the repo is called 'cdn' because it's a short name. This is just a HTTP server made for file sharing. With some nice features...

• Modern UI

• Automatic scaling and responsive design with vanilla CSS and less than 40 lines of JS.

• Supports large files and video streaming.

• Automatic thumbnail generation for images and videos.

• Custom-made icon font, 99.65% more space efficient than font-awesome.

• Efficient golang back-end uses only 200 mb of RAM with 10 concurrent unique HD video streams.

• Full streaming is supported, so you can start watching videos before they are fully downloaded.

• When no connections are active, the server uses too little CPU to measure.

• only 115 lines of JavaScript, no dependencies.
• No frameworks, no libraries, no dependencies.
• Works on all browsers, with interactive UI.
• Users can sort files by name, size, date, type.
• Automatic thumbnail resizing using back-end image processing.

Clone the repository and build it with Go. Make sure you have Go installed on your system.

git clone git.sophuwu.com/cdn
cd cdn
go build -ldflags="-w -s" -trimpath -o build/

The binary will be created in the build/ directory.

To run the server, you need to set the environment variables for the port, address, HTTP directory, and database path. You can do this in your terminal or create a .env file.

• PORT: The port on which the server will listen (default: 8080).
• ADDR: The address on which the server will listen (default: 127.0.0.1).
• HTTP_DIR: The directory to serve.
• DB_PATH: The Database to cache generated thumbnails.

export PORT=8069
export ADDR=0.0.0.0
export HTTP_DIR=/path/to/your/files
export DB_PATH=/dir/dir/thumbnails.db
./build/cdn

PORT=8069 ADDR=0.0.0.0 HTTP_DIR=/path/to/your/files DB_PATH=/dir/dir/thumbnails.db ./build/cdn

sudo install ./build/cdn /usr/local/bin/cdnd

Edit the cdnd.service file and put it in /etc/systemd/system/. Make sure to set the correct paths for HTTP_DIR and DB_PATH.

If you prefer to write the service file manually, here is an example:

[Unit]
Description=File Sharing HTTP Server
After=network.target

[Service]
WorkingDirectory=/home/httpuser/files
ExecStart=/usr/local/bin/cdnd
Type=simple

User=httpuser

Environment=DB_PATH=/home/httpuser/files.db
Environment=HTTP_DIR=/home/httpuser/files
Environment=PORT=9889
Environment=ADDR=127.0.0.1

[Install]
WantedBy=multi-user.target

Then run:

sudo systemctl daemon-reload
sudo systemctl enable cdnd
sudo systemctl start cdnd
