Optimize Toolset

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.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

vite-plugin-console-forward

Forward browser console logs to your terminal during Vite development.

Installation

bun add -d vite-plugin-console-forward

Usage

// vite.config.ts
import consoleForward from "vite-plugin-console-forward";

export default {
  plugins: [consoleForward()],
};

Options

consoleForward({
  levels: ["log", "warn", "error", "info", "debug"],
  captureErrors: true,
  captureRejections: true,
  prefix: "browser",
});

Example Output

[browser:debug] [vite] hot updated: /src/components/HelloWorld.vue
[browser:log] some console.log for testing HMR
[browser:warn] This is a console.warn for testing HMR
[browser:error] {
  "message": "Error: This is a test error for HMR!",
  "filename": "http://localhost:5173/src/components/HelloWorld.vue",
  "lineno": 13,
  "colno": 10
}

How It Works

This plugin uses Vite's HMR (Hot Module Replacement) WebSocket connection to forward browser console output to your terminal.

Architecture

  1. Client-side injection: The plugin injects a virtual module into your app's <head> that:

    • Wraps native console methods (log, warn, error, etc.) to intercept calls
    • Listens for window.onerror and unhandledrejection events
    • Serializes arguments (handling circular references, errors, and nested objects)
    • Sends messages through Vite's import.meta.hot.send() API

  2. Server-side handling: The Vite dev server:

    • Listens for console-forward WebSocket events
    • Formats and prints messages to your terminal with the configured prefix

  3. HMR-aware: The client code:

    • Tracks WebSocket connection state to avoid errors when disconnected
    • Properly cleans up event listeners and restores original console methods on HMR dispose

Key Implementation Details

  • Uses a virtual module (virtual:console-forward) to inject client code
  • Only active during development (apply: "serve")
  • Prevents infinite loops when console methods are called during forwarding
  • Limits serialization depth to 10 levels to avoid performance issues
