node version 6 or later is required
npm install thrift
You can compile IDL sources for Node.js with the following command:
thrift --gen js:node thrift_file
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(); }); ```
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.
Several example clients and servers are included in the thrift/lib/nodejs/examples folder and the cross language tutorial thrift/tutorial/nodejs folder.
You can use code generated with js:node on browsers with Webpack. Here is an example.
thrift –gen js:node,ts,es6,with_ns
```javascript import * as thrift from ‘thrift’; import { MyServiceClient } from ‘../gen-nodejs/MyService’;
let host = window.location.hostname; let port = 443; let opts = { transport: thrift.TBufferedTransport, protocol: thrift.TJSONProtocol, headers: { ‘Content-Type’: ‘application/vnd.apache.thrift.json’, }, https: true, path: ‘/url/path’, useCORS: true, };
let connection = thrift.createXHRConnection(host, port, opts); let thriftClient = thrift.createXHRClient(MyServiceClient, connection);
connection.on(‘error’, (err) => { console.error(err); });
thriftClient.myService(param) .then((result) => { console.log(result); }) .catch((err) => { …. }); ```
Bundlers, like webpack, will use thrift/browser.js by default because of the
"browser": "./lib/nodejs/lib/thrift/browser.js" field in package.json.
```javascript import thrift from ‘thrift’; import { MyServiceClient } from ‘../gen-nodejs/MyService’;
const host = window.location.hostname; const port = 9090; const opts = { transport: thrift.TBufferedTransport, protocol: thrift.TBinaryProtocol } const connection = thrift.createWSConnection(host, port, opts); connection.open(); const thriftClient = thrift.createWSClient(MyServiceClient, connection);
connection.on(‘error’, (err) => { console.error(err); });
thriftClient.myService(param) .then((result) => { console.log(result); }) .catch((err) => { …. }); ```
