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

webext-alert npm version

WebExtension module: alert() for background pages/workers in Web Extensions

  • Browsers: Chrome, Firefox, Safari
  • Manifest: v2 and v3
  • Contexts: All contexts

Install

You can download the standalone bundle and include it in your manifest.json.

Or use npm:

npm install webext-alert
import alert from 'webext-alert';

Usage

alert('Hello from background script!');

API

alert(message)

Uses alert() wherever possible, but falls back to a custom window with the same content.

If the native alert is used, this will block the execution of the background script until the user closes the alert.

If the custom window is used, webextAlert will return a promise that resolves when the user closes the window.

Known issues

  • If the user is using a full screen window on macOS or they're on mobile, a whole new window will be opened instead of a popup. This is a limitation of the WebExtensions API.
