Accessing a Postgres/Redshift Database via a Static IP from Node.js
You can route all database traffic via a Static IP in Node.js using XLRoutes.
Currently there is a limitation in that you can’t use the built in connection pooling so this is not recommended for high traffic applications.
This example provided by Ladislav Prskavec.
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.xlroutesSTATIC_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;
});
});
});
We have examples for other common scenarios as well, but if you can’t find what you are looking for just send us a Support ticket and we’ll get one sent to you.
