# pull-file-reader [](https://david-dm.org/tableflip/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](https://github.com/maxogden/filereader-stream) by [@maxogden](https://github.com/maxogden).
# install
Use it with npm & [browserify](https://github.com/substack/node-browserify)
```bash
npm install pull-file-reader
```
# example
```js
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
```js
var fileReader = require('pull-file-reader')
var source = fileReader(file, [options])
```
`fileReader` is a [pull stream](https://github.com/pull-stream/pull-stream) [source](https://github.com/pull-stream/pull-stream#source-aka-readable).
`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
```
npm install
npm test
```
then open your browser to the address provided, open your JS console, and drag and drop files onto the page until the test suite passes/fails
