renderVersionMismatch()

renderVersionMismatch(expectedVersion, actualVersion): TemplateResult

Render a warning message when the block version is mismatched.

Parameters

• expectedVersion: number

If the schema is not found, the expected version is -1. Which means the block is not supported in the current editor.

• actualVersion: number

The version of the block's crdt data.

Returns

TemplateResult

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

Inherited from

CaptionedBlockComponent.disconnectedCallback

Defined in

packages/framework/block-std/dist/view/element/block-component.d.ts:40

rendering

createRenderRoot()

createRenderRoot(): HTMLElement | DocumentFragment

Returns

HTMLElement | DocumentFragment

Inherited from

CaptionedBlockComponent.createRenderRoot

Defined in

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

---

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

Inherited from

CaptionedBlockComponent.render

Defined in

packages/framework/block-std/dist/view/element/block-component.d.ts:42

styles

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:

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

Nocollapse

Overrides

CaptionedBlockComponent.styles

Defined in

packages/blocks/src/database-block/database-block.ts:50

---

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

CaptionedBlockComponent.finalizeStyles

Defined in

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

updates

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:

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

CaptionedBlockComponent.getUpdateComplete

Defined in

packages/framework/block-std/dist/view/element/block-component.d.ts:41

---

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

• changedProperties: PropertyValueMap<any> | Map<PropertyKey, unknown>

Map of changed properties with old values

Returns

void

Inherited from

CaptionedBlockComponent.update

Defined in

packages/framework/block-std/dist/view/element/block-component.d.ts:51
