Proxy as Code - Dynamically Forward Private Workloads via the Northflank API Client

Northflank is pleased to release new versions of our JS Client (0.3.5) and CLI (0.5.2). In this release, we have added support for programmatic proxy support. It is now easier than ever to connect to multiple TCP and UDP workloads running in a private VPC with Northflank. This enables similar capability as tools such as kubectl forward, kubefwd, and cloudsql-proxy but now via proxy as code.

  • Works with all TCP and UDP traffic
  • Proxy multiple ports per service or addon
  • Bind traffic to local IP addresses
  • Automates local DNS to replicate production endpoints when relevant permissions are enabled
  • Forward as many services and addons as you need with automatic port selection if you have multiple ports are already in use.
  • Inherits existing Northflank RBAC permissions
const forwardingInfo = await apiClient.forwarding.forwardAddon({ projectId, addonId });

const connectionConfig = {
      port: forwardingInfo[0].data?.port,
      host: forwardingInfo[0].data?.address,
      user: process.env.USERNAME,
      password: process.env.PASSWORD,
      database: process.env.DATABASE,

const connection = await mysql.createConnection(connectionConfig);

await connection.connect();

const results = await connection.query("SHOW TABLES;");

await connection.end();

await apiClient.forwarding.stop();
