React File Upload Button

A customizable React component for file uploads with drag-and-drop functionality, progress bar, and file type restrictions. This component allows users to click or drag a file to upload, shows upload progress, supports custom icons, and lets users delete files after a successful upload.

Features

• Drag-and-Drop or Click-to-Upload functionality
• File type and size restrictions with custom error messages
• Progress bar for showing upload progress
• Custom icons for different file types
• Callbacks for handling errors and file upload events
• CSS customization through props

Installation

Install the package via NPM:

npm install react-file-upload-button

Usage

The UploadButton component is designed to be used out-of-the-box with zero configuration, but you can also customize it fully with various props.

Here’s a basic example of how to use the UploadButton component:

For a simple implementation, just add the component, and it will render with default settings. No additional configuration or CSS imports are needed.

import React from 'react'
import UploadButton from 'react-file-upload-button'

const App = () => (
    <div>
        <h1>Upload Your File</h1>
        <UploadButton />
    </div>
)

export default App

By default, the component will:

• Allow all file types for upload.
• Set a maximum file size of 10 MB (this can be changed).
• Show a basic drag-and-drop interface with upload progress.

Advanced Usage with Custom Props

To customize the upload experience, you can pass various props to control file type restrictions, size limits, styles, custom icons, and callbacks for handling events like errors and file uploads.

Here’s an example with all possible props:

import React from 'react'
import UploadButton from 'react-file-upload-button'

const App = () => (
    <UploadButton
        maxSizeMB={5}
        restrictFileSize={true}
        allowedFileTypes={[".pdf", ".jpg", ".png"]}
        uploadText={<strong style={{ color: 'blue' }}>Click or Drag to Upload Files</strong>}
        subText="Only PDF, JPG, and PNG files are allowed"
        uploadStyles={{ border: '2px dashed green', padding: '20px' }}
        progressStyles={{ backgroundColor: 'lightblue' }}
        errorStyles={{ fontStyle: 'italic', color: 'darkred' }}
        fileIcons={{
            pdf: <img src="pdf-icon.png" alt="PDF" style={{ width: '24px', height: '24px' }} />,
            image: <img src="image-icon.png" alt="Image" style={{ width: '24px', height: '24px' }} />,
            excel: <img src="excel-icon.png" alt="Excel" style={{ width: '24px', height: '24px' }} />,
            default: <img src="default-icon.png" alt="File" style={{ width: '24px', height: '24px' }} />
        }}
        fileTypeNotAllowedText="File type not supported. Please use PDF, JPG, or PNG."
        restrictFileSizeText="File too large. Max size is 5MB."
        FileSizeExceededButAllowedText="File size exceeds 5MB but will be uploaded."
        progressBarInterval={200}
        uploadFileIcon={<svg width="32" height="32" viewBox="0 0 24 24" fill="currentColor" xmlns="http://www.w3.org/2000/svg">
         <path d="M12 2L6.5 7.5H10V15H14V7.5H17.5L12 2Z" />
         <path d="M18 18H6V20H18V18Z" />
        </svg>}
        onError={(error) => console.log("Error:", error)}
        onFileUpload={(file) => console.log("File uploaded:", file)}
    />
)

export default App

In this example:

• File Restrictions: Limits uploads to PDF, JPG, and PNG files and restricts the maximum file size to 5MB.
• Custom Styling: Applies custom styles to the upload area, progress bar, and error messages.
• Icons: Displays different icons for each file type (PDF, image, Excel) and a default icon for others.
• Custom Text: Changes the default upload text and subtext messages.
• Callbacks:
  • onError: Logs errors when there is an issue with the file upload.
  • onFileUpload: Logs details when a file is successfully uploaded.

Props

Customization

• File Type Icons: Provide custom icons for different file types (e.g., PDF, images) by passing SVG or image elements in fileIcons.
• Error Messages: Customize error messages for unsupported file types and oversized files.
• Style Overrides: Apply custom styles directly to the upload area, progress bar, and error messages.
• Callbacks: Use onError and onFileUpload to handle errors and get the uploaded file data.
