FB-Downloader

App for Downloading Facebook videos and images

Running the app

1. Install Google Chrome for Ubuntu

   $ wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
   $ echo "deb http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee /etc/apt/sources.list.d/google-chrome.list
   $ sudo apt-get update
   $ sudo apt-get install google-chrome-stable

2. Install xvfb to run Chrome headlessly

   $ sudo apt-get install xvfb

3. Download chromedriver and add it to path

   $ sudo apt-get install unzip
   $ wget -N http://chromedriver.storage.googleapis.com/2.35/chromedriver_linux64.zip
   $ unzip chromedriver_linux64.zip
   $ chmod +x chromedriver
   $ sudo mv -f chromedriver /usr/local/share/chromedriver
   $ sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver
   $ sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver

4. Install Redis server

$ sudo apt-get install redis-server

5. Start a worker process

   $ python3 worker.py

6. Start the Flask server

   $ export FLASK_APP=app.py
   $ flask run

NOTE: This two processes must run concurrently. I suggest that for now run these two in two different consoles.
