Error: getaddrinfo ENOTFOUND undefined undefined:5432

See original GitHub issue

var express       = require('express');
var pg            = require('pg');
var CONSTANT      = require('../src/constant.js');
var router = express.Router();
var connectionString = CONSTANT.DB_NAME+'://'+CONSTANT.DB_USERNAME+':'+CONSTANT.DB_PASSWORD+'@'+CONSTANT.DB_URL+':'+CONSTANT.DB_PORT+'/'+CONSTANT.DB_SCHEMA;
var client = new pg.Client(connectionString);
client.connect();

var config = {
  user: CONSTANT.DB_USERNAME,
  database: CONSTANT.DB_SCHEMA,
  host: CONSTANT.DB_HOST,
  password: process.env.PGPASSWORD,
  port: CONSTANT.DB_PORT
};

console.log("config : "+JSON.stringify(config));
var pool = new pg.Pool(config);

pool.on('error', function(error, client) {
  if(err) {
    console.log(err);
  }
})

router.get('/testing', function(req, res, next) {
  console.log("--------------");
})

module.exports = router;

Below is the error am getting

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: getaddrinfo ENOTFOUND undefined undefined:5432
    at errnoException (dns.js:27:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:78:26)

Also this link https://github.com/brianc/node-postgres doesn’t seem to be passing the host/hostname to the config param NodeJS version is 4.4.2… PostgreSQL version is 9.5.2

Looking at the error message undefined:5432 it looks like it is not finding the DB host name.

Hi @brianc… I deleted my node_modules and did npm install again. After that am not getting that error. Assuming its resolved?

Just wanted to confirm with you before I close this thread.

try this

var express       = require('express');
var pg            = require('pg');
var CONSTANT      = require('../src/constant.js');
var router = express.Router();
var config = {
  user: CONSTANT.DB_USERNAME,
  database: CONSTANT.DB_SCHEMA,
  host: CONSTANT.DB_HOST,
  password: process.env.PGPASSWORD,
  port: CONSTANT.DB_PORT
};

console.log("config : "+JSON.stringify(config));
var pool = new pg.Pool(config);
pool.query('SELECT NOW()', function(err, res) {
  if (err) throw err
  console.log(res.rows)
})

router.get('/testing', function(req, res, next) {
  console.log("--------------");
})

module.exports = router;

That should work if you’re using pg>=6.0.0
