web-features: exploring the set of interoperable features of the web platform

By the W3C WebDX Community Group and contributors.

web-features is an effort to build a shared catalog of features of the web platform. By creating a common list of features and their definitions, web-features aims to improve understanding of what web developers get and want from the web. web-features does this by:

• Creating feature definitions, which identify and describe capabilities of the web
• Generating Baseline support data, which summarizes the availability of web features across key browsers and releases
• Publishing the web-features npm package, which bundles feature identifiers with Baseline statuses

From Array to Cascade Layers to Offscreen Canvas, web-features identifies, defines, and categorizes capabilities of the web platform that web developers care about. By creating a common nomenclature for web platform features, web-features intends to support communication between web developers, browser vendors, standardization bodies, and other ecosystem participants.

Get started

To get feature identifiers, Baseline support data, or cross-references to other resources (such as specifications and caniuse), use the web-features npm package. Read the package README for more information.
