Github Profile Finder using Tailwind Css & Github API

Hello everyone, would really appreciate some feedback and any advise to the following issues i had. Thanks in advance!

1. hiding the API keys when only using Vanilla JS. I'm aware of dotenv with Node but was having some trouble trying to get it to work (haven't worked with node before). I know its not good practice to include these in the repos but thought it would be ok for this challenge as I am still researching and learning.
2. Ternary operator within template literals. As of now, if a profile searched has no Bio, it will just say NULL. My idea was to try to use a ternary operator to either generate the Bio from the profile data or to display "This profile has no bio." but has some issues implementing that. Similar goes for the blog and twitter details
