<baseline-status> web component

A widget displaying Baseline status of a web feature based on https://github.com/web-platform-dx/web-features data

Example

Show Baseline status widget for anchor-positioning:

<baseline-status featureId="anchor-positioning"></baseline-status>

Data source

The widget fetches data from the Web Features API endpoint: https://api.webstatus.dev/v1/features/ which exposes data from the web-platform-dx/web-features project.

Feature IDs come from the github.com/web-platform-dx/web-features repo.

Alternatively, you can find the feature ID by browsing the webstatus.dev site and reading the ID from the URL. E.g. for Intl.ListFormat feature the page URL is https://webstatus.dev/features/intl-list-format, so the ID for this feature is intl-list-format.

Usage

Option 1. Install and bundle with your application

Install

npm install baseline-status

See docs for example usage in HTML.

See rollup.config.js for an example of a bundler configuration.

Option 2: Precompiled from e.g. CDN.

This method is less optimal from performance perspective, as it can introduce multiple versions of Lit into your application since npm can't deduplicate the packages Learn more.

It can be used for quick testing and prototyping.

<script src="https://cdn.jsdelivr.net/npm/baseline-status@1/baseline-status.min.js" type="module"></script>
<baseline-status featureId="anchor-positioning"></baseline-status>
