# strong-data-uri

[![Build Status](https://travis-ci.org/strongloop/strong-data-uri.png?branch=master)](https://travis-ci.org/strongloop/strong-data-uri)
[![NPM version](https://badge.fury.io/js/strong-data-uri.png)](http://badge.fury.io/js/strong-data-uri)

## Overview
strong-data-uri implements a parser for retrieving data encoded
in `data:` URIs specified by [RFC2397](http://www.ietf.org/rfc/rfc2397.txt),
as well as an encoder for those URIs.

## API

 - [decode](#decodeuri)
 - [encode](#encodedata-mediatype)

### decode(uri)

Call `dataUri.decode(uri)` to parse the payload of a data URI. The `uri`
argument expects a string.

```js
var dataUri = require('strong-data-uri');
var uri = 'data:text/plain;charset=iso-8859-1;base64,aGVsbG8gd29ybGQ=';

var buffer = dataUri.decode(uri);
console.log(buffer);
// <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
console.log(buffer.toString('ascii'));
// Hello world

console.log(buffer.mimetype);  // text/plain
console.log(buffer.mediatype); // text/plain;charset=iso-8859-1
console.log(buffer.charset);   // iso-8859-1
```

### encode(data, [mediatype])

Use `dataUri.encode(data, mediatype)` to build a new data URI. The `data`
argument can be a `Buffer` or a `String`. Strings are converted to buffers
using `utf-8` encoding.

If `mediatype` is not specified, then `application/octet-stream` is used
as a default if the data is a Buffer, and `text/plain;charset=UTF-8` if
the data is a String.

```js
var dataUri = require('strong-data-uri');

uri = dataUri.encode('foo');
console.log(uri);
// data:text/plain;charset=UTF-8;base64,Zm9v

uri = dataUri.encode(new Buffer('<foo/>', 'utf8'), 'text/xml');
console.log(uri);
// data:text/xml;base64,PGZvby8+
```
