Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

  • Added the performUpdate method to allow control of update timing (#290).
  • Updates deferred until first connection (#258).

Changed

  • [Breaking] Changes property options to add converter. This option works the same as the previous type option except that the converter methods now also get type as the second argument. This effectively changes type to be a hint for the converter. A default converter is used if none is provided and it now supports Boolean, String, Number, Object, and Array (#264).
  • [Breaking] Numbers and strings now become null if their reflected attribute is removed (lit#264)).
  • [Breaking] Previously, when an attribute changed as a result of a reflecting property changing, the property was prevented from mutating again as can happen when a custom converter is used. Now, the oppose is also true. When a property changes as a result of an attribute changing, the attribute is prevented from mutating again (lit#264))

Fixed

  • [Breaking] User defined accessors are now wrapped to enable better composition (#286)
  • Type for eventOptions decorator now properly includes passive and once options (#325)

[0.6.5] - 2018-12-13

Changed:

  • Use lit-html 1.0 release candidate.

Fixed

  • Types for the property and customElement decorators updated (#288 and #291).
  • Docs updated.

[0.6.4] - 2018-11-30

Changed

  • Update lit-html dependency to ^0.14.0 (#324).

[0.6.3] - 2018-11-08

Changed

  • Update lit-html dependency to ^0.13.0 (#298).

[0.6.2] - 2018-10-05

Changed

  • LitElement changed to a non-abstract class to be more compatible with the JavaScript mixin pattern (#227).
  • Update lit-html dependency to ^0.12.0 (#244).
  • Passes the component's this reference to lit-html as the eventContext, allowing unbound event listener methods (#244).

Added

  • A disconnectedCallback() method was added to UpdatingElement (#213).
  • Added @eventOptions() decorator for setting event listener options on methods (#244).

[0.6.1] - 2018-09-17

Fixed

  • Fixes part rendering and css custom properties issues introduced with lit-html 0.11.3 by updating to 0.11.4 (lit#202).

Removed

  • Removed custom_typings for Polymer as they are no longer needed (lit#186).

[0.6.0] - 2018-09-13

Added

  • Added @query(), @queryAll(), and @customElement decorators (#159)

Changed

  • Significantly changed update/render lifecycle and property API. Render lifecycle is now requestUpdate, shouldUpdate, update, render, firstUpdated (first time only), updated, updateComplete. Property options are now {attribute, reflect, type, hasChanged}. Properties may be defined in a static get properties or using the @property decorator. (lit#132).

Removed

  • Removed render helpers classString and styleString. Similar directives (classMap and styleMap) have been added to lit-html and should be used instead (lit#165 and lit/lit#486).

Fixed

  • The npm run checksize command should now return the correct minified size (lit#153).
  • The firstUpdated method should now always be called the first time the element updates, even if shouldUpdate initially returned false (lit#173).
