val-town-cli（VAL town CLI 命令行）

Val Town CLI

The vt CLI manages Val Town projects locally. Key concepts:

• Val: A serverless function/project hosted on Val Town
• HTTP Val: A val that serves HTTP requests (filename must contain "http", e.g., index.http.tsx)
• Branch: Version control within a val (not git branches)

Quick Reference

Common Workflows

Create and develop a new val

vt create my-api
cd my-api
# Edit files...
vt push
vt browse  # Open in browser

Clone and modify existing val

vt clone username/valName
cd valName
# Edit files...
vt push

Live development with auto-sync

cd my-val
vt watch  # Syncs on every file save

Work on a feature branch

cd my-val
vt checkout -b my-feature
# Make changes...
vt push
vt checkout main

File Naming Conventions

Val Town detects file types by naming patterns:

Example: To create an HTTP API, name the file api.http.ts or index.http.tsx.

vt checkout -b feature # Create new branch
vt branch -D feature   # Delete branch

Logs

vt tail                          # Stream current val's logs
vt tail @user/valName            # Stream specific val
vt tail --print-headers          # Include HTTP headers
vt tail --reverse-logs           # Latest first

Configuration

vt config options                           # List options
vt config set dangerousOperations.confirmation false  # Disable confirmations
vt config ignore                            # Edit global .vtignore

Project Structure

After cloning/creating, a val directory contains:

• .vt/ - Metadata (like.git)
• .vtignore - Files to exclude from sync
• deno.json - Deno LSP configuration
• Source files (.ts, .tsx, etc.)

Tips

• Use vt push --dry-run to preview changes before pushing
• Use vt checkout --dry-run to preview branch switch effects
• HTTP vals require "http" in the filename to be recognized as endpoints
• The vt watch command enables live reloading with the browser companion extension
