llm-stream-reformat

Reformat a live LLM token stream while it's still arriving — separate a reasoning model's thinking from its answer, collapse repetition loops, and normalize whitespace. Parses Google Vertex (gemini-3.7-flash), OpenRouter, and meta-llm SSE.

Rust + WebAssembly, built on the real ruvnet/midstream temporal-compare primitive. Node + browser.

npm install llm-stream-reformat

const { Reformatter } = require('llm-stream-reformat');
const rf = new Reformatter();
for (const line of sseLines) {
  for (const ev of rf.pushSse('google', line)) {
    if (ev.channel === 'thinking') showReasoning(ev.text);
    else appendAnswer(ev.text);
  }
}
rf.finish().forEach(ev => appendAnswer(ev.text));

Browser: import { init, Reformatter } from 'llm-stream-reformat/web'; await init();
