Shared TypeScript type contracts for elizaOS native plugin bridges.

What this package does

This is a type-only workspace package. It provides canonical TypeScript interfaces and type aliases used by elizaOS plugins that bridge between web, Capacitor (mobile), and Electrobun (desktop) runtimes. It contains no runtime code and registers no elizaOS plugin actions, providers, or services.

Exported types

Native bridge contracts

• EventCallback<T> — generic event callback used across Capacitor and Electrobun plugin bridges.
• ListenerEntry<TEventName, TEventData> — listener entry shape consumed by Electrobun plugin bridges.

Web Speech API shims

TypeScript's lib.dom.d.ts does not expose SpeechRecognition in all compiler targets. These minimal interfaces cover the surface used by web implementations of speech-enabled plugins (e.g. Swabble, TalkMode):

• SpeechRecognitionInstance — minimal interface for a Web Speech API SpeechRecognition instance.
• SpeechRecognitionResultEvent — result event shape.
• SpeechRecognitionResultList — indexed result list with isFinal and transcript.
• SpeechRecognitionCtor — constructor type for SpeechRecognitionInstance.
• SpeechRecognitionWindow — window augmentation type declaring optional SpeechRecognition and webkitSpeechRecognition properties.

Usage

This package is consumed as a workspace:* dependency by other plugins in the elizaOS monorepo:

import type { EventCallback, SpeechRecognitionInstance } from "@elizaos/native-plugin-shared-types";

Requirements

No environment variables. No configuration. No build step — the package exports TypeScript source directly.

Notes

• "private": true — not published to npm; used only within the elizaOS monorepo workspace.
• All types are in a single file: src/index.ts.
