v1.0.0-RC.6

This release contains a syntax change to attributes that must be addressed manually before updating.

The recommended CDN link for Datastar is now version-locked to ensure safer updates and to avoid serving outdated cached files:

<script type="module" src="https://cdn.jsdelivr.net/gh/starfederation/[email protected]/bundles/datastar.js"></script>

Breaking changes:

• The attribute key delimiter has been changed from - to : (data-signals-foo becomes data-signals:foo, data-on-click becomes data-on:click, etc.), as allowed by the HTML Standard. The following regular expression can be used to update attributes.
  • Search: data-(?!(on-(intersect|interval|load|raf|resize|signal-patch|signal-patch-filter)(_|=)))(attr|bind|class|computed|indicator|on|persist|ref|signals|style)-
  • Replace: data-$4:
• Renamed the data-on-load attribute to data-init.
• Renamed .trail and .notrail modifier arguments to .trailing and .notrailing respectively.
• Removed file upload progress monitoring from Datastar Pro, which had limited browser support. It is recommended to use a file upload library instead, or wait for Rocket which will include a file upload web component. (#1049)
• Fetch requests are now cancelled when the element that initiated them is removed from the DOM. (#1045)
• The data-bind attribute on an input with type file now only creates one signal instead of {signalName}, {signalName}Names, and {signalName}Mimes. The resultant type of the signal is {name: string, contents: string, mime: string}[]. (#1041)
• Camel casing no longer capitalizes after a number, and kebab casing now only preserves what was written in the attribute key (data-signals:a2b--foo__case.kebab makes $a2b--foo instead of $a-2-b-foo). (#1030)

Non-breaking changes:

• Datastar now supports all browsers that have support for ES2021. (#1037)
• Added support for using object syntax with the data-computed attribute. (#1053)
• The data-indicator attribute now sets the signal to false even if the signal has already been defined.
• Fetch requests now respect URIs provided by a base tag. (#1047)
• Form fields are no longer validated if a novalidate attribute exists on the form tag. (#1056)
• Setting a signal to null or undefined now actually deletes the signal. (#1058)
• Attributes can now be used on the html element.
• Attribute keys and aliases can now start with a non-letter (data-signals:1foo or data-on:-foo). (#1030)
• Fixed a bug in data-bind when using namespaced signals as arrays.
• Fixed a bug resulting in data-ignore__self not being applied. (#1064)
• Fixed a bug preventing the __debounce.leading modifier from working.
• Fixed a bug preventing the combination of __debounce and __viewtransition modifiers from working.
• Fixed a bug when using auto request cancellation where the FINISHED fetch event would fire after the STARTED fetch event of the cancelling request.
