A basic link shortening service written in go. Please consider as a work-in-progress.

1. Edit the config.json file
2. Run ./go-link-shortener -config=/path/to/your/config
3. Shorten an url with /api/v1/new/?url=[your.url.com]
   • Don't forget to add & escape the https:// part if you really want it (otherwise it will default to http://)
4. Use the returned address

If you want to run it as a service, install_or_update.sh will set up everything in a nice systemd service. Worry free!

1. Clone the project
2. cd go-link-shortener
3. sudo ./install_or_update.sh

There is a minimalist UI to quickly minify links served at /ui

You can test the demo at https://belv.al/ui

On a single vCore machine with 1GB of RAM and behind a Nginx proxy using SSL (so a real scenario).

Using the Apache benchmarking tool:

ab -n 1000 -c 50 https://belv.al/82dbd (1000 requests, 50 concurrents):

I ran tests without Nginx and timings were below 70ms so it's quite fast.
