The easiest way to set this up is to wire two inject nodes as the ngrok node's input, one with the payload of the string on and the other with off. The ngrok node takes the strings on or off as input to start/stop the tunnel, and outputs the ngrok host address as the msg.payload. Image showing managing the palette in NodeRed After restarting your editor, the ngrok node should appear in the node palette. To do so, open up Manage palette from the hamburger menu in your Node-RED editor, search for the node-red-contrib-ngrok package and click install.

Install the node-red-contrib-ngrok Packageįirst, you'll need to install the ngrok node. In case you'd rather not leave your Node-RED editor, you could use the ngrok node for the same functionality.Īfter you specify the port that Node-RED listens on (usually 1880), the ngrok client initiates a secure connection to the ngrok server and then anyone can make requests to your local server through the ngrok tunnel address.īy running this node, you will be exposing your Node-RED install to the public internet, therefore you are strongly advised to set an admin password on the editor. Read Aaron's blog post to find out more about this option.Īn image showing the output of an ngrok tunnel in the Terminal

Also, re-deploying your code every couple of minutes while debugging might get slightly frustrating.Įxposing your local server to the internet with ngrok only takes one command in your terminal, once you've installed it on your local machine. Although using these kinds of services is getting easier all the time, there's usually some cost and time commitment involved. By default, it creates both HTTP and HTTPS endpoints, making it useful for testing integrations with third-party services or APIs that require valid SSL/TLS domains.Īnother option would be deploying your code to a remote server. Ngrok is a cross-platform application that exposes your local server to a unique ngrok.io subdomain over secure tunnels.

If you're developing on localhost, this is where Ngrok comes into play. Without exposing your server to the internet, there is no way of receiving messages on your webhooks. When building webhook consumers, you need a publicly accessible URL to configure the API service with. That's great! They are a perfect way to get notified about events like incoming SMS, delivery receipts and a variety of voice call events.

If you've been getting your feet wet in the world of Nexmo APIs, chances are that you've come across webhooks.
