Downstagram 
About
Downstagram is a simple command line tool to download and backup all your Instagram photos and videos.
Install
npm install -g downstagram
First run / OAuth Setup
After installation, Downstagram creates a configuration file in your home directory:
~/.downstagramrc
The file has the following fields and structure:
{
"auth": {
"client_id": "xxx",
"client_secret": "xxx",
"access_token": "<will be set after oauth setup>"
}
}
On the first run, Downstagram runs the OAuth setup. The browser will open up with Instagram's authorization page. Just accept the authorization request and copy paste the resulting access token into the terminal window.
After this step, Downstagram is ready to backup your photos. Just run the command with your username and it's done.

downstagram [-m| --metadata] [-o| --output] <username>

Development
