Release Notes

lit/lit (lit-element)

v4.0.2

Compare Source

Patch Changes

• #​4387 bf551b5b - Ensure renderRoot exists before first update (#​4268)

• #​4282 c7922a0c Thanks @​MaxArt2501! - Fix a bug where accessing a @query decorated field with the cache flag set before the first update would result in null being cached permanently. null will no longer be cached before the first update and in DEV_MODE now raises a warning.

• #​4388 839ca0f8 - Fixes bug where adding or removing controllers during a reactive controller lifecycle would affect the execution of other controllers (#​4266). Controllers can now be added/removed during lifecycle without affecting others.

v4.0.0

Compare Source

Major Changes

• #​3751 dfd747cf - Simplify lit-html attribute handling for standards-compliant browsers that iterate attributes in source order

• #​4254 1040f758 - Change the type of ReactiveElement.renderRoot and return type of ReactiveElement.createRenderRoot() to be HTMLElement | DocumentFragment to match each other and lit-html's render() method.

• #​4146 0f6878dc - Generated accessor for reactive properties now wrap user accessors and automatically call this.requestUpdate() in the setter. As in previous versions, users can still specify noAccessor: true, in which case they should call this.requestUpdate() themselves in the setter if they want to trigger a reactive update.

• #​3759 1db01376 - Use replaceWith() for SVG templates

• #​3750 c3e473b4 - Use toggleAttribute() to simplify boolean attribute parts

• #​3850 7e8491d4 - Delete deprecated queryAssignedNodes behavior and arguments.

  Migrate deprecated usage with a selector argument to use
  @queryAssignedElements. E.g.: @queryAssignedNodes('list', true, '.item') to
  @queryAssignedElements({slot: '', flatten: false, selector: '.item'}).

• #​3754 76795a18 - Remove UpdatingElement alias for ReactiveElement

v3.0.0

Compare Source

Major Changes

• Most users should no longer import directly from lit-element, and instead prefer importing LitElement from the lit packages. The default entry point for lit-element remains backward-compatible and includes all decorators. However, it's recommended to use import {LitElement} from 'lit'; and import decorators from lit/decorators as necessary. See the Upgrade Guide for more details.

• UpdatingElement has been moved from the lit-element package to the @lit/reactive-element package and renamed to ReactiveElement. See the ReactiveElement API documentation for more details. In addition, the source for css-tag, and all decorators have been moved to @lit/reactive-element. However, all symbols are re-exported from both lit and lit-element packages.

• The @internalProperty decorator has been renamed to @state.

• Errors that occur during the update cycle were previously squelched to allow subsequent updates to proceed normally. Now errors are re-fired asynchronously so they can be detected. Errors can be observed via an unhandledrejection event handler on window.

• The lib folder has been removed.

• Rendering of renderRoot/shadowRoot) via createRenderRoot and support for static styles has moved from LitElement to ReactiveElement.

• The createRenderRoot method is now called just before the first update rather than in the constructor. Element code can not assume the renderRoot exists before the element hasUpdated. This change was made for compatibility with SSR.

• ReactiveElement's initialize method has been removed. This work is now done in the element constructor.

• The static render has been removed.

• For consistency, renamed _getUpdateComplete to getUpdateComplete.

• When a property declaration is reflect: true and its toAttribute function returns undefined the attribute is now removed where previously it was left unchanged (#​872).

• The dirty check in attributeChangedCallback has been removed. While technically breaking, in practice it should very rarely be (#​699).

• LitElement's adoptStyles method has been removed. Styling is now adopted in createRenderRoot. This method may be overridden to customize this behavior.

• LitElement's static getStyles method has been renamed to static finalizeStyles and now takes a list of styles the user provided and returns the styles which should be used in the element. If this method is overridden to integrate into a style management system, typically the super implementation should be called.

• Removed build support for TypeScript 3.4.

• Decorators are no longer exported from the lit-element module. Instead, import any decorators you use from lit/decorators/*.

• lit-html has been updated to 2.x.

• Support for running in older browsers has been removed from the default configuration. Import the polyfill-support module to support Shady DOM. Note also that Lit parts inside <style> elements are no longer supported. See Polyfills for more details.

• For simplicity, requestUpdate no longer returns a Promise. Instead await the updateComplete Promise.

• Removed requestUpdateInternal. The requestUpdate method is now identical to this method and should be used instead.

