Proxying Node apps with Charles

Setting up Charles to monitor outgoing Node app requests

• Add global-tunnel-ng module and add something like

// Enable the proxy for outgoing http requests made by this server (dev only)
if (process.env.APP_ENV === 'development' && process.env.http_proxy) {
  console.warn('http_proxy env variable is set, all outgoing requests will be proxied');
 globalTunnel.initialize();
