A very minimal script to host a fully-fledged file upload & URL shortening service. It is under a 100 lines of Python code, and is fully customizable with an external configuration file.

It features:

File upload
URL shortening
Size limits
Time limits
A landing page
Customizable with an external file

Usage

You can push files to it using the following command: curl -F file=@your_file up.x1b.dev.com

You can shorten URL's by using this command and providing the target URL: curl -d "url=https://example.com" up.x1b.dev

After any action you will get a URL with a 6-character key like: https://up.x1b.dev.com/xg29a6

Requirements

To run this you will need the following packages:

Default Python packages (os, requests, etc.)
Flask
SQlite3

Setup

After installing the required packages, you can configure your instance, and run the main python script with: python3 main.py

Everything will be set up automatically for a first-time run.

Configuration

The example configuration file looks like this:

{
    "upload_folder": "./uploads",
    "max_file_size": 104857600,
    "expiration_time": 604800,
    "data_file": "data.db",
    "base_url": "http://localhost:5000/",
    "name": "up.x1b.dev"
}

And here is what the fields mean:

upload_folder - the folder where the uploads will be stored

max_file_size - maximum upload file size in bytes

expiration_time - how long files take to expire in seconds

data_file - sqlite3 database file

base_url - your domain url

name - what your website is called (doesn't have to be same as domain name)

Reverse proxy

You may want to set this up on a domain name, and not using the server IP. You can do this with a reverse proxy.

You can find documentation on how to set up a reverse proxy with nginx here.

Contribution

Feel free to open pull requests to implement features, or issues to request features / report problems. The only rule is to keep the main.py file under 100 lines of code.

Thanks for reading, and happy uploading!
