base64-stream

Contains new Node.js v0.10 style stream classes for encoding / decoding Base64 data

Introduction

While Node.js has built-in support for Base64 data, it does not come with the ability to encode / decode data in a stream.

This library contains a streaming Base64 encoder and a streaming Base64 decoder for use with Node.js. These classes are written using the new Node.js v0.10 stream interfaces and are well covered with unit tests.

Usage

Installation

To install base64-stream

npm install base64-stream

Examples

This example encodes an image and pipes it to stdout.

var http = require('http');
var base64 = require('base64-stream');
 
var img = 'http://farm3.staticflickr.com/2433/3973241798_86ddfa642b_o.jpg';
http.get(img, function(res) {
    if (res.statusCode === 200)
        res.pipe(base64.encode()).pipe(process.stdout);
});

This example takes in Base64 encoded data on stdin, decodes it, an pipes it to stdout.

var base64 = require('base64-stream');
process.stdin.pipe(base64.decode()).pipe(process.stdout);

You may also treat encode / decode as classes, so the following is also valid:

var Base64Decode = require('base64-stream').decode;
var stream = new Base64Decode();
...

Requirements

This module currently requires Node v0.8 or higher. Support for versions prior to v0.10 is made possible by using the readable-stream module.

Testing
