api

var DataUriStream = require('datauri-stream')

var ts = DataUriStream([opts])

opts.mime

An optional override for the mime type.

The mime type will be automatically detected otherwise, using the file-type module. It supports many file types.

If the source is not a file, then you'll want to supply the mime type.

ts
