The core foundations of a delightful web experience are...

  • Fast - It responds quickly to user interactions with silky smooth animations and no janky scrolling.
  • Integrated - The user doesn’t have to reach through the browser, it uses the full capabilities of the device to create an experience true to the device.
  • Reliable - Load instantly and reliably, never showing the downasaur, even in uncertain network conditions.
  • Engaging - Keeps the user coming back to the app with beautifully designed experiences that look and feel natural.

Delightful web experiences are...

Fast

Users don’t expect janky scrolling or slow load performance. Making your site fast is a process that starts with understanding how RAIL affects the performance of your site and how to use that to measure and improve your performance.

Integrated

User experiences on the web should feel like an integrated part of the user's device; instead of having to reach through a browser window, the experience should feel true to how the user interacts with the device.

Reliable

Users don’t expect the web to work without a network connect, and often don’t even bother to try when it’s a slow or intermittent connection. We need to change that perception. The web must be reliable.

Engaging

An engaging app goes beyond functional, but ensures that the whole experience is delightful making it easy for the user to do what they need to do. Using features like Web Push, it’s always up to date, and Notifications keeps users informed. It uses the right capabilities, at the right time, in a beautiful way.

What's new?

Deprecations and removals in Chrome 78

A round up of the deprecations and removals in Chrome 78 to help you plan.

Fresher service workers, by default

HTTP requests that check for updates to the service worker script will no longer be fulfilled by the HTTP cache by default. This works around a common developer pain point, in which setting an inadvertent Cache-Control: header on your service worker script could lead to delayed updates. Also, updates to imported scripts can trigger the service worker update flow.

Web Components

Web Components are a new set of standards which let you create your own HTML elements. You can use them to build anything, from simple UI elements, to entire applications.

Payment Request API

The Payment Request API is a W3C standard candidate meant to eliminate checkout forms. It improves the purchase process, provides a more consistent user experience and allows you to easily leverage different payment methods.

Credential Management API

The Credential Management API is a standards-based browser API that provides a programmatic interface between the site and the browser for seamless sign-in across devices.
