volcengine-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#

bash

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

Verify installation:

bash

vefaas --version

Core Workflow#

The typical deployment pattern:

1. 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

2. Check CLI: vefaas --version to verify installation

3. 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)

4. Deploy: vefaas deploy --newApp <name> --gatewayName $(vefaas run listgateways --first) --yes

5. Access: vefaas domains to view URLs
