When developing functions using the Node.js runtime in veFaaS, you need to follow the Node.js runtime specifications described by Volcano Engine veFaaS.

Runtime environment

The Node.js runtime versions currently supported by veFaaS are listed below. You can select the desired runtime environment when creating a function.

Node.js 14.x

Node.js 20.x

tip

To use a different Node.js version, deploy an image built on a specific Native runtime: include the runtime for your development language in a Dockerfile, build an image from the file, and then deploy the image.

Filesystem restrictions

Write operations are only permitted in the /tmp directory within the container. The default temporary storage capacity is 512 MiB. If the capacity limit is exceeded, the service will be evicted and restarted.

tip

Local user data written to disk is not persistent. Data will be deleted when the container is destroyed. Proceed with caution. For persistent storage, see Selecting storage for functions.
