EmbedExtensionsComponent

A component that registers and unregisters embed extensions.

This component is useful for plugins that want to register custom embed types for specific file extensions. It ensures that the extensions are registered when the component is loaded and unregistered when the component is unloaded.

Import:

import { EmbedExtensionsComponent } from 'obsidian-dev-utils/obsidian/components/embed-extensions-component';

Signature:

export class EmbedExtensionsComponent extends ComponentEx

Extends: ComponentEx

Constructor

new EmbedExtensionsComponent(app: App)

Creates a new instance of the EmbedExtensionsComponent class.

Methods

Method	Returns	Description
[Symbol.dispose]()	void	Disposes of the component. (Inherited from ComponentEx)
addChild(component)	TComponent	Adds a child component. Mirrors the native Component.addChild contract: if this component is already loaded, the child is loaded immediately, so child._loaded is set before this method returns even when this component has async load logic. The child's async tail (if any) is sequenced into the load promise so a later loadWithPromises call awaits it. (Inherited from ComponentEx)
ensureLoaded()	void	Ensures the component is loaded, throwing if it is not. Use this to guard public methods that register teardown-bearing resources (via Component.register, Component.registerEvent, Component.registerDomEvent, etc.). Registering before load is unsafe: Component.unload is a no-op while the component is not loaded, so any teardown registered beforehand would never run if the component is unloaded without first being loaded. (Inherited from ComponentEx)
load()	void	Loads the component. (Inherited from ComponentEx)
loadWithPromises()	null | Promise<void>	Loads the component with promises. Unlike load, this method never rejects with an individual error: every failure raised by onloadAsync or a child's load is collected, and once everything settles the returned Promise rejects with a single AggregateError holding all of them. Non-Error throwables are normalized via ErrorWrapper.create. (Inherited from ComponentEx)
onloadAsync()	Promise<void>	Asynchronously loads the component. Override to add async load logic, which is executed after Component.onload. (Inherited from ComponentEx)
registerDisposable(disposable)	TDisposable	Registers a Disposable so it is disposed when this component unloads, and returns it unchanged. The recurring "tie a disposable to the component's lifecycle, then keep using it" idiom: the disposable is disposed on Component.unload (or earlier, if the caller disposes it directly — dispose is expected to be idempotent). Guard with ensureLoaded at the call site when registering before load would be unsafe. (Inherited from ComponentEx)
registerExtensions(extensions, embedCreator)	void	Registers the specified file extensions with the given embed type in the Obsidian app. The extensions will be automatically unregistered when the component is unloaded.
removeChild(component)	TComponent	Removes a child component. (Inherited from ComponentEx)
