Example

1. If you want to store the profile pic from facebook profile api to your server, you can use this. Lets take Mark Zuckerberg profile pic.

var save = require('savefilefromurl');
var Promise = require('bluebird');

//url for a mark photo

var url = "https://scontent-sin1-1.xx.fbcdn.net/v/t1.0-9/12208495_10102454385528521_4749095086285673716_n.jpg?oh=5828bbf762179e142d2bcb944c304d48&oe=57EA5B5C";
var path = "/var/www/profile/";
var filename = "picture";

var promise = [save.saveFile(url,path,filename)];
Promise.all(promise).then(function(success){

//YOU CAN BROWSE THE JPEG FILE OF MARK IN /var/www/profile/picture.jpg

},function(error){

//error

})

2. Similarly you can save profile photo from google plus or google books.

var save = require('savefilefromurl');
var Promise = require('bluebird');

//url for a book image
var url = "https://books.google.co.in/books/content?id=JV6rpwAACAAJ&printsec=frontcover&img=1&zoom=1&imgtk=AFLRE73LVBx1-f3abS0wLnz9yq9ts3enSCGWjYI3EVk2WTa378RVBkRbeviAGmKaG28SZcR59DbQDllEf9Kd00OoE3IlvxNreqMgNK-Ywl5qrCcTCGCAzVnM0TGB9WHvM6fJTV3KHGa-";

var promise = save.saveFile(url,"folder","small")
Promise.all(promise).then(function(success){
...
},function(error){
...
})
