config.js and connection.js files missing and snack expo not working

# Additional information: Question
I was looking around at some of the files and noticed there is not a /server/config/connection.js or /server/config/config.js available (maybe i'm just missing something)

Also the snack expo link is not working

Start by checking whether /server/config/connection.js and /server/config/config.js are expected project files, then inspect the repository's Expo Snack link and related setup. Done means the missing-file concern is resolved or clarified and the Snack link works, with any required setup documented.
