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

Overrides ​

WithDisposable(ShadowlessElement).connectedCallback

Defined in ​

packages/presets/src/editors/page-editor.ts:56

rendering ​

createRenderRoot() ​

createRenderRoot(): HTMLElement | DocumentFragment

Returns ​

HTMLElement | DocumentFragment

Inherited from ​

WithDisposable(ShadowlessElement).createRenderRoot

Defined in ​

packages/framework/block-std/dist/view/element/shadowless-element.d.ts:6

render() ​

render(): typeof nothing | 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 ​

typeof nothing | TemplateResult<1>

Overrides ​

WithDisposable(ShadowlessElement).render

Defined in ​

packages/presets/src/editors/page-editor.ts:73

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 ​

• styles?: CSSResultGroup

Returns ​

CSSResultOrNative[]

Nocollapse ​

Inherited from ​

WithDisposable(ShadowlessElement).finalizeStyles

Defined in ​

packages/framework/block-std/dist/view/element/shadowless-element.d.ts:5

updates ​

getUpdateComplete() ​

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.

Overrides ​

WithDisposable(ShadowlessElement).getUpdateComplete

Defined in ​

packages/presets/src/editors/page-editor.ts:67

willUpdate() ​

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 ​

• changedProperties: Map<string | number | symbol, unknown>

Returns ​

void

Overrides ​

WithDisposable(ShadowlessElement).willUpdate

Defined in ​

packages/presets/src/editors/page-editor.ts:88
