DumbDrop

A stupid simple file upload application that provides a clean, modern interface for dragging and dropping files. Built with Node.js and vanilla JavaScript.

No auth (unless you want it now!), no storage, no nothing. Just a simple file uploader to drop dumb files into a dumb folder.

Quick Start

Option 1: Docker (For Dummies)

# Pull and run with one command
docker run -p 3000:3000 -v ./uploads:/app/uploads dumbwareio/dumbdrop:latest

1. Go to http://localhost:3000
2. Upload a File - It'll show up in ./uploads
3. Celebrate on how dumb easy this was

Option 2: Docker Compose (For Dummies who like customizing)

Create a docker-compose.yml file:

services:
  dumbdrop:
    image: dumbwareio/dumbdrop:latest
    ports:
      - 3000:3000
    volumes:
      # Where your uploaded files will land
      - ./uploads:/app/uploads
    environment:
      # Explicitly set upload directory inside the container
      UPLOAD_DIR: /app/uploads
      # The title shown in the web interface
      DUMBDROP_TITLE: DumbDrop
      # Maximum file size in MB
      MAX_FILE_SIZE: 1024
      # Optional PIN protection (leave empty to disable)
      DUMBDROP_PIN: 123456
      # Upload without clicking button
      AUTO_UPLOAD: false
      # The base URL for the application
      # You must update this to the url you use to access your site
      BASE_URL: http://localhost:3000

Then run:

docker compose up -d

1. Go to http://localhost:3000
2. Upload a File - It'll show up in ./uploads
3. Rejoice in the glory of your dumb uploads

Note: The UPLOAD_DIR environment variable is now explicitly set to /app/uploads in the container. The Dockerfile only creates the uploads directory, not local_uploads. The host directory ./uploads is mounted to /app/uploads for persistent storage.

Option 3: Running Locally (For Developers)

For local development setup, troubleshooting, and advanced usage, see the dedicated guide:

Configuration

Environment Variables

• UPLOAD_DIR is used in Docker/production. If not set, LOCAL_UPLOAD_DIR is used for local development. If neither is set, the default is ./local_uploads.
• Docker Note: The Dockerfile now only creates the uploads directory inside the container. The host's ./local_uploads is mounted to /app/uploads and should be managed on the host system.
• BASE_URL: If you are deploying DumbDrop under a subpath (e.g., https://example.com/watchfolder/), you must set BASE_URL to the full path including the trailing slash (e.g., https://example.com/watchfolder/). All API and asset requests will be prefixed with this value. If you deploy at the root, use https://example.com/.
• BASE_URL must end with a trailing slash. The app will fail to start if this is not the case.

Security

Features

• Variable-length PIN support (4-10 digits)
• Constant-time PIN comparison
• Input sanitization
• Rate limiting with IP-based tracking
• Protection against IP spoofing attacks
• Configurable proxy trust for reverse proxy deployments
• File extension filtering
• No client-side PIN storage
• Secure file handling

Security Best Practices

1. PIN Protection: Always set a strong PIN when deploying publicly
2. Proxy Trust: Only enable TRUST_PROXY when behind a verified reverse proxy
3. HTTPS: Use HTTPS in production (handled by your reverse proxy)
4. File Extensions: Restrict allowed file types using ALLOWED_EXTENSIONS if possible
5. Regular Updates: Keep DumbDrop and its dependencies up to date
