ES2015 Set and Map

Improved

• ES2015 set/map usage, removes a few bytes 3fe91cc

v5.0.0...v5.0.1

ESM only

Changed

• This package is now ESM only! Do not upgrade if you aren't using ESM or a compatible bundler.
• Style properties are no longer sorted (fixes #105).

Improvements

• Shrunk the package 0.1kb (7% smaller).
• Performance improved in large style benchmarks by ~5%.

Added

• Added a compile API for pre-compiling styles to add to multiple sheets.
• Added support for a custom prefix to create() so all styles can be namespaced in a single sheet.

v4.1.0...v5.0.0

Allow null and undefined in `PropertyValue`

Changed

• Allow null and undefined in PropertyValue f6b33f9
  • Primarily means that an array of values can now contain null and undefined and they will be filtered out as if they weren't set

Remove `register*` Methods

Changed

• Remove old register* methods b506c8b
  • Everything can be done using a singular registerStyle going forward, simplifies the API interface and removes even more bytes in production!
  • If you need to provide backward-compatible interfaces (e.g. you're a library wrapping free-style), the commit above shows how it backward compatibility was maintained in 3.x - you'll just need to implement it yourself now
  • The entire bundle of free-style is down to 1.7kB https://bundlephobia.com/result?p=free-style@4.0.0

Fix Nested Selector Hashing

Fixed

• Fix nested selectors returning the same hash when no other styles are present
  • E.g. { color: 'red' } and { '&:first-child': { color: 'red' } } should return different hashes, otherwise it'll create some nasty edge cases for the class name getting set to { color: 'red' } unexpectedly

Remove \0 From Strings

Fixed

• Remove \0 from internal hash strings
• Use the internally generated hash for shorter IDs for conflict resolution

Publish ES5 Distribution

Fixed

• Add new dist.es5 directory to NPM files, left out of the previous release 😅

Add ES5 Distribution

Added

• Create an ES5 distribution available at free-style/dist.es5

Register Style For Everything

Added

• Allow registerStyle to handle every previous method in one function (e.g. registerHashRule, registerRule and registerCss)
  • This works by interpolating rules with & (e.g. @keyframes &), and adding a new flag $global: true

Even Smaller Build

Changed

• Move to ES2015 (saves 0.3kb)
• Cosmetic code changes to shave a few extra bytes
