ractive - npm Package Versions

• Resolve a parent context above a reference expression will now work correctly.

• Event handlers with auto-linked argument paths that are only referenced from the handler will now ensure that they have a runloop to avoid throwing.

Bug fixes

• Embedded typings are improved: added missing methods and properties and improved extend support.
• yields in non-isolated components will avoid creating implicit mappings by properly skipping the component fragment to the container fragment when resolving references (#3351).
• Components initialized from a template will now call the component constructor. There's a new component: boolean property on init options passed to the constructor that is set to true when the view is initilizing the component. This also avoids double init.
• An event handler removed while firing will no longer throw.
• Context find methods now support the options that the instance versions support.
• Custom elements are now checked in a hopefully more cross-browser way.
• Links will now propagate changes that happen in their source models up to their parent model.
• Computations that have a dependency that causes the computation to invalidate while computing will no longer get stuck, as the change notification will be passed through even though the computation is currently computing. (#3380)
• Elements with no attributes will no longer throw during render if they happen to be transitioned.
• Custom events that are torn down before they have a chance to fully render will no longer throw.
• Virtual get and set with deep try to do the right thing with Dates. (#3388)
• Computeds that get computed during a link will no resolve the correct dependency.
• Swapping an element with splice will now properly notify upstream paths.

Experimental new features

• Computation setter functions now receive a context argument, and both getter and setter functions now receive a keypath argument.
• Component styles can be split into multiple managed style tags in the document head by setting Ractive.perComponentStyleElements to true.
• Methods that set a single value will now return the new value as the resolution of the returned promise e.g. r.toggle('foo') if foo is falsey will return a promise that resolves to true. add/subtract/set behave similarly.
• Decorators and custom events can now access their local context, in the case of a yielded attribute partial, with this.getLocalContext().
• Delegated events now proxy stopPropagation, stopImmediatePropagation, and preventDefault to behave a bit more like a non-delegated event would be expected act.
• If you need to have precise control over whitespace handling in a template, particularly around additional lines that only have block tags, you can use a new parser flag preserveStandaloneSections in addition to a - trailing sigil in the mustache to consume all of the whitespace around the tag, effectively removing its line from the output. This is modelled on the on similar Liquid functionality. (#3338)