• #​2103 15a8356d - Updates the exports field of package.json files to replace the subpath
  folder
  mapping
  syntax with an explicit list of all exported files.

  The /-suffixed syntax for subpath folder mapping originally used in these
  files is deprecated. Rather than update to the new syntax, this change replaces
  these mappings with individual entries for all exported files so that (a) users
  must import using extensions and (b) bundlers or other tools that don't resolve
  subpath folder mapping exactly as Node.js does won't break these packages'
  expectations around how they're imported.

Minor Changes

• A public renderOptions class field now exists on LitElement and can be set/overridden to modify the options passed to lit-html.
• Adds static shadowRootOptions for customizing shadowRoot options. Rather than implementing createRenderRoot, this property can be set. For example, to create a closed shadowRoot using delegates focus: static shadowRootOptions = {mode: 'closed', delegatesFocus: true}.
• Adds development mode, which can be enabled by setting the development Node exports condition. See Development and production builds for more details.

Patch Changes

• #​1964 f43b811 - Don't publish src/ to npm.
• For efficiency, the css function now maintains a cache and will use a cached value if available when the same style text is requested.
• Fixed reflecting a property when it is set in a setter of another property that is called because its attribute changed (#​965).
• Fixed exceptions when parsing attributes from JSON (#​722).
• Fixed issue with combining static get properties on an undefined superclass with @property on a subclass ([#​890]https://github.com/Polymer/lit-element/issues/890));

v2.5.1

Compare Source

v2.5.0

Compare Source

v2.4.0

Compare Source

Changed

• Set type in package.json to "module" (#​974)

Added

• Adds a cache: boolean argument to the @query decorator as a performance optimization for properties whose queried element is not expected to change. If cache is set to true, element DOM is queried when the property is first accessed, and the value is cached so it can be immediately returned on all subsequent property accesses. (#​1013)
• Adds a selector: string argument to the @queryAssignedNodes decorator as a convenience to filter the assigned nodes by the given selector (#​1016).
• The requestUpdateInternal(name, oldValue, options) method has been added. This method is sometimes useful to call in a custom property setter to optimize performance. It is slightly more efficient than requestUpdate since it does not return the updateComplete property which can be overridden to do work.
• The protected performUpdate() method may now be called to synchronously "flush" a pending update, for example via a property setter. Note, performing a synchronous update only updates the element and not any potentially pending descendants in the element's local DOM (#​959).
• Constructible stylesheets may now be provided directly as styles, in addition to using the css tagged template function (#​853).

Fixed

• queryAssignedNodes doesn't correctly locate default slot (#​1002)

v2.3.1

Compare Source

Fixed

• Add TypeScript type declarations for older versions of TypeScript. We're currently testing back to TS 3.4. We can't commit to never breaking TypeScript builds, but we'll be supporting older versions as best we can.

v2.3.0

Compare Source

Changed

• Added a static getPropertyDescriptor method to allow easier customization of property accessors. This method should return a a PropertyDescriptor to install on the property. If no descriptor is returned, no property accessor is created. (#​911)
• The value returned by render is always rendered, even if it isn't a TemplateResult. (#​712)

Added

• Added @queryAsync(selector) decorator which returns a Promise that resolves to the result of querying for the given selector after the element's updateComplete Promise resolves (#​903).
• Added enableUpdating() to UpdatingElement to enable customizing when updating is enabled #​860.
• Added @queryAssignedNodes(slotName, flatten) decorator to enable querying assignedNodes for a given slot #​860.
• Added getStyles() to LitElement to allow hooks into style gathering for component sets #​866.
• Added @internalProperty(options) decorator to define properties internal to an element. #​881.

Fixed

• Ensure UpdatingElement allows updates when properties are set after calling super.update().
  LitElement renders when updates are triggered as a result of rendering (#​549).
• Properties annotated with the eventOptions decorator will now survive property renaming optimizations when used with tsickle and Closure JS Compiler.
• Moved style gathering from finalize to initialize to be more lazy, and create stylesheets on the first instance initializing #​866.
• Fixed behavior change for components that do not implement render() introduced in (#​712) (#​917)

v2.2.1

Compare Source

Changed

• Elements should now override the new _getUpdateComplete method instead of the updateComplete getter, for compatibility with TypeScript ES5 output, which does not support calling a superclass getter (e.g.super.updateComplete.then(...)) due to TypeScript#338.

Fixed

• Fixed compatibility with Closure JS Compiler optimizations relating to static properties (#​732).
