
			db.get("key", function(error : LevelUPError, value : String) {
				if (error != null) throw error;
				
				trace('$value should equal "value"');
				con.destroy();
			});				
		});
	}
}

Important considerations

LevelDB does not yet work on Windows. You can however use Multilevel on Windows to connect to a LevelDB instance running on a supported platform. This can be a VM running on Windows.
