I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Hot-reload bridge for Vite Module Federation hosts and remotes

vite-mfe-host-reloader

🔄 Reload the host application automatically when any micro-frontend remote changes during development.

vite-mfe-host-reloader is a Vite plugin built for micro-frontend architectures where multiple Vite dev servers (host + remotes) run in parallel.

When a remote (submodule) changes, the plugin notifies the host via WebSockets, triggering a full reload of the host app — no more manual browser refreshes.

Why this plugin exists

In most micro-frontend setups:

The host runs on one Vite dev server
Each remote/module runs on its own Vite dev server
Updating a remote does not automatically reload the host

This results in:

constant manual refreshes
broken development flow
confusion when changes don’t reflect immediately

vite-mfe-host-reloader solves this by creating a lightweight WebSocket bridge between remotes and the host.

Features

Reloads host when any remote changes
Supports multiple remotes
Works with Vite + Module Federation
Compatible with Vite 4, 5, 6, 7
Fully ESM-safe
pnpm-safe (no symlink hacks)
Dev-only (zero production impact)

Installation

npm install vite-mfe-host-reloader --save-dev
# or
pnpm add vite-mfe-host-reloader -D
# or
yarn add vite-mfe-host-reloader -D
