node-base64-image

Download images from remote URLs or use local images and encode/decode them to base64

To install
npm install node-base64-image --save

To run tests
npm test

Usage

Require the library in your .js file
var base64 = require('node-base64-image');

Download and encode an image

var options = {string: true};

base64.base64encoder('www.someurl.com/image.jpg', options, function (err, image) {
    if (err) {
        console.log(err);
    }
    console.log(image);
});

Encode a local image

var path = __dirname + '/../test.jpg',
          options = {localFile: true, string: true};

base64.base64encoder(path, options, function (err, image) {  
    if (err) { console.log(err); }  
    console.log(image);  
});  

Parameters

• url (string) - the url of the image to be downloaded and encoded.
• options (object)
  • if string is passed is with 'true', the image returned will be a base64 string. Otherwise, the base64 buffer is returned.
  • if localFile is passed is with 'true', a local image instead of a remote one will be used
• callback (function) - the callback will contain the err object and the encoded image object.

Decode and write a base64 encoded image to disk

var options = {filename: 'test'};
var imageData = new Buffer('/9j/4AAQSkZJRgABAQAAAQABAAD...', 'base64');

base64.base64decoder(imageData, options, function (err, saved) {
    if (err) { console.log(err); }  
    console.log(saved);    
});  

Parameters

• imageData (buffer) - the base64 image buffer.
• options (object) - contains the 'filename' property; this will be the written image file.
• callback (function) - the callback will contain the err object and the 'successful save' string.
