Did you check vercels logs?

these were the build logs Running build in Washington, D.C., USA (East) – iad1

And do you get something in the server logs? I would expect to see an error in the logs when you visit the page

do you have a vercel.json in your project?

seems like all requests are returning the base html

yes i have

 {
  "builds": [
    {
      "src": "package.json",
      "use": "@vercel/static-build",
      "config": {
        "distDir": "dist"
      }
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "dest": "/index.html"
    }
  ]
}

uhh are you not using nextjs?

no

am using vite react js and three js

doesn't vercel deploy other than next js

yes it can though this is a nextjs server, not a vercel server...

anyway it looks like you don't need a vercel.json, though. a typical vite app can simply be pushed to github and deployment to vercel will just work https://vitejs.dev/guide/static-deploy.html#vercel-for-git

that vercel.json currently configures that all requests are routed to index.html. hence your stylesheet and script requests are routed to index.html too

should i delete the vercel.json file

yes

what happens internally if vercel json file is removed

vercel.json holds the configuration that you use to tell vercel how to deploy. here you don't need it, but in advanced use cases you might

still nothing happened after deleting that json file

have you redeployed?

nvm looks like you did redeploy. then i cant help here, sorry – i don't use vite. hope someone else will be able to help

(though this is a nextjs server, not a vercel server. you probably will have more luck asking in the reactiflux server or a vite server if it exists)
