The ExtensionManager acts as the compiler for your editor, merging all extensions into a single cohesive rule set in two phases (Schema building, then full resolution).

Constructor

new ExtensionManager(extensions: Extension[])

Accepts the array of extensions provided to the Editor. Resolves them sequentially, meaning later extensions override earlier conflicts.

Properties

`schema`

readonly schema: Schema

The final merged ProseMirror schema built from all extensions' addNodes() and addMarks().

Methods

State & Setup

`createState(doc?: ProseMirrorNode)`

createState(doc?: ProseMirrorNode): EditorState

Creates a new EditorState utilizing the built schema and plugins. Optionally seeds it with an initial document.

`buildInitialDoc()`

buildInitialDoc(): ProseMirrorNode | undefined

Extracts the first non-null initial document contributed by any extension (e.g., pulling a Y.js synced doc).

`buildPageConfig()`

buildPageConfig(): PageConfig | undefined

Retrieves the PageConfig from either a standalone "pagination" extension or the StarterKit options.

Plugin & Keymap Builders

`buildPlugins()`

buildPlugins(): Plugin[]

Returns a flat array of all ProseMirror Plugin instances, automatically appending the merged keymap and input rules.

`buildKeymap()`

buildKeymap(): Record<string, Command>

Returns the merged keymap used to dispatch KeyboardEvents natively without a ProseMirror EditorView.

`buildInputRules()`

buildInputRules(): InputRule[]

Returns all input rules (like markdown shortcuts) collected across extensions.

`buildInputHandlers()`

buildInputHandlers(): Record<string, InputHandler>

Returns raw native KeyboardEvent interceptors.

`buildCommands()`

buildCommands(): Record<string, (...args: unknown[]) => Command>

Creates the bound dictionary of commands exposed on editor.commands.

Layout & Rendering Builders

`buildBlockRegistry() / buildInlineRegistry()`

buildBlockRegistry(): BlockRegistry
buildInlineRegistry(): InlineRegistry

Extracts layoutHandlers and inlineHandlers from extensions into O(1) registries for the rendering engine.

`buildBlockStyles() / buildFontModifiers()`

buildBlockStyles(): FontConfig
buildFontModifiers(): Map<string, FontModifier>

Aggregates CSS fonts, line heights, and styling rules declared on blocks and marks.

`buildMarkDecorators()`

buildMarkDecorators(): Map<string, MarkDecorator>

Collects custom Canvas rendering loops (decorations) applied under/over inline marks.

`buildToolbarItems()`

buildToolbarItems(): ToolbarItemSpec[]

Returns the flat array of UI specifications utilized to build React floating menus.

Markdown & Paste Builders

`buildMarkdownRules() / buildMarkdownParserTokens()`

buildMarkdownRules(): MarkdownBlockRule[]
buildMarkdownParserTokens(): Record<string, MarkdownParserTokenSpec>

Passes all custom syntax mapping down to the PasteTransformer for accurate CommonMark ingestion.

`buildMarkdownSerializerRules()`

buildMarkdownSerializerRules(): Required<MarkdownSerializerRules>

Mapping rules to export ProseMirror nodes back into Markdown string literals.

Lifecycle Builders

`buildEditorReadyCallbacks()`

buildEditorReadyCallbacks(): Array<(editor: IEditor) => (() => void) | void>

Extracts cleanup mechanisms and onEditorReady bootstrap scripts that trigger immediately after Editor initialization.
