## Compatibility

node version 6 or later is required

## Install

    npm install thrift 

## Thrift Compiler

You can compile IDL sources for Node.js with the following command:

    thrift --gen js:node thrift_file

## Cassandra Client Example:

Here is a Cassandra example:

```js
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();
});
```

## Int64

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

## Client and server examples

Several example clients and servers are included in the thrift/lib/nodejs/examples folder and the cross language tutorial thrift/tutorial/nodejs folder.
