Azure Functions support for Node 12 is ending on 13 December 2022

Published date: October 10, 2022

Node 12 is only supported by Azure Functions host version 3, which is ending support on 13 December 2022. Node 12 also reached the end of community support 30 April 2022.  

As such, we recommend developers to update their functions apps to use Azure Functions host version 4 and Node 16. The Functions service will continue to run applications that are running Node 12 beyond 13 December 2022, but customers will be asked to upgrade to Node 16 if they need support.  

Required action 
To avoid potential service disruption and security vulnerabilities in your applications, update your Functions applications to use runtime version 4.x and Node 16 before 13 December 2022.
