pull-file-reader

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

Heavily based on filereader-stream by @maxogden.

install

Use it with npm & browserify

npm install pull-file-reader

example

var drop = require('drag-and-drop-files')
var pull = require('pull-stream')
var fileReader = require('pull-file-reader')

drop(document.body, function (files) {
  var first = files[0]
  pull(
    fileReader(first),
    pull.collect(function (err, buffs) {
      var contents = Buffer.concat(buffs)
      // contents is the contents of the entire file
    })
  )
})

usage

var fileReader = require('pull-file-reader')
var source = fileReader(file, [options])

fileReader is a pull stream source.

options:

• chunkSize - default 1024 * 1024 (1MB) - How many bytes will be read at a time
• offset - default 0 - Where in the file to start reading

run the tests
