A TypeScript library that converts path strings like `/user/:name` into regular expressions for route matching. It supports named parameters, wildcards, optional segments, and reverse compilation of paths from parameters.

Use cases

• match url paths with named parameters like /user/:name
• convert route patterns to regular expressions
• extract route params from a url path
• build a router with wildcard and optional path segments
• generate url paths from route templates and params
• validate whether a path matches a route pattern

When to choose

• you need express-style path matching in a nodejs router or framework
• you want to parse parameters from ordered path strings
• you need to compile parameterized paths back into url strings

When to avoid

• you need to match query strings or arbitrarily ordered url data
• you need a full-featured router rather than a path-matching utility
• you are not working with path-like ordered strings
