How to deploy this on vercel or run it locally

Hey, I am kinda a newbie, would like to ask you guys how can I enter / deploy the same website as github1s.com on vercel or heroku. After running yarn, yarn build, yarn dev. The page served on localhost://5000 is like the below photo only. Even if I add localhost:5000/myrespo/myfolder, nothing is being shown.


Start by reproducing the reported commands: yarn, yarn build, and yarn dev, then inspect the localhost:5000 behavior described in the issue. Review the existing project instructions and deployment configuration, if present, to determine what local routing and Vercel or Heroku deployment steps should be documented. Done means a newcomer can run the site locally and follow clear deployment instructions.
