Plugins

@aparte/core is presentational and zero-dependency: it renders raw text, exposes seams, and asks nothing of you. Plugins fill those seams — each is an opt-in @aparte/plugin-* package that you install and wire in one call, so core stays small and you pay only for what you use.

You want…	Package	Seam it fills
Render finished Markdown messages	marked	setMarkdownProvider
Stream Markdown token-by-token	streaming-markdown	setStreamingMarkdownProvider
Highlight code blocks	shiki	setHighlightProvider
Let the user pick a provider + model	model-selector	<aparte-model-selector> element
Let the AI ask the user a question	ask-question	registerTool + elicitation

Every plugin lists @aparte/core as a peer dependency and, where it wraps a third-party library (marked, streaming-markdown, shiki), that library too — so you control its version and it is never bundled into core.

The shape of a plugin

Most plugins register something on the config once, at startup:

import { setupMarkedProvider } from '@aparte/plugin-marked';
import { setupShikiProvider } from '@aparte/plugin-shiki';

setupMarkedProvider();          // finished messages → HTML
await setupShikiProvider();     // code blocks → highlighted HTML

The two Markdown plugins are complementary: streaming-markdown renders each token as it arrives, and marked re-renders the finished message. Register both for the best of both.

Localization

Translating the built-in UI strings is its own seam — see the Localization guide and the @aparte/locale-fr package.
