When deploying react app, the deployed site shows only background color

I have created a react app which displays default photos rom a flicker API and a search bar which fetches photos on search, all is working fine in my local but as soon as Iā€™m deploying it on github pages the deployed site only the background color is shown, can anyone help me, as Iā€™m a noobie so refrain from using jargons, explain like you will explain it to a 10th grader :joy::joy::joy:
