# node-base58 [](http://travis-ci.org/jimeh/node-base58)
|
|
|
|
A Base58 encoding and decoding library for [Node.js].
|
|
|
|
[node.js]: http://nodejs.org/
|
|
|
|
## What?
|
|
|
|
Base58 allows you to represent a numeric value with fewer characters, useful
|
|
for short URLs among other things. Flickr is one the biggest sites that makes
|
|
use of it for short photo URLs.
|
|
|
|
For example `6857269519` becomes `brXijP` when Base58 encoded, and hence the
|
|
Flickr short URL is: [`http://flic.kr/p/brXijP`](http://flic.kr/p/brXijP)
|
|
|
|
## Installation
|
|
|
|
npm install base58
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var Base58 = require('base58');
|
|
Base58.encode(6857269519); // 'brXijP'
|
|
Base58.decode('brXijP'); // 6857269519
|
|
```
|
|
|
|
## Credit
|
|
|
|
This package is more or less a port of the [Base58][gem] Ruby Gem by the same
|
|
name.
