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.
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
SignalWatcher(WithDisposable(LitElement)).connectedCallback
Defined in
packages/framework/block-std/src/view/element/widget-component.ts:75
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
Overrides
SignalWatcher(WithDisposable(LitElement)).disconnectedCallback

rendering
render()
render():
unknown
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
unknown
Overrides
SignalWatcher(WithDisposable(LitElement)).render
