Usage

dataurl.parse(string)

Parses a dataurl string. Returns an object with three properties:

  • data : unencoded data
  • mimetype : mimetype of the data, something like 'image/png'
  • charset : charset of the data, if specified

If the input string isn't a valid dataURL, returns false.

dataurl.stringify({mimetype, charset, data})

Converts some data to a dataurl string. Options expects up to four properties

  • data : Required
  • mimetype : Required
  • charset : Optional
  • encoded : Optional, whether to base64 encode the data. Defaults to true

dataurl.format and dataurl.convert are aliases to dataurl.stringify

require('dataurl/stream)(options)

Creates a Read/Write Stream for encoding data as a DataURL.

Options expects up to three properties:

  • mimetype : Required
  • charset : Optional
  • encoded : Optional

Resulting stream will emit a data event for the header, then emit 'data' events for each chunk (base64 encoded, if necessary) as they pass through.

Example:

fs.createReadStream(pathToSomeImage).pipe(
  dataurl.stream({ mimetype: 'image/png'})
).pipe(process.stderr, {end: false});
