multilevel and sublevel working

client.js

var multilevel = require('multilevel');
var net = require('net');
var after = require('after');
var Sublevel = require('level-sublevel');

var manifest = require('./manifest.json');
var db = multilevel.client(manifest);
var con = net.connect(3000);
con.pipe(db.createRpcStream()).pipe(con);

// not sure if this is correct.. ?
var stuffDb = db.sublevel('stuff');
var preDb = db.sublevel('pre');

preDb.put('heyyy', { value: 'there' }, function(err) {
  // the pre hook should be executed on the server, shouldn't it?
  
  if (err) { throw err; }
});

server.js

var multilevel = require('multilevel');
var net = require('net');
var level = require('level');
var Sublevel = require('level-sublevel');
var port = 3000;

var db = Sublevel(level(__dirname + '/mydb', { valueEncoding: 'json' }));

// so I want to use these 2 sublevels on the client
var stuff = db.sublevel('stuff');
var preDb = db.sublevel('pre');


preDb.pre(function (ch, add) {
  console.log('OK this should be called once');
});

// now write the manifest to a file
multilevel.writeManifest(db, __dirname + '/manifest.json');

net.createServer(function (con) {
  con.on('data', function(data) {
    // console.log(data.toString());
    // console.log('------------------------------');
  });
  con.pipe(multilevel.server(db)).pipe(con);
}).listen(port);
console.log('Multilevel server started on port %s', port);
