# Project Anatomy: vps-manager

## Purpose
Single-page VPS fleet tracker — add/edit/delete servers with specs, IPs, cost, status.

## Files
- `vps_manager.html` — full UI (vanilla JS, IBM Plex font, dark GitHub-style theme)
- `server.js` — Express server; serves static files + REST API; binds 0.0.0.0:8080
- `package.json` — express ^4.18.2 dependency
- `start.bat` — double-click launcher for Windows
- `data/servers.json` — persistent JSON storage (auto-created on first run)
- `node_modules/` — npm dependencies

## API
- GET  /api/servers       → array of server objects
- POST /api/servers       → upsert server (id present = update, absent = create)
- DELETE /api/servers/:id → remove server
