npm version Build Status

A node Thrift client utilising a pool of service connections and improved error handling/recovery


  • proper Promise support in pool instance con/destruction
  • correct behaviour on "Internal Error", aka, socket misalignment on unhandled server errors
  • better/existent timeout support for: connections, pool checkout, execution
  • builtin retry support using upstream Thrift code
  • faster detection and pruning of dead connections
  • async/await compatibility and other niceties

Example usage

Given a thrift file calculator_service.thrift with contents:

exception OutOfRange {
  1: string message
service CalculatorService {
  i32 add(1:i32 num1, 2:i32 num2) throws (1:OutOfRange out_of_range)

Compile with the thrift command (installable via your package manager):

thrift --gen js:node calculator_service.thrift

This will produce JS definitions for your service, which can then be used to create a client:

const CalculatorService = require('./CalculatorService');
const thriftClient = require('pooled-thrift-client');

// host and port are mandatory see other config options in comments
const host = '', port = 9000;
const client = thriftClient(CalculatorService, { host, port }, { poolOptions: { max: 5 } });

// use the client as you would a regular client, get pooling for free
client.add(1, 2).then(sum => console.log(sum));


Tests use the calculator_service.thrift example service located in spec/support/thrift. A compiled version is committed to this repository; to recompile it, install thrift using your package manager (e.g., brew install thrift), then follow the instructions in the file.

Tests can be run using

npm test
