Image Data URI

Library to easily decode/encode Data URI images

Installation

npm install image-data-uri

CLI

npm install image-data-uri -g

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: <Buffer 89 50 4e 47 0d 0a ...> }

- **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)

  // 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)

  // 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))

```
