Python based CloudFlare bypass. Utilizes [VeNoMouS's CloudScraper](https://github.com/VeNoMouS/cloudscraper) project to bypass CloudFlare. All credit goes to him.
A Node.js wrapper for Python-based CloudFlare bypass functionality. This library is a JavaScript port of the popular cloudscraper Python library, designed to help developers bypass CloudFlare protection mechanisms in their Node.js applications.
CloudScraper.js provides a seamless way to make HTTP requests to websites protected by CloudFlare, handling JavaScript challenges, CAPTCHAs, and other protection mechanisms automatically. It's particularly useful for:
- Web scraping applications
- API integrations with CloudFlare-protected endpoints
- Automated testing of protected websites
- Data collection from sites with anti-bot protection
- Automatic CloudFlare bypass: Handles JavaScript challenges and CAPTCHAs
- Multi-platform support: Works on macOS, Linux, and Windows
- Virtual environment support: Automatic Python dependency management
- Easy installation: One-command setup with automatic dependency installation
- TypeScript support: Full type definitions included
- Multiple HTTP methods: GET, POST, COOKIE, and TOKENS support
This library requires both Python and Node.js. For detailed installation instructions, see INSTALLATION.md.
``bash`
npm install cloudscraper.js
The installation process will automatically:
- Check for Python installation
- Install Python if needed (macOS/Linux)
- Create virtual environment if required
- Install the cloudscraper Python library
`javascript
// ES6
import CloudScraper from "cloudscraper.js";
// CommonJS
const CloudScraper = require("cloudscraper.js").default;
const scraper = new CloudScraper({
usePython3: true, // Set to true if using python3, false for python
timeoutInSeconds: 10,
});
// Simple GET request
scraper
.get("https://example.com")
.then((response) => {
console.log("Status:", response.status);
console.log("Data:", response.text());
})
.catch((error) => {
console.error("Error:", error);
});
// POST request with data
scraper
.post("https://api.example.com", {
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ key: "value" }),
})
.then((response) => {
console.log(response.json());
});

⚠️ Early Development Phase
This library is currently in early development. While functional, it may have limitations and breaking changes as we continue to improve it. We're actively working on:
- Enhanced error handling
- Better performance optimization
- Additional HTTP methods support
- Improved documentation
- More robust CloudFlare challenge handling
We plan to release regular updates to improve functionality and maintain compatibility with the latest CloudFlare protection mechanisms.
