VanderWaal introduced the song live at VidCon in June 2017, and she released a music video of "Moonlight" on her YouTube Vevo channel the following month. The song received largely positive reviews.
VanderWaal began work on her first studio album, Just the Beginning in early 2017. When she released the first single from the album, "Moonlight", she commented on the song's meaning: "'Moonlight' is about somebody you know very well changing unnaturally over time right in front of you and pushing you away, so you want to help bring them back to their original self.
