Hello,

While working on my project, I often have that error leading most of the time to the server to stop :

 ERROR  [unhandledRejection] read ECONNRESET                                                                                                                     8:02:41 AM

It's always during the HMR, specially if I modify a little too fast while it's already reloading. Never had it in production.

Might be important to add that I use nuxt exclusively as a frontend, I don't have a server/ folder.

thanks 🙂

Hi @ashen zinc. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The ECONNREFUSED and ECONNRESET errors you’re encountering during Hot Module Replacement (HMR) in Nuxt development are not uncommon, especially when making rapid changes that trigger multiple reloads. While the knowledge sources do not provide a direct, explicit solution for these specific errors, they do highlight several related HMR and development server issues that may help you troubleshoot:

  1. HMR Instability and Performance Issues: On Windows, HMR can be particularly slow or unstable, sometimes causing multiple reloads or long reload times. The Nuxt team recommends using WSL (Windows Subsystem for Linux) with a Linux distribution like Ubuntu to significantly improve HMR performance and stability. This setup can reduce reload times and avoid multiple restarts, which might help mitigate the connection errors you’re seeing if you’re on Windows docs: improve HMR performance note for Windows users.

  2. HMR and Dev Server Protocols: If you’re running your dev server behind a proxy or using custom Vite HMR settings, protocol mismatches (ws/wss) can cause connection issues. Letting Vite decide the protocol by default is recommended, unless you have a specific need to override it fix(vite): don't force hmr protocol if devServer.https is disabled.

#

  1. HMR Bugs and Fixes: There have been several recent fixes in Nuxt related to HMR, including improvements to route and template updates, and handling of custom routes and app config during HMR. If you’re not on the latest Nuxt 3 version, consider upgrading, as some HMR-related bugs have been resolved in recent releases fix(nuxt,vite): support hmr for templates, pages and page metadata, fix(nuxt): track + re-add custom routes on hmr, fix(nuxt): delete existing properties on app config template's HMR.

  2. Rapid File Changes: Making changes too quickly while HMR is still processing can sometimes overwhelm the dev server, leading to connection resets or refusals. This is a known pain point, but the sources do not provide a direct workaround other than to avoid making rapid consecutive changes.

  3. No server/ Directory: Using Nuxt as a frontend-only app (without a server/ directory) is supported, and should not inherently cause these errors.

Summary:
While there is no explicit fix for the ECONNREFUSED/ECONNRESET errors during HMR in the provided sources, upgrading Nuxt, using WSL on Windows, and ensuring your HMR/Vite configuration is standard are recommended steps. If the problem persists, it may be due to limitations or bugs in the current HMR implementation, which the Nuxt team continues to improve.

If you have a reproducible case, consider checking for open issues or reporting it on the Nuxt GitHub, as ongoing HMR improvements are being made.

Let me know if you need more targeted troubleshooting steps!
