Over the past decade, integral field units (IFUs) have revolutionized our approach to resolved star formation and feedback studies in nearby galaxies. Where we would typically be limited to observing tens of star-forming regions per galaxy to study the properties of their stars and gas, we can now perform these analyses with orders-of-magnitude better efficiency for hundreds to thousands many more regions over entire nearby galaxies. In particular, the combination of IFU spectroscopy with high spatial resolution photometry is proving to be a game changer for stellar feedback studies, because it allows us to quantify feedback from the bottom up, i.e. from individual massive stars up to their effects on galaxy-wide scales. I will showcase some of the most recent results in this area, and share some preliminary yet exciting results from a VLT/MUSE data set of the nearby galaxy NGC 300.
