URL Pattern API Documentation: Syntax and Usage for URL Pattern Matching

Summary

The article provides documentation for the URL Pattern API, a web API that defines a syntax for creating URL pattern matchers. It explains that patterns are specified using the URLPattern interface and are based on the path-to-regexp JavaScript library syntax, similar to Ruby on Rails. The API allows patterns to contain capturing groups that extract parts of matched URLs, and patterns can be matched against full URLs or individual URL components. The content covers concepts, usage, interfaces, and pattern syntax details.
