filereader-stream

Given a HTML5 File object (from e.g. HTML5 drag and drops), turn it into a readable stream.

If you want this for FileLists then definitely check out fileliststream.

install

Use it with npm & browserify >= 3.0

$ npm install filereader-stream

example

var drop = require('drag-and-drop-files');
var concat = require('concat-stream');
var createReadStream = require('filereader-stream');

test('should read file when one is dropped', function(t) {
  drop(document.body, function(files) {
    var first = files[0]
    createReadStream(first).pipe(concat(function(contents) {
      // contents is the contents of the entire file
    }))
  })
})

usage

var createReadStream = require('filereader-stream'. [options]);

options is optional and can specify output. Possible values are:

• arraybuffer [default]
• binary
• dataurl
• text

You can also specify chunkSize, default is 8128. This is how many bytes will be read and written at a time to the stream you get back for each file.
