Image Data URI

Library to easily decode/encode Data URI images

Installation

CLI

npm install image-data-uri -g

npx image-data-uri --help

Methods

• decode(dataURI)

imageDataURI.decode('data:image/png;base64,SOMEPNGDATAURI/wD/')// RETURNS{imageType: 'image/png',dataBase64: 'SOMEPNGDATAURI/wD/',dataBuffer: <Buffer89504e470d0a...>}

• encode(data, mediaType)

// Expects a Buffer of a image fileletdataBuffer=newBuffer(imageData);// PNG | GIF | etc.letmediaType='PNG';// RETURNS :: image data URI :: 'data:image/png;base64,PNGDATAURI/wD/'imageDataURI.encode(dataBuffer,mediaType)

• encodeFromURL(imageURL)

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

• outputFile(dataURI, filePath)

// Some image data uriletdataURI='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 URIletfilePath='./out/path/fileName';// Returns a PromiseimageDataURI.outputFile(dataURI,filePath)// RETURNS image path of the created file 'out/path/fileName.png'.then(res=>console.log(res))
