VIBE CODING SETUP GUIDE
FastAPI + Node.js with OpenClaw on Native Windows (PowerShell 7)
Overview
You’re creating an agent-driven coding environment using OpenClaw. Instead of copying and pasting from web interfaces, you’ll use a Terminal UI (TUI) so ChatGPT 5.3-Codex can work directly inside your workspace.
—
1. ENVIRONMENT SETUP (NATIVE WINDOWS)
Use PowerShell 7 — not Windows PowerShell 5.1.
Install the following:
• Node.js 22
Install the LTS version or run:
nvm install 22
• Python
Make sure Python 3.10 or newer is installed and added to PATH.
• OpenClaw
Run the installer inside PowerShell 7:
iwr -useb [https://openclaw.ai/install.ps1](https://openclaw.ai/install.ps1) | iex

2. ONBOARDING OPENCLAW FOR AGENTIC CODING
You will use the TUI instead of the web interface.
Steps:
• Start onboarding
openclaw onboard –flow quickstart
• Select model
Choose ChatGPT (OpenAI) → 5.3-Codex
• Interaction mode
Select: “Hatch in TUI”
• Security policy
If you want fewer prompts during automation, set:
exec_approval = Low
(Only do this if you understand the risks.)

3. CREATE THE HYBRID FASTAPI + NODE APP
Inside your project folder, tell OpenClaw:
“Create a FastAPI backend on port 5000 and a Node.js runtime script that calls it.”
Python Backend (main.py)
from fastapi import FastAPI
import uvicorn
app = FastAPI()
@app.get(“/”)
async def root():
return {“status”: “Vibe Coding Active”, “engine”: “GPT-5.3-Codex”}
if **name** == “**main**”:
uvicorn.run(app, host=”127.0.0.1″, port=5000)
Node.js Runtime (app.js)
const startVibe = async () => {
const res = await fetch(‘[http://localhost:5000/](http://localhost:5000/)’);
const data = await res.json();
console.log(“Response from FastAPI:”, data);
};
startVibe();

4. RUNNING THE DEV SERVER
Use PowerShell 7:
• Start FastAPI backend
fastapi dev main.py –port 5000
• Run Node.js runtime
node app.js
Tip:
If the TUI disconnects from the gateway, run:
openclaw doctor
This restores the agent connection (“heartbeat”).

If you want, I can also convert this into a **super-minimal cheat sheet** version (like a one-screen quick reference) — which might actually fit your coding workflow better 👍.
