v2.0.1

Improved:

• Small performance improvement by incrementing = index while parsing set-cookie (#280)

v2.0.0

Important: This release moves the package to ESM only. In node 22+ you can require(esm), and older node versions are not supported.

Changed

• Switch to ESM (#273)
• Remove deprecated code paths (#272)
  • The old parse and stringify methods have been renamed: parseCookie and stringifySetCookie
  • stringifySetCookie only supports object mode (e.g. { name: "", value: "" })

Improvements

• Faster stringify cookie (#262)
• Optimize encode performance (#269)
• Apply encode to empty cookie values (#277)

Fixed

• Omit leading semicolon when stringifying cookies with skipped values (#267)

v1.1.1

Fixed

• Overwrite value in passed in options (#253) c66147c
  • When value was provided in serialize(key, value, { value }) the value in options was used instead of the value passed as an argument
