Connect to Postgres/Redshift over Socks proxy.

client.js

var pg = require('pg'),
    url = require('url'),
    SocksConnection = require('socksjs');

var db = url.parse(process.env.REDSHIFT_CONN_STRING),
    dbAuth = db.auth,
    dbUsername = dbAuth.split(':')[0],
    dbPassword = dbAuth.split(':')[1],
    dbName = db.pathname.replace('/', '');

var proxy = url.parse(process.env.QUOTAGUARDSTATIC_URL),
    auth = proxy.auth,
    username = auth.split(':')[0],
    pass = auth.split(':')[1];

var sock_options = {
    host: proxy.hostname,
    port: 1080,
    user: username,
    pass: pass
};

var remote_options = {
    host: db.hostname,
    port: db.port
};

var sockConn = new SocksConnection(remote_options, sock_options);

var config = {
    user: dbUsername,
    database: dbName,
    password: dbPassword,
    stream: sockConn
};

var client = new pg.Client(config);

// connect to our database
client.connect(function (err) {
  if (err) throw err;

  // execute a query on our database
  client.query('SELECT $1::text as name', ['john doe'], function (err, result) {
    if (err) throw err;

    // just print the result to the console
    console.log(result.rows[0]); // outputs: { name: 'apiary' }

    // disconnect the client
    client.end(function (err) {
      if (err) throw err;
    });
  });
});

I'm curious, where that stream option comes from?

Hi,

can you pls explain how to form process.env.REDSHIFT_CONN_STRING for node js app

As you see using https://nodejs.org/docs/latest/api/url.html for example postgres://user:password@hostname.com nothing special

Hi,

Thanks for reply

I am connecting to aws redshift db and I use Env variable like PGSSLMODE=require and that solved the connectivity issue.

By the way I am using "pg" NPM package for redshift in my Node app and my co-workers think that the client machine must have JAVA runtime or some JDBC/ODBC driver on the computer where Node app is running. Pleases let me know if that is right.

Not sure about that. I don't use java for long time. node-pg using C++ bindings.
