React-Uploady
Modern file uploading - components & hooks for React
README
Modern file-upload components & hooks for React.
Contents
Intro
React-Uploady is a lightweight library - enabling you to build (client-side) file-upload features with just a few lines of code.
Uploady provides the foundations needed to upload files from the browser - The rest is up to you.
The philosophy behind this library is that it should be as simple as possible to use, yet customizable at every point.
You can start simple, or you can configure just about every aspect of the upload flow.
For this purpose, there are components, hooks, and plenty of features.
You get to choose which ones you need and only install the dependencies required (See Packages details below)
React-Uploady has a small footprint (by design) with very few (and small) dependencies.

Discussions
Please check the discussions area here in Github. If you have a question about use-cases or flows you'd like to achieve with Uploady, discussions is the place to look for existing answers or add your own.
If you're using Uploady in Production, please drop a comment here. It's always great to hear how people and companies use it.
Installation
React-uploady is a mono-repo, and as such provides multiple packages with different functionality.
For React applications, at the very least, you will need the Uploady provider:
- ``` sh
- #Yarn:
- $ yarn add @rpldy/uploady
- #NPM:
- $ npm i @rpldy/uploady
- ```
If you wish to use the uploading mechanism (no UI), at the very least, you will need the Uploader:
- ``` sh
- #Yarn:
- $ yarn add @rpldy/uploader
- #NPM:
- $ npm i @rpldy/uploader
- ```
After that, you can add additional packages as needed. See below for more details.
Packages
Main Packages
@rpldy/uploader - The processing and queuing engine

Examples
For specific usage, see documentation in the relevant package README file.
For upload options, see the @rpldy/uploady docs.
Simple Upload Button
This example shows how you add Uploady and UploadButton to your app.
This is all it takes to get file uploading to work in your React application.
- ``` js
- import React from "react";
- import Uploady from "@rpldy/uploady";
- import UploadButton from "@rpldy/upload-button";
- const App = () => (<Uploady
- destination={{ url: "https://my-server/upload" }}>
- <UploadButton/>
- </Uploady>);
- ```
Custom Upload Button
In case you want to use your own component as the upload trigger, use the asUploadButton HOC:
- ``` js
- import React from "react";
- import Uploady from "@rpldy/uploady";
- import { asUploadButton } from "@rpldy/upload-button";
- const DivUploadButton = asUploadButton((props) => {
- return <div {...props} style={{ cursor: "pointer" }}>
- DIV Upload Button
- </div>
- });
- const App = () => (<Uploady
- destination={{ url: "https://my-server/upload" }}>
- <DivUploadButton/>
- </Uploady>);
- ```
Progress Hook
- ``` js
- import React from "react";
- import Uploady, { useItemProgressListener } from "@rpldy/uploady";
- import UploadButton from "@rpldy/upload-button";
- //must be rendered inside
- const LogProgress = () => {
- useItemProgressListener((item) => {
- console.log(`>>>>> (hook) File ${item.file.name} completed: ${item.completed}`);
- });
- return null;
- }
- const App = () => (<Uploady
- destination={{ url: "https://my-server/upload" }}>
- <LogProgress/>
- <UploadButton/>
- </Uploady>);
- ```
Add support for resumable(tus) uploads
- ``` js
- import React from "react";
- import TusUploady from "@rpldy/tus-uploady";
- import UploadButton from "@rpldy/upload-button";
- const App = () => (<TusUploady
- destination={{ url: "https://my-tus-server/upload" }}
- chunkSize={2142880}
- sendDataOnCreate>
- <UploadButton/>
- </TusUploady>);
- ```
Add support for chunked uploads
Can be used with servers that support chunked uploads
- ``` js
- import React from "react";
- import ChunkedUploady from "@rpldy/chunked-uploady";
- import UploadButton from "@rpldy/upload-button";
- const App = () => (<ChunkedUploady
- destination={{ url: "https://my-server/upload" }}
- chunkSize={5242880}>
- <UploadButton/>
- </ChunkedUploady>);
- ```
Important Concepts
Upload Options
These are the options that are passed to the uploader to configure aspects of the upload process.
For example, whether files can be grouped in a single request (by default, no).
Upload Options are typically passed to the Uploady instance. But these can be overridden. For example, by props passed to the upload button.
Or even during upload processing.
Destination
Passed as a part of the upload options. It's an object that is used to configure the end-point where the files will be uploaded to.
Its type is defined here.
See more information in the Uploady README.
At the very least, a destination should contain a URL property with the server endpoint.
Enhancer
- ``` js
- (uploader: UploaderType, trigger: Trigger<mixed>) => UploaderType
- ```
Enhancers are functions that can enhance an uploader instance. They are also passed as part of the options given to the Uploady instance.
As they are applied when the uploader instance is created, they can change the way uploader does things or pass different defaults.
See this guide for practical information and sample code.
Batch
When a file or files are handed over to the uploader, they are grouped into a batch.
This batch will have its own lifetime events.
With a batch ID, it is possible to cancel all files that are part of it. It can also be used to retry all files in the batch (see @rpldy/retry).
BatchItem
Each file (or URL) added to the uploader is wrapped by a BatchItem object. They will have a unique ID within the life-time of the uploader instance.
A BatchItem has its own lifetime events.
Resumable Uploads
Your server will also have to support the same protocol for this to work, of course.
See the @rpldy/tus-uploady documentation for more details.
UMD Bundles
React-uploady is also available on CDNs such as unpkg.com and jsdelivr.com
See this guide for more information on how to use.

everything | https://cdn.jsdelivr.net/npm/@rpldy/uploady/umd/rpldy-all.umd.min.js |
You will most likely need the polyfill (core js) bundle as well (load it first):
- core bundles -> https://cdn.jsdelivr.net/npm/@rpldy/uploady/umd/polyfills-bundle.js
- everything bundle -> https://cdn.jsdelivr.net/npm/@rpldy/uploady/umd/polyfills-all-bundle.js

everything | https://unpkg.com/@rpldy/uploady/umd/rpldy-all.umd.min.js |
You will most likely need the polyfill (core js) bundle as well (load it first):
- core bundles -> https://unpkg.com/@rpldy/uploady/umd/polyfills-bundle.js
- everything bundle -> https://unpkg.com/@rpldy/uploady/umd/polyfills-all-bundle.js
Note that unpkg does a redirect to the latest version in case the URL doesn't already contain it. So don't copy any of the URLs above into your code.
Instead, load them in the browser first and then copy the final URL from there (after the redirect).
