file-uploader

Warning

Project being rewritten, some features like the admin API and some upload endpoints are unavailable on 0.9.5

Simple file uploader made on Crystal. I'm making this to replace my current File uploader hosted on https://ayaya.beauty which uses https://github.com/nokonoko/uguu Already replaced lol.

Features

• Temporary file uploads like Uguu
• File deletion link (not available in frontend for now)
• Chatterino and ShareX support
• Video Thumbnails for Chatterino and FrankerFaceZ (Requires ffmpeg to be installed, disabled by default)
• Rate Limiting
• Small Admin API that allows you to delete files, reset rate limits and more (Needs to be enabled in the configuration)
• Unix socket support if you don't want to deal with all the TCP overhead
• Automatic protocol detection (HTTPS or HTTP)
• Low memory usage: Between 6MB at idle and 25MB if a file is being uploaded or retrieved. It will depend of your traffic.

Usage

• Clone this repository, compile it using shards build --release and execute the server using ./bin/file-uploader.
• Change the settings file ./config/config.yml acording to what you need.

NGINX Server block

Assuming you are already using NGINX and you know how to use it, you can use this example server block.

server {
    # You can keep the domain prefixed with `~.` if you want
    # to allow users to use any domain to upload and retrieve
    # files. Like xdxd.example.com or lolol.example.com .
    # This will only work if you have a wildcard domain.
	server_name ~.example.com example.com;

	location / {
        proxy_pass http://127.0.0.1:8080;
        # This if you want to use a UNIX socket instead
		#proxy_pass http://unix:/tmp/file-uploader.sock;
        proxy_set_header X-Real-IP   $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host  $host;
		proxy_pass_request_headers      on;
	}

    # This should be the size_limit value (from config.yml)
	client_max_body_size 512M;

	listen 443 ssl;
	http2 on;
}
