<MuxUploader/>

Introduction

<MuxUploader> is React component for uploading files to Mux.

<MuxUploaderDrop> is an optional supporting React component for drop-in drag and drop and overlay. You can always configure your own drag and drop with <MuxUploader>.

If you are looking for a direct upload interface and a progress bar, you're in the right place.

Installation

If you're using npm or yarn, install that way:

Package manager

yarn add @mux/mux-uploader-react

or

npm i @mux/mux-uploader-react

Then, import the library into your application with either import or require:

import '@mux/mux-uploader-react';

or

require('@mux/mux-uploader-react');

Usage

const MuxUploaderWithMuxUploaderDropExample = () => {
  return (
    <div>
      <h1>Simple MuxUploader and Mux Uploader Drop Examples</h1>
      {/* Rounded upload button by itself. Displays upload progress in text as percentage. */}
      <MuxUploader endpoint="authenticated-url" style={{ '--button-border-radius': '40px' }}></MuxUploader>

      {/* Upload button by itself. */}
      <MuxUploader endpoint="authenticated-url"></MuxUploader>

      {/* Upload button with access to optional supplentary drag and drop features. */}
      <MuxUploaderDrop mux-uploader="uploader">
        <MuxUploader endpoint="authenticated-url" id="uploader"></MuxUploader>
      </MuxUploaderDrop>
    </div>
  );
};
