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 🙏

@enhance-eng/sandbox

v0.7.1

Published

Enhance preview bootstrap and tooling package.

Readme

@enhance-eng/sandbox

Enhance sandbox library for adding preview functionality to your application.

Supported frameworks: React SPAs, Next.js (App Router), and statically generated sites.

Installation

npm install @enhance-eng/sandbox

Next.js (App Router)

Generate the service worker file, then add the EnhanceScripts component to your root layout.

Step 1: Generate the service worker:

npx enhance-sandbox init --publishable-key pk_your_key

This writes public/enhance-sw.js. Commit the file to your repository.

Step 2: Add the component to your root layout:

// app/layout.tsx
import { EnhanceScripts } from "@enhance-eng/sandbox/next";

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <head>
        <EnhanceScripts />
      </head>
      <body>{children}</body>
    </html>
  );
}

The EnhanceScripts component registers the service worker, bootstraps the overlay, and renders scripts natively so React hydrates without mismatch errors.

Vite

Add the plugin to your Vite config:

// vite.config.ts
import { defineConfig } from "vite";
import { enhance } from "@enhance-eng/sandbox/vite";

export default defineConfig({
  plugins: [
    enhance({
      publishableKey: "pk_your_key",
    }),
  ],
});

The plugin generates the service worker, serves it in dev, emits it as a build asset, and injects the registration script automatically.

Other Build Tools

For non-Vite, non-Next.js setups, generate the service worker with the CLI, then register it in your app.

Step 1: Generate the service worker:

npx enhance-sandbox init --publishable-key pk_your_key

Step 2: Register it in your application entry point:

import { enhance } from "@enhance-eng/sandbox";

enhance();

Existing Service Worker

If your app already uses a service worker (e.g. for offline support or caching), pass its URL with the serviceWorker option so Enhance registers only during playground sessions and falls back to your service worker for normal visitors.

Vite:

enhance({ publishableKey: "pk_your_key", serviceWorker: "/sw.js" });

Next.js:

<EnhanceScripts serviceWorker="/sw.js" />

Other:

enhance({ serviceWorker: "/sw.js" });
