Fngerprint Suite

When making HTTP requests in Node.js — especially for scraping, automation, or API testing — generating realistic browser headers can help avoid bot detection and improve success rates. That’s exactly what header-generator does.

Developed as part of the fingerprint-suite toolkit by Apify, this package lets you easily produce HTTP headers that mimic real browsers like Chrome, Firefox, or Safari. You can control which browsers, operating systems, and devices you want to simulate, so your requests more closely resemble genuine human traffic.

Instead of crafting headers manually or using static values that servers can easily flag, header-generator creates randomized, realistic HTTP headers — perfect for bots, crawlers, or automated clients that need to blend in.

⚙️ Steps to Install

📦 Install via npm

npm install header-generator

or

yarn add header-generator

(Uses the most recent version published on npm.)

🧪 Basic Usage Example

import { HeaderGenerator } from 'header-generator';

const hg = new HeaderGenerator({
  browsers: ['chrome', 'firefox'],
  operatingSystems: ['windows', 'linux'],
  devices: ['desktop'],
  locales: ['en-US']
});

const headers = hg.getHeaders();
console.log(headers);

This will produce a random but realistic set of HTTP headers similar to what a real browser would send.

🎯 Benefits (Why Use It?)

✅ Realistic Browser Headers
Simulates genuine browser request headers, which helps avoid basic bot detection.

✅ Highly Configurable
Supports filters for browsers, devices, OS, and locales so you can mimic specific traffic profiles.

✅ Easy to Use API
A simple class-based interface lets you get headers with minimal setup.

✅ Part of a Larger Fingerprinting Toolkit
Integrates well with other fingerprinting tools if needed.

👍 Pros & 👎 Cons

👍 Pros

• Generates realistic, randomized headers instead of static values.

• Easy configuration for browser families, locales, and platforms.

• Useful for web scraping, API automation, and testing.

• Good download count and maintained as part of a broader suite.

👎 Cons

• Only generates headers — no full browser fingerprinting or JS execution.

• Works best as part of a larger scraping strategy.

• Doesn’t handle request payloads, retries, or sessions — just headers.
