Library to easily decode/encode Data URI images

Installation

``bash
npm install image-data-uri
`
CLI
`bash
npm install image-data-uri -g
`
`bash
npx image-data-uri --help
`

Methods

- decode(dataURI)
`javascript
imageDataURI.decode('data:image/png;base64,SOMEPNGDATAURI/wD/')

// RETURNS
{
imageType: 'image/png',
dataBase64: 'SOMEPNGDATAURI/wD/',
dataBuffer:
}
`

- encode(data, mediaType)
`javascript
// Expects a Buffer of a image file
let dataBuffer = new Buffer(imageData);

// PNG | GIF | etc.
let mediaType = 'PNG';

// RETURNS :: image data URI :: 'data:image/png;base64,PNGDATAURI/wD/'
imageDataURI.encode(dataBuffer, mediaType)
`

- encodeFromURL(imageURL)
`javascript
// Returns a Promise
imageDataURI.encodeFromURL('http://www.some-site.com/some-image.png')

// RETURNS image data URI :: 'data:image/png;base64,PNGDATAURI/'
.then(res => console.log(res))
`
- encodeFromFile(filePath)
`javascript
// Returns a Promise
imageDataURI.encodeFromFile('./some-file.png')

// RETURNS image data URI :: 'data:image/png;base64,PNGDATAURI/'
.then(res => console.log(res))
`
- outputFile(dataURI, filePath)
`javascript
// Some image data uri
let dataURI = 'data:image/png;base64,PNGDATAURI/';

// It will create the full path in case it doesn't exist
// If the extension is defined (e.g. fileName.png), it will be preserved, otherwise the lib will try to guess from the Data URI
let filePath = './out/path/fileName';

// Returns a Promise
imageDataURI.outputFile(dataURI, filePath)

// RETURNS image path of the created file 'out/path/fileName.png'
.then(res => console.log(res))
