Setup

> git clone https://github.com/sujpac/youtube-api.git
> cd youtube-api
> virtualenv env
> source env/bin/activate

Go to the Google Console and create a new project. Go to the Library tab and enable the YouTube Data API v3 API. Then, go to the Credentials tab and do the following:

1. Create OAuth client ID credentials (to be used by scrape_video_comments.py) and choose desktop as the application type.
2. Download the client secrets file for the newly created OAuth credentials. Rename it to client_secret.json, and move to the youtube-api project directory.

> mv [downloads]/client_secret_10927*.apps.googleusercontent.com.json youtube-api/client_secret.json

3. Create API Key credentials (to be used by get_playlist_duration.py).
4. Safely store your API key by setting an environment variable in your .zshrc (or whatever your shell configuration file is).

> echo 'export YT_API_KEY="[insert-your-API-key-here]"' >> ~/.zshrc
> source ~/.zshrc
