Heads up! This is a fairly large change (again) and I need to apologize in advance. If I foresaw what this version would have ended up being I would not have released version 7. A longer blog post and explanation will be incoming this week, but the pivot has been due to work on Express.js v5 and this will the finalized syntax used in Express moving forward.

Added

• Adds key names to wildcards using *name syntax, aligns with : behavior but using an asterisk instead

Changed

• Removes group suffixes of ?, , and * - only optional exists moving forward (use wildcards for , {*foo} for *)
• Parameter names follow JS identifier rules and allow unicode characters

Added

• Parameter names can now be quoted, e.g. :"foo-bar"

Removed

• Removes loose mode
• Removes regular expression overrides of parameters

v7.1.0...v8.0.0

Fixed

• Add backtrack protection to parameters 29b96b4
  • This will break some edge cases but should improve performance

v0.1.9...v0.1.10

Added

• Allow a non-lookahead regex (#312) c4272e4

component/path-to-regexp@v0.1.8...v0.1.9

Added

• Adds a strict option to detect potential ReDOS issues

Fixed

• Fixes separator to default to suffix prefix when not specified
• Allows separator to be undefined in TokenData
  • This is only relevant if you are building TokenData manually, previously parse filled it in automatically

Comments

• I highly recommend enabling strict: true and I'm probably releasing a V8 with it enabled by default ASAP as a necessary security mitigation

v7.0.0...v7.1.0

Hi all! There's a few major breaking changes in this release so read carefully.

Breaking changes:

• The function returned by compile only accepts strings as values (i.e. no numbers, use String(value) before compiling a path)
  • For repeated values, when encode !== false, it must be an array of strings
• Parameter names can contain all unicode identifier characters (defined as regex \p{XID_Continue}).
• Modifiers (?, *, ) must be used after a param explicitly wrapped in {}
  • No more implied prefix of / or .
• No support for arrays or regexes as inputs
• The wildcard (standalone *) has been added back and matches Express.js expected behavior
• Removed endsWith option
• Renamed strict: true to trailing: false
• Reserved ;, ,, !, and @ for future use-cases
• Removed tokensToRegexp, tokensToFunction and regexpToFunction in favor of simplifying exports
• Enable a "loose" mode by default, so / can be repeated multiple times in a matched path (i.e. /foo works like //foo, etc)
• encode and decode no longer receive the token as the second parameter
• Removed the ESM CommonJS dual package in favor of only one CommonJS supported export
• Minimum JS support for ES2020 (previous ES2015)
• Encode defaults to encodeURIComponent and decode defaults to decodeURIComponent

Added:

• Adds encodePath to fix an issue around encode being used for both path and parameters (the path and parameter should be encoded slightly differently)
• Adds loose as an option to support arbitrarily matching the delimiter in paths, e.g. foo/bar and foo///bar should work the same
• Allow encode and decode to be set to false which skips all processing of the parameters input/output
• All remaining methods support TokenData (exported, returned by parse) as input
  • This should be useful if you are programmatically building paths to match or want to avoid parsing multiple times

Requests for feedback:

• Requiring {} is an obvious drawback but I'm seeking feedback on whether it helps make path behavior clearer
  • Related: Removing / and . as implicit prefixes
• Removing array and regex support is to reduce the overall package size for things many users don't need
• Unicode IDs are added to align more closely with browser URLPattern behavior, which uses JS identifiers
