React Images Uploader

React.js component for uploading images to the server.

Examples

Example for multiple images:

import React, { Component } from 'react';
import ImagesUploader from 'react-images-uploader';
import 'react-images-uploader/styles.css';
import 'react-images-uploader/font.css';

export default class MyUploader extends Component {
	render() {
		return (
			<ImagesUploader
				url="http://localhost:9090/multiple"
				optimisticPreviews
				onLoadEnd={(err) => {
					if (err) {
						console.error(err);
					}
				}}
				label="Upload multiple images"
				/>
		);
	}
}

Example for one picture:

import React, { Component } from 'react';
import ImagesUploader from 'react-images-uploader';
import 'react-images-uploader/styles.css';
import 'react-images-uploader/font.css';

export default class MyUploader extends Component {
	render() {
		return (
			<ImagesUploader
				url="http://localhost:9090/notmultiple"
				optimisticPreviews
				multiple={false}
				onLoadEnd={(err) => {
					if (err) {
						console.error(err);
					}
				}}
				label="Upload a picture"
				/>
		);
	}
}

import express from 'express';
import corsPrefetch from 'cors-prefetch-middleware';
import imagesUpload from 'images-upload-middleware';

const app = express();

app.use('/static', express.static('./server/static'));

app.use(corsPrefetch);

app.post('/multiple', imagesUpload(
	'./server/static/multipleFiles',
	'http://localhost:9090/static/multipleFiles',
	true
));

app.post('/notmultiple', imagesUpload(
	'./server/static/files',
	'http://localhost:9090/static/files'
));

app.listen(9090, () => {
	console.log('Listen: 9090');
