Basic Example with uploading.

• if onUpload specified then onChange called with onUpload result

import React from 'react'
import FileInput, {UploadArea} from '@idui/react-file-input'

// if multiple then here would be files array
const upload = (file) => {
    // should return Promise
    return fetch('http://example.com', {
        method: 'POST',
        body: file
    }).then(response => response.json().data.src)
};

function Example() {
    const [src, setSrc] = useState();
    const [isUploading, setUploading] = useState();
    
    const handleChange = (newSrc) => {
        setUploading(false);
        setSrc(newSrc)
    };

    return <UploadArea>
        <FileInput
            accept="image/*"
            onStartUploading={() => setUploading(true)}
            onUpload={upload}
            onChange={handleChange}
            onError={() => setUploading(false)}
            maxFileSize={10}
        />
        {src ? <img alt="" src={src}/> : <span>Drop file here or click to upload</span>}
