Dropzone UI (express server-side)

Server side implementation for uploading files built with Express.js.

Run server

Follow the instructions to run the server.

#clone this repository
git clone https://github.com/dropzone-ui/file-upload-server-side.git

#install dependencies
npm install

#run server on development mode
npm run start

Congrats! you are done!. Your server is now running on port 2800. So, the url endpoint that must be given to Dropzone component is http://localhost:2800/upload-my-file.

If you deploy your server, the url prop will change to http://<YOUR_SERVER_URL>/upload-my-file.

Frontend side

Now upload some files from a react app using dropzone-ui this way:

import React,{ useState} from "react";
import { Dropzone, FullScreenPreview, FileItem } from "@dropzone-ui/react";

const SERVER_URL = "http://localhost:2800";

const Example = props =>{
    const [files, setFiles] = useState([]);
    const updateFiles = (incommingFiles) => {
      console.log("incomming files", incommingFiles);
      setFiles(incommingFiles);
    };
    const handleUpload=(responses)=>{
      //check the responses here
      console.log("responses", responses);
    }
    const onDelete = (id) => {
      setFiles(files.filter((x) => x.id !== id));
    };
 
    return (
      <Dropzone
        onChange={updateFiles}
        value={files}
        onUploadFinish={handleUpload}
        url={SERVER_URL + "/upload-my-file"}
      >
        {files.map((file) => (
          <FileItem
            {...file}
            key={file.id}
            onDelete={onDelete}
          />
        ))}
      </Dropzone>
    );
}
export default Example;
