Objective
This article shows you where to see the Node.js version a Functions service runs on and how Twilio warns you when that version is being retired, so you can plan an upgrade before your functions are affected.
Product
Twilio Functions and Assets
Environment
Twilio Console
Procedure
- In the Twilio Console, select Builder tools in the left sidebar.
- Select Functions & Assets, then Services.
- Select the name of the service you want to check.
- Select the Dependencies tab.
- Read the Node.js version field. It shows the version your functions run on.
Additional Information
- The currently available versions are Node.js v22 and Node.js v24. New services use Node.js v22 by default.
- If the service runs on a version that is being retired, a warning appears at the top of the editor naming that version, along with a View upgrade guide link to the upgrade instructions. The retiring version also stays listed in the Node.js version field so you can see what the service is on today.
