This crawler automatically fetches the first post from a Facebook fanpage using Selenium WebDriver and saves the result to facebook_first_post.json.

Google Chrome browser

Installation

Clone the repository:
```
git clone <repo-url>
cd Crawler-FB
```

Environment Setup

Create a .env file in the project root with the following content:

FB_USERNAME=your_facebook_email_or_phone
FB_PASSWORD=your_facebook_password

Note: Do not share your .env or facebook_cookies.json files in git to protect your credentials.

Running the Crawler

cd crawler-fb

Run the crawler:

node crawler-fb/crawler-post.js <fanpage_url>

Example:

node node crawler-fb/crawler-post.js "http://exmaple.com" (website yout want crawler)

Username and password can be set via environment variables or passed as command-line arguments:
```
node crawler-post.js <fanpage_url> <unused> <unused> <username> <password>
```
