v0.21.0

[delaneyj]

We’ve overhauled Datastar in v0.21.0, doubling down on making nestable signals declarative. To that end, we’ve removed special characters, made the API more explicit and consistent, and fixed some restrictions to nested signals that we discovered. Signal values are now accessed in expressions using the syntax signalName.value, actions no longer have a prefix, and attribute keys support nested signals using dot-delimited paths.

Added

• Added the ability to merge one-off signals using the syntax data-signals-foo="value".
• Added the ability to use dot-delimited paths to denote nested signals in applicable attribute keys (data-signals-foo.bar="value").
• Added the ability to use multiple attributes using the syntax data-attributes="{attrName1: value1, attrName2: value2}".
• Added the ability to use a single classes using the syntax data-class-hidden="foo.value".
• Added the ability to use a key instead of a value to denote a signal name in the data-bind, data-indicator and data-ref attributes (data-bind-foo, data-indicator-foo, data-ref-foo).
• Added error codes and links to descriptions in the console for every error thrown.

Changed

• Signals no longer have the $ prefix and must be acessed using a .value suffix (signalName.value).
• Action plugins no longer have the $ prefix.
• Renamed the data-store attribute to data-signals.
• Renamed the data-bind attribute to data-attributes.
• Renamed the data-model attribute to data-bind.
• Changed the data-* attribute modifier delimiter from . to : (data-on-keydown:debounce_100ms:throttle_lead="value").
• The the get(), post(), put(), and delete() plugins have been replaced by a single sse() plugin that accepts the method as an option (sse(url, {method="get"})).
• The setAll() and toggleAll plugins now accept a dot-delimited path format, instead of a regular expression.

Fixed

• Fixed headers not merging correctly.
• Fixed new lines in the SDK protocol for paths.
