How can I use docker to develop with 0.4.0? (i.e., how can I configure where /_build/ is exposed?)

[knpwrs]

I use docker for my local development, and I have the primary application port exposed on my machine. Since upgrading to 0.4.0, however, the network tab shows repeated attempts to /_build/ on a different port than what the rest of the app is served from:

How can I configure the port where /_build/ is served from so I can reliably expose it from Docker and the connection can succeed? I've tried tracing the code through to vinxi but wasn't able to determine the correct parameters for my configuration.

Try this

In your app.config.ts:

import { defineConfig } from "@solidjs/start/config";

export default defineConfig({
  vite({ router }) {
    if (router === "client") {
      return {
        server: {
          hmr: {
            port: 3001,
          },
        },
      };
    }
    return {};
  },
});

And in your docker-compose.yml:

ports:
      - 3001:3001
