Deploy the modern Traccar web application on Vercel

[emmanuelh-dev]

I now have the backend on a Digital Ocean droplet, accessible at https://api.gonzher.com. Currently, I'm working on uploading the frontend to https://gps.gonzher.com, which will be hosted on Vercel.

However, I encountered an error: https://gps.gonzher.com/api/server 404 (Not Found). Strangely, this error only occurs in production. When I upload the repository to Vercel in development, this error doesn't appear.

Here's a snippet from my vite.config.file:

server: {
  port: 3000,
  proxy: {
    '/api/socket': 'ws:https://api.gonzher.com/',
    '/api': 'https://api.gonzher.com/',
  },
},
build: {
  outDir: 'build',
},

Proxy is only used for development.
