Looking for an alternative to x/deno_open

I'm using the --unstable-hmr--unstable-hmr option with Deno and whenever I modify code and save, this library opens a new window! I'm looking for a library that checks if the basepath (http://localhost:3000http://localhost:3000) is already open, if it is open, it doesn't do anything, meaning if http://localhost:3000/somethinghttp://localhost:3000/something was open, it still won't do anything and only if http://localhost:3000http://localhost:3000 wasn't open it opens it in a new browser window.
