Reproduction

https://github.com/TechAkayy/nuxt-374

I was testing the previous closed issue - #135

Clone & install deps. Open nuxt.config.ts, and start dev-server. After re-start in 12 secs, HMR breaks and the client loses connection with the server. Try uncommenting the div in app.vue, HMR is not applied anymore, loses connection with nuxt devtools too.

nuxt.hook('ready', async (nuxt) => {
  // Restart in 12 secs
  setTimeout(() => {
    console.log('Restarting in the 12 secs..')
    nuxt.callHook('restart', {hard: true})
  }, 12000)
})

Thanks for looking into this. If you require any more info, please let m eknow.

Updated reproduction to latest (3.8) using npx nuxi upgrade --force. Same issue even when running with npx nuxi-edge@latest dev.

Same issue with the next plugin:

import mongoose from "mongoose";
import { createTunnel, type ServerOptions } from "tunnel-ssh";

export const connections: { name: string; connection: mongoose.Connection }[] = [];

export default defineNitroPlugin(async (nitro) => {
  console.log("Loading Mongoose plugin...");

  nitro.hooks.hook("request", (event) => {
    console.log("on request ", event.path);
  });

  const config = useRuntimeConfig();

  try {
    const tunnelOptions = { autoClose: false };

    const sshOptions = {
      host: process.env.SSH_HOST,
      port: 22,
      username: process.env.SSH_USERNAME,
      password: process.env.SSH_PASSWORD,
    };

    const serverOptions: ServerOptions = { port: 27017 };

    const forwardOptions = {
      dstAddr: "127.0.0.1",
      dstPort: 27017,
    };

    const [Server, Client] = await createTunnel(tunnelOptions, serverOptions, sshOptions, forwardOptions)
      .then((result) => {
        console.log("Tunnel created successfully");
        return result;
      })
      .catch((err) => {
        console.error("Error creating tunnel", err);
        throw err;
      });

    Client.on("error", (err) => {
      console.error("SSH Client error", err);
    });

    Server.on("error", (err) => {
      console.error("SSH Server error", err);
    });

    const dbs = Object.keys(config).filter(key => key.includes("MongoUri"));

    dbs.forEach((db) => {
      const connection = mongoose.createConnection(config[db] as string);
      connections.push({
        name: db.split("MongoUri")[0],
        connection,
      });

      connection.on("connected", () => {
        console.log(`Connected to ${db} MongoDB`);
      });
    });

    nitro.hooks.hookOnce("close", () => {
      for (const { connection } of connections) {
        if (connection.readyState === 1) {
          connection.close();
        }
      }

      console.log("Disconnected from MongoDB connections");

      Server.close();
      Client.destroy();
      console.log("Closed SSH tunnel");
    });
  }
  catch (error) {
    console.error("Error connecting to MongoDB ", error);
  }
});

Is it possible to keep the connection open while HMR restarts? If not, how can I close and open the connection without getting this error?

Updated reproduction to latest (3.11) using npx nuxi upgrade --force, and manually updated package.json (for those changes to the starter template). Same issue even when running with npx nuxi-edge@latest dev.

Also, apart from HMR break, and connection loss, I can notice the same disconnection issue with nuxt devtools too.

Updated reproduction to latest (3.13.0) using npx nuxi upgrade --force, and removed vue & vue-router from package.json as they not required to be added explicitly anymore.

Same issue even when running with npx nuxi-edge@latest dev. Thanks for looking into this, let me know if you require any more info.

Updated reproduction to latest (4.0.3) using npx nuxt upgrade --dedupe.

Same issue even when running with npx nuxi-edge@latest dev.

@danielroe , sorry to tag you, this reproduction is almost 2 years old. HMR still breaks on nuxt restart (2nd restart) where the [unhandledRejection] connect ECONNREFUSED error is still thrown, even after #1000 / #1001
