Introduction¶ ↑

Tokyo Cabinet binding for Node.js. So far only implemented interfaces defined in tokyocabinet.idl.

Install¶ ↑

• Install node.js <github.com/ry/node>

• Install Tokyo Cabinet <1978th.net/tokyocabinet/>

• Download node-tokyocabinet and do;

$ node-waf configure build

Warning¶ ↑

THIS SOFTWARE IS STILL AN ALPHA VERSION.

Sync vs. Async¶ ↑

Sync interface (not recommended because we are using Node.js!).

var hdb = new HDB;
// open database
var success = hdb.open('casket.tch', HDB.OWRITER | HDB.OCREAT);
if (!success) throw hdb.errmsg();
// store a value
var success = hdb.put('foo', 'bar');
if (!success) throw hdb.errmsg();
// retrieve a value
var v = hdb.get('foo'); // => 'bar'
if (v === null) throw hdb.errmsg();
sys.puts(v);

Async interface.

var hdb = new HDB;
// 'setmutex' makes database multi-thread safe
hdb.setmutex();
// open database
hdb.openAsync('casket.tch', HDB.OWRITER | HDB.OCREAT, function(err){
  if (err) throw hdb.errmsg(err);
  // store a value
  hdb.putAsync('foo', 'bar', function(err){
    if (err) throw hdb.errmsg(err);
    // retrieve a value
    hdb.get('foo', function(err, val){
      if (err) throw hdb.errmsg(err);
      sys.puts(val);
    });
  });
});
hdb.put('foo', 'bar');
var v = hdb.get('foo'); // => 'bar'

As you can see, it’s very cumbersome to write with Async APIs. I’m planning to write the Async wrapper API to make it easy to use. Or you can wrap with your preferred library (Promise, Deferred, Do, etc.)

ToDo¶ ↑

• Write async wrapper.

• More tests.
