windows-deployment

windows-deployment is a skill for Claude Code, Codex from saajunaid/caddis-plugin. It costs 53 tokens per session (9,357 once invoked), scanned A, original, MIT.

A deployment setup for FastAPI and React/Vite applications on Windows Server. It uses Windows services and IIS or nginx as a reverse proxy, which passes web requests to the application.

In plain words
What is it for?
Use it to configure NSSM services, IIS or nginx routing, development and production settings, and a Git-pull deployment workflow.
Why use it?
It addresses the operating-system-specific work of keeping the frontend and API running, reachable, and updateable on a Windows production server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

windows-deployment scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Windows Server Deployment Skill

Deploy FastAPI + React/Vite web applications to Windows Server using NSSM services, a reverse proxy (IIS or nginx), and a git-pull workflow.

1. When to Apply This Skill

Trigger conditions:

  • "Deploy this app to prod" / "Deploy to Windows Server"
  • Setting up a new web application on a Windows prod server
  • Adding a reverse proxy (IIS or nginx) for an app
  • Registering NSSM services
  • Configuring environment-aware dev/prod code (subpath, auth, static serving)
  • Troubleshooting prod deployment (502, 404, service won't start)
  • "Why can't the frontend reach the API?"

Prerequisites the user should have:

  • A FastAPI + React/Vite app
  • A Windows Server target machine
  • NSSM installed on the target
  • A git remote (Gitea, GitHub, etc.) accessible from both dev and prod
  • Python and Node.js installed on the target

2. Architecture Overview

Two reverse proxy strategies are available. Choose based on what the server already runs.

Strategy A — IIS (Recommended When IIS Is Already Running)

Browser → IIS (:80/:443)
           ├─ Windows Auth + Active Directory (handled by IIS)
           ├─ URL Rewrite: /{subpath}/api/* → http://localhost:{api-port}/api/*
           └─ URL Rewrite: /{subpath}/*     → http://localhost:{api-port}/*
                                                 ├─ /api/* → FastAPI routers
                                                 └─ /*     → FastAPI serves dist/ static files

NSSM manages:
  - <org>-{app}-api-prod (one per app)

Key characteristics:

  • IIS handles authentication (Windows Auth, AD groups) — app code has zero auth logic
  • App is deployed under a subpath (e.g. /my-app/) — IIS strips the prefix before forwarding
  • FastAPI serves both API routes and static frontend files in production
  • No separate frontend service/port needed

Strategy B — nginx (Standalone Reverse Proxy)

Browser → nginx (:51xx) → serves static dist/ files
                         → proxies /api/* → uvicorn (:81xx)

NSSM manages:
  - <org>-nginx-prod (single instance, all apps)
  - <org>-{app}-api-prod (one per app)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
