lifecycle
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.
disconnectedCallback() {
super.disconnectedCallback();
window.removeEventListener('keydown', this._handleKeydown);
}
An element may be re-connected after being disconnected.
Returns
void

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

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

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:
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.

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.
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
