This uploading wrapper remains fully functional and can be a great fit for your projects, especially if you have specific needs for jQuery. However, we recommend exploring our new React File Uploader to access the latest features and improvements.
This React component helps you integrate Uploadcare jQuery File Uploader into your React app natively; props management and lazy loading are bundled.
The component allows users to upload files from any file system and device, social media, cloud storage, and more. Best-in-class for image upload. All that without any backend code that’s usually required to handle uploads.
npm i @uploadcare/react-widget
import { Widget } from "@uploadcare/react-widget";
<Widget publicKey="YOUR_PUBLIC_KEY" />;or
import { Panel } from "@uploadcare/react-widget";
<Panel publicKey="YOUR_PUBLIC_KEY" />;To use this component, get an API key from your Uploadcare project.
Uploadcare account provides services for file uploads, transformations, CDN
delivery, as well as APIs. After signing up, you'll see Dashboard
where you can manage projects. Each Project is identified by its public key.
Replace YOUR_PUBLIC_KEY with your project’s Public API Key and you are all
set.
You can refer to our integration guide for more details.
By default, npm and other package managers import the full (all locales) CommonJS or ESM bundle.
To reduce your bundle size, you can also import one of the following:
- The english-only bundle (saves ~27% in bundle size) as
@uploadcare/react-widget/en - The minified all-locales bundle (saves ~44% in bundle size) as
@uploadcare/react-widget/min - The minified english-only bundle (saves ~60% in bundle size) as
@uploadcare/react-widget/en-min
Set an array of file UUID/group UUID/CDN URL/File Instance/Group Instance as a value.
<Widget value='9dd2f080-cc52-442d-aa06-1d9eec7f40d1' />
<Widget value='9dd2f080-cc52-442d-aa06-1d9eec7f40d1~12' />
<Widget value={[

]} />Set a function to be called after a file is uploaded and ready.
Set a function to be called after a new file is selected.
Set a function to be called after dialog is opened.
Set a function to be called after dialog is closed.
Set a function to be called after tab is changed.
The option can be used to set metadata object associated with the uploaded file.
Note that metadata supports string values only, any non-string value will be converted to string, including boolean, number, null and undefined.
WARNING: If this option is specified, option metadataCallback will be overridden (without merging).
This is opposite from the uploadcare-widget's behavior.
See Metadata docs for details.
Defines the function that specifies the actual metadata object a file uploader should use to associate with the uploaded file. It's helpful in the case of dynamic metadata object.
Note that metadata supports string values only, any non-string value will be converted to string, including boolean, number, null and undefined.
See Metadata docs for details.
Add custom tabs for a widget.
function myTab(container, button, dialogApi, settings, name, uploadcare) {
...
}
<Widget customTabs={{ tabname: myTab }} />Since custom tabs are global internally, any local property change will affect all the widget instances. So we're highly recommend not to redefine tab constructors and not to have different constructors under the same name.
Note that we added the fifth argument to the custom tab constructor — an
uploadcare object. The widget is lazily-loaded, so you don’t have to import
uploadcare-widget separately for your custom tab.
Remember that you also need to include your custom tab in the tabs prop to
make it work:
<Widget customTabs={{ tabname: myTab }} tabs='tabname' />Add Image Editor
- Install
uploadcare-widget-tab-effectspackage
npm i uploadcare-widget-tab-effects- Import one of the bundles:
uploadcare-widget-tab-effects/reactfor all-locales bundleuploadcare-widget-tab-effects/react-enfor english-only bundle
import effects from 'uploadcare-widget-tab-effects/react'
// or
// import effects from 'uploadcare-widget-tab-effects/react-en'- Pass the
effectsobject to thecustomTabsprop:
<Widget previewStep customTabs={{ preview: effects }} />Set validators for a widget. Validator is a JavaScript function that
receives a fileInfo object for each uploaded file and throws an exception if
that file doesn't meet validation requirements.
const fileTypeLimit = (allowedFileTypes: string) => {
const types = allowedFileTypes.split(' ')
return function(fileInfo: FileInfo) {
if (fileInfo.name === null) {
return
}
const extension = fileInfo.name.split('.').pop()
if (extension && !types.includes(extension)) {
throw new Error('fileType')
}
}
}
const validators = [fileTypeLimit('mp3 avi mp4')];
<Widget validators={validators} />Set a custom preloader. A preloader component shows up when the widget is being loaded.
Define a reference object to address the Widget API wrapper. Use it to access
these methods: value, openDialog, reloadInfo and getInput.
value()is the alias forwidget.value()openDialog()is the alias forwidget.openDialog()reloadIngo()is the alias forwidget.reloadInfo()getInput()returns widget's input element instance.
Example:
const Example = () => {
const widgetApi = useRef();
return (
<>
<button onClick={() => widgetApi.current.openDialog()}>
Click me
</button>
<Widget ref={widgetApi} publicKey=“demopublickey” />
</>
);
};Optional. Define a custom CSS for tabs opened in iframes (e.g., Facebook, Instagram, etc.). It can be a CSS string or an absolute URL to a CSS file.
// Via URL
<Widget tabs="facebook" tabsCss="https://site.com/styles/uc.tabs.css"/>
// Via plain CSS
<Widget tabs="facebook" tabsCss=".source-facebook { background: #1877F2; }"/>Note that all iframe tabs are opened via HTTPS, so linked CSS files should also be available over HTTPS.
Set an array of file UUID/group UUID/CDN URL/File Instance/Group Instance as a value.
<Panel value={[
'9dd2f080-cc52-442d-aa06-1d9eec7f40d1',
'https://ucarecdn.com/fdfe4e67-f747-4993-91f5-be21d6d3c1a6/',
'9ef9af26-7356-4428-b69c-1b920f947989~2'
]} />Set a function to be called whenever files state changes.
Set a function to be called whenever progress state changes.
Define a reference object to address the Dialog API wrapper.
interface DialogApi {
addFiles(type: string, files: any[]): void;
addFiles(files: Array<JQuery.Deferred<FileInfo>>): void;
switchTab(tab: string): void;
getFileColl(): CollectionOfPromises<FileInfo>;
hideTab(tab: string): void;
showTab(tab: string): void;
isTabVisible(tab: string): boolean;
onTabVisibility(callback: OnTabVisibilityCallback): void;
}jQuery File Uploader can be deeply customized to suit your UX/UI. You can define allowed upload sources, implement file validation, and more.
All the options defined in the widget options docs are also supported in the component as props (use the camelCase notation, you can find it under “Object key” in the referenced article).
Use the live jQuery File Uploader as a starting point and consider checking out the docs on widget configuration.
