Specification

Summary

Add a `URLPatternList` primitive to efficiently match URLs against a collection of `URLPattern` objects.

Blink component

Blink>URLPattern

Motivation

URL routing use cases need to match an incoming URL against a potentially large number of patterns. Using an array of URLPattern objects that are checked sequentially is not efficient. An object representing a list of patterns can perform more efficient matching by using internal data structures that take advantage of commonalities between patterns in the list.
