Publish, ship, and install modern JavaScript for faster applications

Modern JavaScript offers size and performance improvements over transpiled ES5, and is supported in 95% of web browsers. Enabling modern JavaScript output brings these benefits to your application, but the impact is limited by dependencies that are already transpiled to ES5. This guide demonstrates how to publish modern packages to npm, and how to install and optimally bundle modern JavaScript packages.

CSS aspect-ratio

And it was released yesterday! The big news for us in CSS Land is that the new release supports the aspect-ratio property. This comes right on the heels.

Transitioning to modern JavaScript

Over 90% of web traffic comes from browsers that support modern JavaScript, yet most websites ship legacy syntax in order to support a small number of very old browsers.

We now have the ability to deliver modern and legacy code to browsers based on what they support, but this doesn’t extend to the large amount of dependency code in our applications. Our dependencies are still published as verbose legacy syntax in order to support the lowest common denominator of browsers today.

Beyond fast with new performance features

A whirlwind tour of new features and proposals to improve the performance of your pages.

New in Chrome 88: Manifest v3, aspect-ratio, digital goods API, and more!

Chrome 88 is rolling out now! You can now upload extensions using manifest v 3 to the Chrome Web Store. The aspect-ratio CSS property makes it easy to set the aspect ratio on any element. You can now use Play Billing in your Trusted Web Activity, and there’s plenty more.

Useful GitHub repositories


Run your GitHub Actions locally! Why would you want to do this? Two reasons:

  • Fast Feedback — Rather than having to commit/push every time you want to test out the changes you are making to your .github/workflows/ files (or for any changes to embedded GitHub actions), you can use act to run the actions locally. The environment variables and filesystem are all configured to match what GitHub provides.
  • Local Task Runner — I love make. However, I also hate repeating myself. With act, you can use the GitHub Actions defined in your .github/workflows/ to replace your Makefile!
