New URLPattern API brings improved pattern matching to Node.js and Cloudflare Workers

Cloudflare announces its contribution of a standards-compliant URLPattern API implementation to Node.js (via Ada URL), enhancing consistency across web-interoperable runtimes such as Workers, Node.js, Deno, and others. The post explains URLPattern’s capabilities for URL routing and matching, shares code examples, notes collaborations with browser teams to resolve spec/test inconsistencies, and provides guidance on where URLPattern is available today (browsers, Cloudflare Workers, Node.js v23.8.0, NativeScript, Deno). It also previews future performance improvements and proposals like URLPatternList to further optimize server-side routing.
