19NOTE: you must use the framed thrift transport, TFramedTransport in most
20implementations, on the server side. Using a popular example, this is enabled
21by default in Cassandra 0.7 (but configuration must be changed in Cassandra
220.6.x and earlier).
23
24## Install
25
26 npm install thrift
27
28## Thrift Compiler
29
30You can compile nodejs sources by running the following:
31
32 thrift --gen js:node thrift_file
33
34## Cassandra Client Example:
35
36Here is a Cassandra example:
37
38 var thrift = require('thrift'),
39 Cassandra = require('./gen-nodejs/Cassandra')
40 ttypes = require('./gen-nodejs/cassandra_types');
41
42 var connection = thrift.createConnection("localhost", 9160),
43 client = thrift.createClient(Cassandra, connection);
44
45 connection.on('error', function(err) {
46 console.error(err);
47 });
48
49 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) {
50 if (err) {
51 // handle err
52 } else {
53 // data == [ttypes.ColumnOrSuperColumn, ...]
54 }
55 connection.end();
56 });

59## Int64
60
61Since JavaScript represents all numbers as doubles, int64 values cannot be accurately represented naturally. To solve this, int64 values in responses will be wrapped with Thirft.Int64 objects. The Int64 implementation used is [broofa/node-int64](https://github.com/broofa/node-int64).
