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();
}

• Make sure to define export NODE_TLS_REJECT_UNAUTHORIZED=0 since Node seems to ignore the Charles root cert
• Define http_proxy and https_proxy in env like normal:

export HTTP_PROXY=http://127.0.0.1:8888
export HTTPS_PROXY=$HTTP_PROXY
export http_proxy=$HTTP_PROXY
export https_proxy=$HTTP_PROXY
