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:

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 ​

SignalWatcher(WithDisposable(ShadowlessElement)).getUpdateComplete

abstract BlockService ​

Deprecated ​

BlockService is deprecated. You should reconsider where to put your feature.

BlockService is a legacy extension that is used to provide services to the block. In the previous version of BlockSuite, block service provides a way to extend the block. However, in the new version, we recommend using the new extension system.

Clipboard ​

A life cycle watcher is an extension that watches the life cycle of the editor. It is used to perform actions when the editor is created, mounted, rendered, or unmounted.

When creating a life cycle watcher, you must define a key that is unique to the watcher. The key is used to identify the watcher in the dependency injection container.

ts
class MyLifeCycleWatcher extends LifeCycleWatcher {
 static override readonly key = 'my-life-cycle-watcher';

In the life cycle watcher, the methods will be called in the following order:

  1. created: Called when the std is created.
  2. rendered: Called when std.render is called.
  3. mounted: Called when the editor host is mounted.
  4. unmounted: Called when the editor host is unmounted.

CommandManager ​

Command manager to manage all commands

Commands are functions that take a context and a next function as arguments

ts
const myCommand: Command<input, output> = (ctx, next) => {
 const count = ctx.count || 0;

 const success = someOperation();
 if (success) {
   return next({ count: count + 1 });
 }
 // if the command is not successful, you can return without calling next
 return;

Command input and output data can be defined in the Command type

ts
// input: ctx.firstName, ctx.lastName
// output: ctx.fullName
const myCommand: Command<{ firstName: string; lastName: string }, { fullName: string }> = (ctx, next) => {
  const { firstName, lastName } = ctx;
  const fullName = `${firstName} ${lastName}`;
  return next({ fullName });
}

Commands can be run in two ways:

  1. Using exec method exec is used to run a single command
ts
const [result, data] = commandManager.exec(myCommand, payload);
  1. Using chain method chain is used to run a series of commands
ts
const chain = commandManager.chain();
const [result, data] = chain
  .pipe(myCommand1)
  .pipe(myCommand2, payload)
  .run();

Command chains will stop running if a command is not successful

ts
const chain = commandManager.chain();
const [result, data] = chain
  .chain(myCommand1) <-- if this fail
  .chain(myCommand2, payload) <- this won't run
  .run();

result <- result will be `false`

You can use try to run a series of commands and if one of them is successful, it will continue to the next command

ts
const chain = commandManager.chain();
const [result, data] = chain
  .try(chain => [
    chain.pipe(myCommand1), <- if this fail
    chain.pipe(myCommand2, payload), <- this will run, if this success
    chain.pipe(myCommand3), <- this won't run
  ])
  .run();

The tryAll method is similar to try, but it will run all commands even if one of them is successful

ts
const chain = commandManager.chain();
const [result, data] = chain
  .try(chain => [
    chain.pipe(myCommand1), <- if this success
    chain.pipe(myCommand2), <- this will also run
    chain.pipe(myCommand3), <- so will this
  ])
  .run();

abstract LifeCycleWatcher ​

A life cycle watcher is an extension that watches the life cycle of the editor. It is used to perform actions when the editor is created, mounted, rendered, or unmounted.

When creating a life cycle watcher, you must define a key that is unique to the watcher. The key is used to identify the watcher in the dependency injection container.

ts
class MyLifeCycleWatcher extends LifeCycleWatcher {
 static override readonly key = 'my-life-cycle-watcher';

In the life cycle watcher, the methods will be called in the following order:

  1. created: Called when the std is created.
  2. rendered: Called when std.render is called.
  3. mounted: Called when the editor host is mounted.
  4. unmounted: Called when the editor host is unmounted.

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 ​

LitElement.connectedCallback

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.

ts
disconnectedCallback() {
  super.disconnectedCallback();
  window.removeEventListener('keydown', this._handleKeydown);
}

An element may be re-connected after being disconnected.

Returns ​

void

createRenderRoot() ​

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.

Type Declaration ​

setDragData? ​

optional setDragData?: (args) => PayloadEntity

Set drag data for the draggable element.

Parameters ​

ElementGetFeedbackArgs

Returns ​

PayloadEntity

See ​

ElementGetFeedbackArgs for callback arguments

setDragPreview? ​

optional setDragPreview?: false | ((options) => void | (() => void))

Set custom drag preview for the draggable element.

setDragPreview is a function that will be called with a container element and other drag data as parameter when the drag preview is generating. Append the custom element to the container which will be used to generate the preview. Once the drag preview is generated, the container element and its children will be removed automatically.

If you want to completely disable the drag preview, just set setDragPreview to false.

Example ​
ts
dnd.draggable({
 // ...
 setDragPreview: ({ container }) => {
   const preview = document.createElement('div');
   preview.style.width = '100px';
   preview.style.height = '100px';
   preview.style.backgroundColor = 'red';
   preview.innerText = 'Custom Drag Preview';
   container.appendChild(preview);

   return () => {
     // do some cleanup
   }
 }
})
Param ​
