node-riak - an client library for Riak
// intialize client
var db = new Riak.Client({
host: 'localhost',
port: 8098,
});
// store nyarlathotep in deities as plain text with an 'r' value of 1, and
// return the content again (content is not returned by default)
db.store('deities', 'nyarlathotep', "The crawling chaos", { returnbody: 1, r: 1 })
.addCallback(function (resp, statusCode) {
// ...
});
// store cthulhu as binary and update the vclock
db.store('deities', 'cthulhu',
{ type: 'binary', headers: { 'x-riak-vclock': '...' })
.addCallback(function (resp, statusCode) {
// ...
});
// fetch azathoth from deities
db.fetch('deities', 'azathoth')
.addCallback(function (resp, statusCode) {
sys.debug(inspect(resp.headers));
sys.debug(inspect(resp.data));
var vclock = resp.headers['x-riak-vclock'];
});
// Errback fired if there was an error
db.fetch('deities', 'yog-sothoth')
.addErrback(function (data, statusCode) {
if (statusCode == 404 ) { ... }
}
A basic wrapper around Node's HTTP facilities for communicating with a Riak server's "raw" HTTP interface.
The client methods fetch, store, and remove return promises which fire
when the Riak server responds to the request. The success callback is called
with two arguments: an object with properties header and data; and an
integer HTTP response status code.
If the content-type of the response is application/json the data property
will be the parsed JSON object.
If the HTTP response code isn't in the 2XX range an errback will be fired instead of a promise. It will have the same arguments as described in the success case above.
By default the node-riak tests run on localhost:8098 on the node-riak-test-pots
