addInitializer() ​

static addInitializer(initializer): void

Adds an initializer function to the class that is called during instance construction.

This is useful for code that runs against a ReactiveElement subclass, such as a decorator, that needs to do work for each instance, such as setting up a ReactiveController.

ts
const myDecorator = (target: typeof ReactiveElement, key: string) => {
  target.addInitializer((instance: ReactiveElement) => {
    // This is run during construction of the element
    new MyController(instance);
  });
}

Decorating a field will then cause each instance to run an initializer that adds a controller:

ts
class MyElement extends LitElement {
  @myDecorator foo;
}

Initializers are stored per-constructor. Adding an initializer to a subclass does not add it to a superclass. Since initializers are run in constructors, initializers will run in order of the class hierarchy, starting with superclasses and progressing to the instance's class.

Parameters ​

ParameterType
initializerInitializer

Returns ​

void

finalize() ​

protected static finalize(): void

Finishes setting up the class so that it's ready to be registered as a custom element and instantiated.

This method is called by the ReactiveElement.observedAttributes getter. If you override the observedAttributes getter, you must either call super.observedAttributes to trigger finalization, or call finalize() yourself.

Returns ​

attributeChangedCallback() ​

attributeChangedCallback(name, _old, value): void

Synchronizes property values when attributes change.

Specifically, when an attribute is set, the corresponding property is set. You should rarely need to implement this callback. If this method is overridden, super.attributeChangedCallback(name, _old, value) must be called.

See using the lifecycle callbacks on MDN for more information about the attributeChangedCallback.

Parameters ​

ParameterType
namestring
_oldstring | null
valuestring | null

Returns ​

void

Inherited from ​

LitElement.attributeChangedCallback

controllers ​

addController() ​

addController(controller): void

Registers a ReactiveController to participate in the element's reactive update cycle. The element automatically calls into any registered controllers during its lifecycle callbacks.

If the element is connected when addController() is called, the controller's hostConnected() callback will be immediately called.

Parameters ​

ParameterType
controllerReactiveController

Returns ​

void

Inherited from ​

LitElement.addController


removeController() ​

removeController(controller): void

Removes a ReactiveController from the element.

Parameters ​

ParameterType

disableWarning()? ​

static optional disableWarning: (warningKind) => void

Disable the given warning category for this class.

This method only exists in development builds, so it should be accessed with a guard like:

ts
// Disable for all ReactiveElement subclasses
ReactiveElement.disableWarning?.('migration');

// Disable for only MyElement and subclasses
MyElement.disableWarning?.('migration');

Parameters ​

ParameterType
warningKindWarningKind

lifecycle ​

connectedCallback() ​

connectedCallback(): void

Invoked when the component is added to the document's DOM.

In connectedCallback() you should setup tasks that should only occur when the element is connected to the document. The most common of these is adding event listeners to nodes external to the element, like a keydown event handler added to the window.

ts
connectedCallback() {
  super.connectedCallback();
  addEventListener('keydown', this._handleKeydown);
}

Typically, anything done in connectedCallback() should be undone when the element is disconnected, in disconnectedCallback().

Returns ​

void

Inherited from ​

LitElement.connectedCallback


disconnectedCallback() ​

disconnectedCallback(): void

Invoked when the component is removed from the document's DOM.

This callback is the main signal to the element that it may no longer be used. disconnectedCallback() should ensure that nothing is holding a reference to the element (such as event listeners added to nodes external to the element), so that it is free to be garbage collected.

ts
disconnectedCallback() {
  super.disconnectedCallback();
  window.removeEventListener('keydown', this._handleKeydown);
}

An element may be re-connected after being disconnected.

Returns ​

void

Inherited from ​

LitElement.disconnectedCallback

properties ​

elementProperties ​

static elementProperties: PropertyDeclarationMap

Memoized list of all element properties, including any superclass properties. Created lazily on user subclasses when finalizing the class.

Nocollapse ​

Inherited from ​

LitElement.elementProperties


properties ​

static properties: PropertyDeclarations

User-supplied object that maps property names to PropertyDeclaration objects containing options for configuring reactive properties. When a reactive property is set the element will update and render.

By default properties are public fields, and as such, they should be considered as primarily settable by element users, either via attribute or the property itself.

Generally, properties that are changed by the element should be private or protected fields and should use the state: true option. Properties marked as state do not reflect from the corresponding attribute

However, sometimes element code does need to set a public property. This should typically only be done in response to user interaction, and an event should be fired informing the user; for example, a checkbox sets its checked property when clicked and fires a changed event. Mutating public properties should typically not be done for non-primitive (object or array) properties. In other cases when an element needs to manage state, a private property set with the state: true option should be used. When needed, state properties can be initialized via public properties to facilitate complex interactions.

LitElement.properties


createProperty() ​

static createProperty(name, options?): void

Creates a property accessor on the element prototype if one does not exist and stores a PropertyDeclaration for the property with the given options. The property setter calls the property's hasChanged property option or uses a strict identity check to determine whether or not to request an update.

