Immediate listening for connections

Description

I’m using Vite with Electron, and my npm run dev command runs vite and electron . at the same time. Electron tries to connect to the Vite dev server before it’s ready, and gets an ERR_CONNECTION_REFUSED.

Suggested solution

It would be great if Vite could immediately start listening to requests and respond once it’s ready to

This is not possible. Vite needs to load/resolve config before server start.

Also this does not solve your problem. Even if the dev server listens as quickly as possbile, it is not guaranteed to be started before electron accesses.

FYI you could use a plugin like this to do something after the dev server started to listen to a port.

const p = {
  name: '',
  configureServer(server){
    server.httpServer.once('listening', ()=>{
        // here
    })
  }
}

By the way, thank you so much for suggesting to make a plugin! Works great:

const plugin = {
  name: 'electron-start',
  configureServer(server) {
    server.httpServer?.once('listening', () => {
      console.log('\nStarting Electron...')
      const child = exec('NODE_ENV=development electron .')
      child.stdout?.pipe(process.stdout)
      child.stderr?.pipe(process.stderr)
    })
  },
}
