This is a complete rewrite from the 0.0.x releases to significantly
increase speed, stability and consistency. All sample applications have
been rewritten and an API reference has been built to accompany this
release. Additionally, the API itself has been refactored to provide a
much more consistent experience.
The new API puts a few new arguments in front of the developer, we think
it’s not too obtrusive and makes for a much more uniform interface when
building apps that handle responses. For example, in 0.12.x you would have
done:
bucket.get( [‘a’, ‘b’], function(err, vals, metas) {
console.log(vals[‘a’], metas[‘a’].cas);
});
And now that’s:
bucket.multiGet( [‘a’, ‘b’], function(err, results) {
console.log(results[‘a’].value, results[‘a’].cas);
});
If you’ve used this before, you’ll note that the constructor has changed
slightly as well. Additionally, you can now begin executing operations
against the bucket before it has successfully connected and the operations
will be queued until successful connection or a critical error occurs.
Before:
couchbase.connect( options, function(err, bucket) {
… handle any errors
bucket.get( … );
});
now is:
var bucket = new couchbase.Connection(options, function(err) {
… handle any errors
bucket.get( … );
});
or even:
var bucket = new couchbase.Connection(options, function(err) {
... handle any errors
});
bucket.get( … );

On performance, this all uses libcouchbase underneath and we’ve made
changes to libcouchbase to work nicely with libuv. Between that and some
other changes, our tests are showing great performance!
We would like to work quickly toward a 1.0 release. How quickly we get
there depends in part on feedback we receive! We’d love to get your
feedback.
Brett.
