Welcome to the best way to scrape using N8n

A Web Scraper framework for N8n

N8n Ultimate Scraper: Scraper for N8n builders

N8n Ultimate Scraper is an open-source framework designed for N8n builders who want to use an efficient and scalable scraper for their projects.

Our web scraper can find any data displayed on a webpage and can also use cookies to log in to the targeted webpage.

How It Work

The scraper takes the following input parameters:

• Subject (e.g., Hugging Face)
• Domain name/website (e.g., github.com)
• Targeted data (e.g., number of followers)
• Website cookies (optional for authentication)

The result of this request will be a structured JSON containing the number of followers on the Hugging Face GitHub page.

🚀 Getting Started

Docker Compose Setup for n8n and Selenium This repository contains a Docker Compose configuration for deploying n8n and Selenium standalone Chrome services.

Follow these steps to deploy the services using Docker Compose:

Prerequisites

1. Docker: Ensure Docker is installed on your system. You can download it from here.
2. Docker Compose: Ensure you have Docker Compose installed. You can check by running:

   docker-compose --version

Clone the Repository

Start by cloning the repository that contains the docker-compose.yml file and the .env file.

git clone https://github.com/Touxan/n8n-ultimate-scraper.git
cd n8n-ultimate-scraper

Configure the Environment Variables

Modify the .env file in the root directory modify the necessary environment variables for n8n and selenium.

# .env
# N8n Variables
N8N_BASIC_AUTH_ACTIVE=true
N8N_BASIC_AUTH_USER=n8nuser
N8N_BASIC_AUTH_PASSWORD=n8npassword

# Selenium Variables
HTTP_PROXY=http://proxyAdress:port
HTTPS_PROXY=http://proxyAdress:port

Make sure to replace n8nuser and n8npassword with more safer values. Make sure to replace proxyAddress and port with the actual values for your proxy.

Deploying the Services

To deploy the n8n and selenium services, run the following command:

docker-compose up -d

This will:

• Spin up the n8n service and expose it on port 5678.
• Spin up the selenium Chrome standalone service and expose it on port 4444.
• Connect both services on a custom Docker network.

Accessing the Services

• n8n: You can access n8n by navigating to http://localhost:5678 in your browser.

• Workflow: You can import on your n8n the Selenium_Ultimate_Scraper_Workflow.json and activate it

Request the workflow

To request the workflow you can start with this cur command :

curl -X POST http://localhost:5678/yourwebhookid \
-H "Content-Type: application/json" \
-d '{
  "subject": "Hugging Face",
  "Url": "github.com",
  "Target data": [
    {
      "DataName": "Followers",
      "description": "The number of followers of the GitHub page"
    },
    {
      "DataName": "Total Stars",
      "description": "The total numbers of stars on the different repos"
    }
  ],
  "cookies": []
}'

Or to just scrap a url :

curl -X POST http://localhost:5678/webhook-test/67d77918-2d5b-48c1-ae73-2004b32125f0 \
-H "Content-Type: application/json" \
-d '{
  "Target Url": "https://github.com",
  "Target data": [
    {
      "DataName": "Followers",
      "description": "The number of followers of the GitHub page"
    },
    {
      "DataName": "Total Stars",
      "description": "The total numbers of stars on the different repo"
    }
  ],
  "cookies": []
}'

Stopping the Services

To stop the running containers:

docker-compose down

This will stop and remove the containers, but your data will be persisted in the n8n_data volume.

Cookies Extraction

To extract cookies in the correct format for using a logged session with the scraper, you can use the extension provided in the repository.
