The Web Platform Status dashboard helps developers understand the interoperability of web features through clear tagging of their Baseline status—but knowing the moment a feature becomes interoperable takes effort. You must check the dashboard periodically to see if a feature becomes Baseline, or discover it elsewhere. This delays adoption, and you might forget.
With Baseline Alerts added to the dashboard, you can be notified about changes in the web features you care about. This feature is more than convenient: It lessens the time between awareness of a feature and adoption of it.
How do Baseline Alerts work?
Go to the Web Platform Status dashboard and sign in with GitHub. After you sign in, a Subscriptions button appears.
- On the home page, you can subscribe to all features.
- On an individual feature's page—such as JPEG XL, for example—you can subscribe to updates for that feature.
- On a saved search page, such as for all CSS features, you can subscribe to updates for the features in that search.
The Subscriptions dialog lets you choose the notifications you want and the frequency:
A subscription can trigger an email notification or update a custom RSS feed when features:
- Become Widely available
- Become Newly available
- Get a new browser implementation
- Regress to limited availability
You can opt to receive these changes every month, week, or every time the underlying feature changes. Once subscribed, manage your subscription by selecting the Subscriptions menu item.
How are Baseline Alerts useful?
Baseline Alerts let you receive email notifications about web feature status, but you can also use them for other tasks.
Create a personalized newsletter
Baseline Alerts are useful because you can scope them to the features you care
about. This lets you create a personalized newsletter for specific features. For
example, you can list all HTML web features with the group:html query. From
the results page, save the search.
Once the search is saved, you'll be able to subscribe to updates to its features.
In this example, you'd get an alert every time an HTML feature becomes Baseline Newly available or Widely available. The query syntax for the Web Platform Status dashboard is also more flexible than for just groups. You can save a search for any query you can come up with and create a custom feature set for which you can receive notifications. For more information, see the query grammar.
Create shareable lists
You can also share saved searches. You can do this using the URL—which is viewable by anyone who has it—or you can generate a QR code for that page. Select the share icon on the saved search page.
This is useful for content creators and web influencers, who can share a list of features with their audience in videos and conference talks. It gives your audience a way to get in-depth information about the features you want them to use.
Slack webhooks
If you run a Slack channel, you can use Baseline Alerts to send feature updates to a Slack webhook URL. To do this, select Notification channels in the left-hand menu, and you'll see a section labeled Webhook. From there, you can add a Slack webhook URL and give it a name. Once you've added it, you can set it as a notification target when you subscribe to features.
In the future, we hope to expand this feature so that webhooks can be used across more services, such as creation of issues on GitHub, and other useful development tools.
Give it a try!
Baseline Alerts accelerate the discovery of interoperable features so you can begin developing with them sooner. To provide feedback, file an issue on the webstatus.dev GitHub repository.
