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 🙏

Nice features

  • Show multiple notifications simultaneously, and/or
  • Hide older notifications before showing one or more new notifications.
  • Great accessibility.
  • Is a compact ES module.

Skip to Instance options to get a complete overview of all features!

Usage

For this example I assume the main JavaScript file is processed by a module bundler that can process CSS files.

# Install package from npm
npm install @codebundlesbyvik/simple-notifier

If you're not using a module bundler then:

For the example below I assume the main JavaScript file is processed by a module bundler.

/* style.css */
@import "@codebundlesbyvik/simple-notifier";
// index.js
import "./style.css";
import SimpleNotifier from "@codebundlesbyvik/simple-notifier";

const notifier = new SimpleNotifier();

// The following element is inserted as the first child of <body>:
// <div class="simple-notifier simple-notifier--position-y-start simple-notifier--position-x-center">
// </div>

const text = "This is an example notification.";
const variant = "success";

notifier.show(text, variant);

// Notification is shown for 4000 ms.

Browser support

Requires an ECMAScript 2022 (ES13) compatible browser. Practically speaking, all browsers released in 2021 and onwards are fully supported.

.hide(id: number)

.hideAll()

Hide all currently shown notifications.

.currentId

Get the current ID, i.e. the one that'll be used for the next notification.

.ids

Get the IDs of all currently shown notifications.

Events

Events are fired on the instance element .simple-notifier. The detail property contains the id of the notification it was fired for.

| Event | Fired after... | | :---------- | :--------------------------------- | | shown | Notification is shown. | | hidden | Notification is hidden. | | allhidden | Last shown notification is hidden. |

Upgrading from 2.x.x

The following changes are breaking:

  • Removed: instanceId
  • Renamed: notificationId > id. Effects getters & event detail.
  • Renamed: dismissable > dismissible
  • Changed: Use logical directional keywords instead of physical keywords, i.e. left > start.
  • Changed: notificationOptions.titleLevel must now be provided as notificationOptions.title.el (see NotificationOptions).
  • Changed: If variant is provided both as .show() parameter and as notificationOptions.variant, .show() now takes preference.
  • Changed: Undocumented but public class field names, visibility & mutability.
