# file-dialog

[![npm version](https://img.shields.io/npm/v/file-dialog.svg?style=flat)](https://www.npmjs.com/package/file-dialog) [![PRs Welcome](https://img.shields.io/badge/PRs-welcome-brightgreen.svg)](CONTRIBUTING.md#pull-requests)

Directly call the file browser dialog from your code, and get back the resulting array of [FileList](https://developer.mozilla.org/en/docs/Web/API/FileList). Handy for when you need to post files via AJAX/Fetch. No more hacky hiding of `` elements. Support for Callbacks & Promises! 

- Supports ES6 Modules, CommonJS, AMD, and global

- Supports selecting multiple files and the file type 'accepts' attribute (see examples below)

- Support for all major browsers

- No jQuery needed, tiny (1.25 KB), with no dependencies

## Install

Supports both CommonJS and ES6 Modules

1. `npm install file-dialog`

2. `import fileDialog from 'file-dialog'` or `const fileDialog = require('file-dialog')`

Note: If you want to support older browsers make sure you have babel enabled.

### Classic `` includes

1. Include minified file-dialog.min.js via `<script>`

2. Module is binded to the global variable `fileDialog`

## Examples

Get a File via a promise and POST to server via Fetch

```javascript

fileDialog()

    .then(file => {

        const data = new FormData()

        data.append('file', file[0])

        data.append('imageName', 'flower')

        // Post to server

        fetch('/uploadImage', {

            method: 'POST',

            body: data

        })

    })

```

Allow user to select only an image file

```javascript

fileDialog({ accept: 'image/*' })

    .then(files => {

        // files contains an array of FileList

    })

```

Allow user to select only images or videos

```javascript

    

fileDialog({ accept: ['image/*', 'video/*'] })

    .then(files => {

        // files contains an array of FileList

    })

```

Allow user to select multiple image files at once

```javascript

fileDialog({ multiple: true, accept: 'image/*' })

    .then(files => {

        // files contains an array of FileList

    })

```

Classic callback version of the above

```javascript

fileDialog({ multiple: true, accept: 'image/*' }, files => {

    // files contains an array of FileList

})

```
