Expose server instance for integration with graphql-ws

[clayrisser]

I need to setup a websocket server, and I need access to the server instance to create it.

https://github.com/enisdenjo/graphql-ws

For example...

import * as ws from "ws";

const wsServer = new WebSocketServer({
  onestackServerInstance,
  path: '/api/graphql',
});

How can I access the onestackServerInstance?

Quick reply: In your vite.config.*, you can add a custom plugin with a configureServer hook to access the Vite dev server instance and extend its functionality.

const myServerPlugin = () => ({
  name: 'configure-server',
  configureServer(server) {
    // do something to the server
  },
})

export default defineConfig({
  plugins: [
    one(/* ... */),
    myServerPlugin(),
  ],
})

But I can think of a few issues that may make this unusable for your case:

• We have an internal h3 server acting as the "API gateway" for the dev server (legacy and we want to remove it), which might prevent added features from being exposed.
• What about production?

I think we should take a deeper look soon, maybe tomorrow.

We're on the way of removing the internal h3 server. #210 #199

h3 is removed now so it's all Vite.

We do need a generic way for people to hook into the server in both dev and prod. Vite doesn't provide this so maybe we should work with them a bit, but some basic middleware support would be nice. Ideally we can make it typed (Tanstack does good stuff here).
