$ pgrep localhost:4000

Why doesn't this work?

By default, pgrep(1) will only match against the process name. If you want to match against the full command line, use the -f option:

$ pgrep -f localhost:4000

Have a look at the man page for pgrep. It is not just an alias for running ps with a bunch of columns and then greping the text output. It actually searches specific fields for values. By default, it only looks at the process name when doing a search and returns the PID. You can search the full command line by adding the -f option. You can also search several other fields that might be useful such as matching the terminal where a process is running or the group id.
