level-sub

minimalist implementation of level-sublevel

why

so you can create sublevels from a multilevel client

how

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

var port = 3000;

// multilevel server
var dbname = __dirname + '/test.db';
var serverdb = level(dbname);
var server = net.createServer(function(con) {
  con.pipe(multilevel.server(serverdb)).pipe(con);
}).listen(port);

// multilevel client
var clientdb = multilevel.client();
var client = net.connect(port);
client.pipe(clientdb.createRpcStream()).pipe(client);
client.on('connect', function() {

  var db = sublevel(clientdb);
  var ws = db.createWriteStream();
  ws.write({ key: 'table', value: 'meta infos' });
  
  var table = db.sublevel('table');
  ws = table.createWriteStream();
  ws.write({ key: 'row1', value: 'row data' });
  ws.write({ key: 'row2', value: 'row data' });
      
  var rs = db.createReadStream();
  rs.on('data', console.log);  // { key: 'table', value: 'meta infos' }

  rs = table.createReadStream();
  rs.on('data', console.log);  // { key: 'row1', value: 'row data' }
                               // { key: 'row2', value: 'row data' }
});

api coverage

minimal for now

• sublevel()
• put()
• get()
• del()
• batch()
• createReadStream()
• createWriteStream()

notes

should produce 100% level-sublevel compatible leveldbs
