💉 loadstring

A lightweight Node.js utility to execute JavaScript from strings or remote URLs — inspired by Lua's loadstring().

---

⚙️ Requires Node.js v20 or higher

---

🚀 Features

• ✅ Run JavaScript from a string
• 🌐 Load & execute code from a remote URL
• 🧠 Smart load() function auto-detects string vs. URL
• ✨ Zero Dependencies
• ⚡ Simple, async-friendly API

---

📥 Installation

npm install loadstring

---

✨ Usage

1. Run a JavaScript string

const { loadString } = require('loadstring');
// import { loadString } from 'loadstring';

loadString(`console.log("Hello from string!");`);

loadString(`
  console.log("Log 1");
  console.log("Log 2");
`);

---

2. Run JavaScript from a URL

const { loadStringFromURL } = require('loadstring');
// import { loadStringFromURL } from 'loadstring';

loadStringFromURL('https://example.com/script.js');
// We recommend using pastebin links to inject yiur code via link (make sure u have pastebin link to the raw code)

If https://example.com/script.js contains:

console.log("🔥 Remote code executed!");

You’ll see:

🔥 Remote code executed!

---

3. Smart load() — automatically runs string or URL

const { load } = require('loadstring');
// import { load } from 'loadstring';

// Runs a code string
load('console.log("From string!")');

// Loads and runs from a remote URL
load('https://example.com/hello.js');

---

📘 API

loadString(code: string): void

Executes a string of JavaScript code.

---

loadStringFromURL(url: string): Promise<void>

Fetches JavaScript code from a remote URL and executes it.

---

load(input: string): Promise<void>

Smart loader — detects if the input is a URL and runs accordingly.

---

⚠️ Security Warning

This module uses new Function() under the hood.

❗️ Never run untrusted or user-generated input — this allows full code execution.