This method may be overridden to customize properties; however, when doing so, it's important to call super.createProperty to ensure the property is setup correctly. This method calls getPropertyDescriptor internally to get a descriptor to install. To customize what properties do when they are get or set, override getPropertyDescriptor. To customize the options for a property, implement createProperty like this:

ts
static createProperty(name, options) {
  options = Object.assign(options, {myOption: true});
  super.createProperty(name, options);
}

Parameters ​

ParameterType
namePropertyKey
options?PropertyDeclaration<unknown, unknown>

Returns ​

void

Nocollapse ​

Inherited from ​

LitElement.createProperty


getPropertyDescriptor() ​

protected static getPropertyDescriptor(name, key, options): PropertyDescriptor | undefined

Returns a property descriptor to be defined on the given named property. If no descriptor is returned, the property will not become an accessor. For example,

ts
class MyElement extends LitElement {
  static getPropertyDescriptor(name, key, options) {
    const defaultDescriptor =
        super.getPropertyDescriptor(name, key, options);
    const setter = defaultDescriptor.set;
    return {
      get: defaultDescriptor.get,
      set(value) {
        setter.call(this, value);
        // custom action.
      },
      configurable: true,
      enumerable: true
    }
  }
}

Returns ​

PropertyDescriptor | undefined

Nocollapse ​

Inherited from ​

LitElement.getPropertyDescriptor


getPropertyOptions() ​

static getPropertyOptions(name): PropertyDeclaration<unknown, unknown>

Returns the property options associated with the given property. These options are defined with a PropertyDeclaration via the properties object or the @property decorator and are registered in createProperty(...).

Note, this method should be considered "final" and not overridden. To customize the options for a given property, override createProperty.

Parameters ​

renderRoot ​

readonly renderRoot: HTMLElement | DocumentFragment

Node or ShadowRoot into which element DOM should be rendered. Defaults to an open shadowRoot.

Inherited from ​

LitElement.renderRoot


shadowRootOptions ​

static shadowRootOptions: ShadowRootInit

Options used when calling attachShadow. Set this property to customize the options for the shadowRoot; for example, to create a closed shadowRoot: {mode: 'closed'}.

Note, these options are used in createRenderRoot. If this method is customized, options should be respected if possible.

createRenderRoot() ​

protected createRenderRoot(): SdkMapElement

Returns ​

SdkMapElement

Overrides ​

LitElement.createRenderRoot


render() ​

render(): TemplateResult<1>

Invoked on each update to perform rendering tasks. This method may return any value renderable by lit-html's ChildPart - typically a TemplateResult. Setting properties inside this method will not trigger the element to update.

Returns ​

TemplateResult<1>

Overrides ​

LitElement.render

styles ​

elementStyles ​

static elementStyles: CSSResultOrNative[]

Memoized list of all element styles. Created lazily on user subclasses when finalizing the class.

Nocollapse ​

Inherited from ​

LitElement.elementStyles


styles ​

static styles: CSSResult

Array of styles to apply to the element. The styles should be defined using the css tag function, via constructible stylesheets, or imported from native CSS module scripts.

Note on Content Security Policy:

Element styles are implemented with <style> tags when the browser doesn't support adopted StyleSheets. To use such <style> tags with the style-src CSP directive, the style-src value must either include 'unsafe-inline' or nonce-<base64-value> with <base64-value> replaced be a server-generated nonce.

To provide a nonce to use on generated <style> elements, set window.litNonce to a server-generated nonce in your page's HTML, before loading application code:

html
<script>
  // Generated and unique per request:
  window.litNonce = 'a1b2c3d4';
</script>

Nocollapse ​

Overrides ​

LitElement.styles


finalizeStyles() ​

protected static finalizeStyles(styles?): CSSResultOrNative[]

Takes the styles the user supplied via the static styles property and returns the array of styles to apply to the element. Override this method to integrate into a style management system.

Styles are deduplicated preserving the last instance in the list. This is a performance optimization to avoid duplicated styles that can occur especially when composing via subclassing. The last item is kept to try to preserve the cascade order with the assumption that it's most important that last added styles override previous styles.

Parameters ​

ParameterType
styles?CSSResultGroup

Returns ​

CSSResultOrNative[]

updates ​

hasUpdated ​

hasUpdated: boolean

Is set to true after the first update. The element code cannot assume that renderRoot exists before the element hasUpdated.

Inherited from ​

LitElement.hasUpdated


isUpdatePending ​

isUpdatePending: boolean

True if there is a pending update as a result of calling requestUpdate(). Should only be read.

Inherited from ​

LitElement.isUpdatePending


updateComplete ​

Get Signature ​

get updateComplete(): Promise<boolean>

Returns a Promise that resolves when the element has completed updating. The Promise value is a boolean that is true if the element completed the update without triggering another update. The Promise result is false if a property was set inside updated(). If the Promise is rejected, an exception was thrown during the update.

