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

event-target-shim-es5

npm version Node.js CI

This package is based on event-target-shim. Although the original package contains an ES5 bundle, it did not contains an ES5 module. Importing the module directly or indirectly may break web apps running on ES5 browsers.

On install, this package will transpile your version of event-target-shim to make it compatible with ES5 browsers.

Package authors should consider importing this package instead of event-target-shim, so your packages will not break your users due to having event-target-shim as a transient dependency.

How to use

To install in your project, run:

npm install event-target-shim event-target-shim-es5

In your code:

import EventTarget, { defineEventAttribute } from 'event-target-shim-es5';

class YourComponent extends EventTarget {
  handleClick() {
    this.dispatchEvent(new Event('click'));
  }
}

defineEventAttribute(YourComponent.prototype, 'click');

How it works

On postinstall, this package will run Babel and Webpack to transpile event-target-shim into a single file.

This package peer-depends on event-target-shim. Thus, you can select your own version of event-target-shim.

Updating event-target-shim

When you update event-target-shim, re-run npm install event-target-shim-es5 to get the latest package transpiled.

Alternatives

Instead of importing this package, there are alternative workarounds you can use.

Including the source code

You can copy the source code of event-target-shim into your web app and use your build pipeline transpile the original package.

When copying, be sure to include the original license and continue to depends on the package to make sure npm audit will scan for vulnerabilities.

Modify your bundler configuration

Webpack do not transpile code under /node_modules/ unless specified explicitly. You can modify webpack.config.js to include /node_modules/event-target-shim/ and use babel-loader to transpile it on-the-fly.
