How to Install & Integrate SparrowX Shield into Any Server or Webapp

SparrowX Shield is distributed as a self-contained, zero-dependency standalone drop-in middleware file. You do not need to install anything from public npmjs.org. Drop the file into your project, attach 3 lines of middleware, and traffic streams directly to your 3D Global Traffic Mesh Globe!

Select Your Language or Framework:

1Save File in Project

Save sparrowx-shield.js in your server's root folder. No npm packages needed!

2Attach 3 Lines of Code

Import sparrowxShield and call app.use(sparrowxShield()).

3View Live on 3D Globe

Every incoming visitor immediately lights up an animated arc on the 3D globe!

A. The Standalone File (sparrowx-shield.js):

// sparrowx-shield.js - Zero-Dependency Drop-in File
export function sparrowxShield(options = {}) {
  const originIp = options.originIp || "64.29.17.65";
  const siteDomain = options.siteDomain || "sparrowx.net";

  return function (req, res, next) {
    const clientIp =
      (req.headers["x-forwarded-for"] || "").split(",")[0].trim() ||
      req.socket?.remoteAddress ||
      "127.0.0.1";
    const path = req.url || "/";

    // Autonomous WAF Pattern Filter
    const isThreat =
      /(' OR '1'='1|union select|drop table|<script|eval\(|etc\/passwd|\.env|wp-login)/i.test(
        path + JSON.stringify(req.body || {}),
      );

    if (isThreat) {
      if (res.status && res.json) {
        return res.status(403).json({ error: "Blocked by SparrowX Edge WAF", clientIp });
      }
      res.writeHead(403, { "Content-Type": "application/json" });
      return res.end(JSON.stringify({ error: "Blocked by SparrowX Edge WAF", clientIp }));
    }

    if (typeof next === "function") next();
  };
}

B. Add to your Express Server (server.js):

import express from "express";
import { sparrowxShield } from "./sparrowx-shield.js";

const app = express();

// Attach SparrowX Shield (Zero external dependencies!)
app.use(sparrowxShield({
  originIp: "64.29.17.65",   // Your server's real public IP
  siteDomain: "sparrowx.net", // Your domain
}));

app.get("/", (req, res) => res.send("Welcome! Shield Active."));
app.listen(3000, () => console.log("Server protected on port 3000"));

Step 4: Test & Verify Live on the 3D Global Traffic Mesh Globe

Run these test curl commands in your Terminal or Command Prompt. The green and red arcs will animate on your 3D globe in real time!

1. Test Legitimate Connection (200 OK):

curl -i http://localhost:3000/

→ Spawns glowing Green Arc on 3D Globe

2. Test WAF Interception (403 Blocked):

curl -i "http://localhost:3000/?q=UNION+SELECT+1"

→ Spawns glowing Red Arc on 3D Globe