To await additional asynchronous work, override the getUpdateComplete method. For example, it is sometimes useful to await a rendered element before fulfilling this Promise. To do this, first await super.getUpdateComplete(), then any subsequent state.

Returns ​

Promise<boolean>

A promise of a boolean that resolves to true if the update completed without triggering another update.

Inherited from ​

LitElement.updateComplete


enableUpdating() ​

protected enableUpdating(_requestedUpdate): void

Note, this method should be considered final and not overridden. It is overridden on the element instance with a function that triggers the first update.

Parameters ​

ParameterType
_requestedUpdateboolean

Returns ​

void

Inherited from ​

LitElement.enableUpdating


firstUpdated() ​

firstUpdated(): Promise<void>

Invoked when the element is first updated. Implement to perform one time work on the element after update.

ts
firstUpdated() {
  this.renderRoot.getElementById('my-text-area').focus();
}

Setting properties inside this method will trigger the element to update again after this update cycle completes.

Returns ​

Promise<void>

Overrides ​

LitElement.firstUpdated


getUpdateComplete() ​

protected getUpdateComplete(): Promise<boolean>

Override point for the updateComplete promise.

It is not safe to override the updateComplete getter directly due to a limitation in TypeScript which means it is not possible to call a superclass getter (e.g. super.updateComplete.then(...)) when the target language is ES5 (https://github.com/microsoft/TypeScript/issues/338). This method should be overridden instead. For example:

ts
class MyElement extends LitElement {
  override async getUpdateComplete() {
    const result = await super.getUpdateComplete();
    await this._myChild.updateComplete;
    return result;
  }
}

Returns ​

Promise<boolean>

A promise of a boolean that resolves to true if the update completed without triggering another update.

Inherited from ​

LitElement.getUpdateComplete


performUpdate() ​

protected performUpdate(): void

Performs an element update. Note, if an exception is thrown during the update, firstUpdated and updated will not be called.

Call performUpdate() to immediately process a pending update. This should generally not be needed, but it can be done in rare cases when you need to update synchronously.

Returns ​

void

Inherited from ​

LitElement.performUpdate


requestUpdate() ​

requestUpdate(name?, oldValue?, options?): void

Requests an update which is processed asynchronously. This should be called when an element should update based on some state not triggered by setting a reactive property. In this case, pass no arguments. It should also be called when manually implementing a property setter. In this case, pass the property name and oldValue to ensure that any configured property options are honored.

Parameters ​

ParameterTypeDescription
name?PropertyKeyname of requesting property
oldValue?unknownold value of requesting property
options?PropertyDeclaration<unknown, unknown>property options to use instead of the previously configured options

Returns ​

void

Inherited from ​

LitElement.requestUpdate


scheduleUpdate() ​

protected scheduleUpdate(): void | Promise<unknown>

Schedules an element update. You can override this method to change the timing of updates by returning a Promise. The update will await the returned Promise, and you should resolve the Promise to allow the update to proceed. If this method is overridden, super.scheduleUpdate() must be called.

For instance, to schedule updates to occur just before the next frame:

ts
override protected async scheduleUpdate(): Promise<unknown> {
  await new Promise((resolve) => requestAnimationFrame(() => resolve()));
  super.scheduleUpdate();
}

Returns ​

void | Promise<unknown>

Inherited from ​

LitElement.scheduleUpdate


shouldUpdate() ​

protected shouldUpdate(_changedProperties): boolean

Controls whether or not update() should be called when the element requests an update. By default, this method always returns true, but this can be customized to control when to update.

Parameters ​

ParameterTypeDescription
_changedPropertiesPropertyValueMap<any> | Map<PropertyKey, unknown>Map of changed properties with old values

Returns ​

boolean

Inherited from ​

LitElement.shouldUpdate


update() ​

protected update(changedProperties): void

Updates the element. This method reflects property values to attributes and calls render to render DOM via lit-html. Setting properties inside this method will not trigger another update.

Parameters ​

ParameterTypeDescription
changedPropertiesPropertyValueMap<any> | Map<PropertyKey, unknown>Map of changed properties with old values

Returns ​

void

Inherited from ​

LitElement.update


updated() ​

updated(changedProperties): Promise<void>

Invoked whenever the element is updated. Implement to perform post-updating tasks via DOM APIs, for example, focusing an element.

Setting properties inside this method will trigger the element to update again after this update cycle completes.

Parameters ​

ParameterType
changedPropertiesPropertyValueMap<SdkMapElement>

Returns ​

Promise<void>

Overrides ​

LitElement.updated


willUpdate() ​

protected willUpdate(_changedProperties): void

Invoked before update() to compute values needed during the update.

Implement willUpdate to compute property values that depend on other properties and are used in the rest of the update process.

ts
willUpdate(changedProperties) {
  // only need to check changed properties for an expensive computation.
  if (changedProperties.has('firstName') || changedProperties.has('lastName')) {
    this.sha = computeSHA(`${this.firstName} ${this.lastName}`);
  }
}

render() {
  return html`SHA: ${this.sha}`;
}

Parameters ​
