vefaas: Volcengine FaaS CLI

vefaas is the command-line tool for Volcengine Function Service (veFaaS). It enables serverless application deployment, function management, and configuration through a streamlined workflow.

Installation

npm i -g https://vefaas-cli.tos-cn-beijing.volces.com/volcengine-vefaas-latest.tgz

Core Workflow

The typical deployment pattern:

Check Node.js: node --version (requires >= 18, recommended 20+)
- If version is too low, switch using nvm (nvm use 20) or fnm (fnm use 20), or manually install a newer version
Check CLI: vefaas --version to verify installation
Check Auth: vefaas login --check to verify login status
- If not logged in, run vefaas login --sso (opens browser, auto-completes when user authorizes - no manual input needed)
Deploy: vefaas deploy --newApp --gatewayName $(vefaas run listgateways --first) --yes
Access: vefaas domains to view URLs
