Error: not supported

[kirbysayshi]

No matter what I do I seem to always receive the following error when using multilevel:

/Users/drewp/Dropbox/js/dataminer/node_modules/multilevel/lib/client.js:107
  if (allowed.indexOf(ev) == -1) throw new Error('not supported');
                                 ^

Relevant code:

// digger.js
var path = require('path');
var net = require('net');
var level = require('level');
var multilevel = require('multilevel/msgpack');
var LevelLiveStream = require('level-live-stream');

var dbpath = path.join(__dirname, path.basename(__filename, '.js') + '.db');
var db = level(dbpath, {
  createIfMissing: true,
  valueEncoding: 'json'
});

LevelLiveStream.install(db);

net.createServer(con => {
  con
    .pipe(multilevel.server(db))
    .pipe(con);
}).listen(3000);

multilevel.writeManifest(db, __dirname + '/manifest.json');

// ...code that puts a bunch
db.put( 'twitter:' + tweet.id_str, { tweet: tweet, sentiment: 0 });

// miner.js
var path = require('path');
var net = require('net');
var multilevel = require('multilevel/msgpack');
var LevelLiveStream = require('level-live-stream');

var manifest = require('./manifest.json');

var db = multilevel.client(manifest);
var con = net.connect(3000);

LevelLiveStream.install(db);

con
  .pipe(db.createRpcStream())
  .pipe(con);

db.createLiveStream().on('data', console.log.bind(console));

And I've verified that my manifest.json loads and does have createLiveStream/liveStream added to it.

Also tried without the manifest and still got the same error.

Relevant packages:

$ npm ls | grep level

Please let me know if there are any more details I can provide!

you don't need to install it on the client - just install it on the server before you connect generate the manifest

@dominictarr oh.

Eeesh sorry for not understanding that.

Thanks for your help!
