EdgelessLocker ​

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.

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:

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

updates ​

firstUpdated() ​

firstUpdated(): void

Invoked when the element is first updated. Implement to perform one time work on the element after update.

ts
firstUpdated() {
  this.renderRoot.getElementById('my-text-area').focus();
}

Setting properties inside this method will trigger the element to update again after this update cycle completes.

EdgelessRootService ​

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.
