🔄 Ephemeral Runner — vforge run
The ephemeral runner is VelociForge's flagship feature — it mounts node_modules as a zero-copy virtual symlink, runs your command, and then unmounts and cleans up automatically when the process exits.
⚡ How It Works
vforge run npm start
│
▼
1. Pre-flight (0.70ms)
→ Reads .vforge.json fingerprint
→ If global cache hit: mount symlink (1.45ms) — no extraction needed
→ If cold start: extract to ~/.velociforge/cache/<hash>, then symlink
│

2. Spawn Process
→ node_modules/.bin injected into PATH
→ Your server starts as normal
│
▼
3. Post-flight Cleanup (2.09ms)
→ Dependencies unchanged? Skip re-pack.
→ Unmount symlink / remove node_modules
→ Zero disk footprint restored🚀 Usage
bash
# Run any npm script
vforge run npm start
vforge run npm run dev
vforge run npm test
# Run any Node.js command directly
vforge run node server.js
vforge run tsx server.ts🧠 Smart Dirty Detection
VelociForge tracks the package.json and lockfile SHA-256 fingerprint during the session.
- If dependencies were not changed during the run → skips re-packing.
- If dependencies were modified → automatically re-packs to a fresh
.vforgearchive before cleanup.
