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

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

BlockComponent.render

Defined in

packages/framework/block-std/src/view/element/block-component.ts:258

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

BlockComponent.finalizeStyles

Defined in

packages/framework/block-std/src/view/element/shadowless-element.ts:21

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

BlockComponent.getUpdateComplete

Defined in

packages/framework/block-std/src/view/element/block-component.ts:252

---

scheduleUpdate()

scheduleUpdate(): Promise<void>

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:

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

Returns

Promise<void>

Overrides

BlockComponent.scheduleUpdate
