NOTE: you must use the framed thrift transport, TFramedTransport in most implementations, on the server side. Using a popular example, this is enabled by default in Cassandra 0.7 (but configuration must be changed in Cassandra 0.6.x and earlier).

Install

npm install thrift 

Thrift Compiler

You can compile nodejs sources by running the following:

thrift --gen js:node thrift_file

Cassandra Client Example:

Here is a Cassandra example:

var thrift = require('thrift'),
    Cassandra = require('./gen-nodejs/Cassandra')
    ttypes = require('./gen-nodejs/cassandra_types');

var connection = thrift.createConnection("localhost", 9160),
    client = thrift.createClient(Cassandra, connection);

connection.on('error', function(err) {
  console.error(err);
});

client.get_slice("Keyspace", "key", new ttypes.ColumnParent({column_family: "ExampleCF"}), new ttypes.SlicePredicate({slice_range: new ttypes.SliceRange({start: '', finish: ''})}), ttypes.ConsistencyLevel.ONE, function(err, data) {
  if (err) {
    // handle err
  } else {
    // data == [ttypes.ColumnOrSuperColumn, ...]
  }
  connection.end();
});

Custom client and server example

An example based on the one shown on the Thrift front page is included in the examples/ folder.
