LED and resistor in series from +5V to digital in - General

Possibly a daft question and I've very likely missed something somewhere but any search just brings up variations on the "blink" sketch. I'm wiring up a toggle switch across a digital input and was hoping to put in (for purely aesthetic purposes) an LED. TO save writing code is it alright to to put the resistor and LED off the com pin of the toggle switch to the digital pin so that when the switch has +5V across it the LED comes on?
