path-to-regexp

Important: This release switches the package to ESM only and node >= 22. The primary incompatible API change is to switch ambiguous matches (2+ parameters in a segment) from the first being greedy to the last. For example:

const input = "/foo.json.html";
const fn = match("/:file.:ext");

fn(input); //=> ["foo", "json.html"]

In the v8 this would have output ["foo.json", "html"]. Making the last parameter and wildcard greedy can improve performance of the regular expressions and makes it easier to build non-regex based versions of the matcher.

Changed

• Avoid duplicate trailing delimiter matches

  • A path that explicitly provided the trailing delimiter (e.g. /foo/) will no longer append an extra optional delimiter

• Refactor matching to be non-greedy

• Build project as ESM

• Remove TokenData class and Keys type

Fixed

• Reject an empty-string param in compile

• Reject wildcard array that compiles to an empty path

• Fix stringify of param names with control characters

• Quote param names followed by astral ID_Continue text

• Fix stringify lookahead across empty text tokens
