@aparte/plugin-streaming-markdown

Incremental (token-by-token) Markdown rendering for aparté via streaming-markdown. Parses only the new text and appends DOM nodes per streamed chunk — no per-token re-parse or innerHTML rebuild.

npm install @aparte/plugin-streaming-markdown @aparte/core streaming-markdown

import { setupStreamingMarkdownProvider } from '@aparte/plugin-streaming-markdown';

setupStreamingMarkdownProvider();

@aparte/core and streaming-markdown are peer dependencies.

This plugin is enough on its own: a reply renders the same whether it streams or arrives complete — a conversation restored after a reload, a non-streaming provider's answer — because with no one-shot provider registered, core runs the whole string through this parser too. A one-shot provider (e.g. @aparte/plugin-marked) is optional — register one and finished and restored messages are rendered through it, at that renderer's full fidelity.

Security: the streaming path writes DOM directly, bypassing the one-shot sanitizer, so it enforces the URL policy live — a streamed [x](javascript:…) never produces a clickable javascript: link — and a finished message is passed through core's sanitizer either way.

ESM-only. Part of the aparté monorepo.
