react-file-drop
React component for Gmail or Facebook -like drag and drop file uploader. Drag files anywhere onto the window (or user defined "frame" prop)! Very extensible, provides many hooks so you can use it to develop any custom behavior that you desire.
fork: @loopmode/react-file-drop
This is a fork of the original react-file-drop library. It adds support for custom render function for wrappers, and enables it to be used in SVG context.
Furthermore, it accepts any kind of dropped content (not just files) and provides a third argument details
to the onDrop
callback.
V2 is out! See the changelog before upgrading
Demo/Example
http://sarink.github.io/react-file-drop/dist/Demo - A very simple demo with example code and sample CSS
By default, there are no styles! You must include some CSS if you want to see anything!
You can grab the demo CSS to get started
Browser support
✅ Chrome ✅ Firefox ✅ Safari ✅ IE 11 ✅ IE Edge
Typescript?
Yup! (For typing event handlers, use the native DragEvent for frame handlers, and the React lib's DragEvent for others)
Why?
I wanted that behavior like facebook, gmail, etc. have where a part of the page highlights immediately when you start dragging a file anywhere on the window. I couldn't find any React component that already did this, so, I made one.
Installation
npm install react-file-drop
Usage
import FileDrop from 'react-file-drop
How it works
First, you define the frame
prop (default is the document
), whenever the user begins dragging file(s) anywhere over this frame, the <div class="file-drop-target">
will be inserted into the DOM.
Next, define an onDrop
prop, whenever a user drops their files onto the target, this callback will be triggered.
Lastly, you'll need to style it. Check out the Styling section below for details.
Props
disabled - Boolean
If true, any drag/drop is ignored. No callbacks will be invoked.
onDrop - function(files, event)
Callback when the user drops files onto the target
Fork info: the third argument, details, has the signature {files:Array<String>, links:Array<String>, images:Array<String>, text:String, html:String}
onDragOver - function(event)
Callback when the user is dragging over the target. Also adds the file-drop-dragging-over-target
class to the file-drop-target
onDragLeave - function(event)
Callback when the user leaves the target. Removes the file-drop-dragging-over-target
class from the file-drop-target
dropEffect - String "copy" || "move" || "link" || "none" (default: "copy")
