@hashbrownai/ollama is the Node adapter for Ollama. It maps an AG-UI run from Hashbrown's React or Angular packages to the Ollama SDK and streams AG-UI events back, so you can run local models.

Getting Started

Install the Hashbrown adapter, official Ollama SDK, and AG-UI packages:

npm install @hashbrownai/ollama ollama @ag-ui/core @ag-ui/encoder

HashbrownOllama.stream.text() maps an AG-UI run to Ollama and returns canonical AG-UI events. Encode the events as SSE at your HTTP boundary:

import type { RunAgentInput } from '@ag-ui/core';
import { EventEncoder } from '@ag-ui/encoder';
import { HashbrownOllama } from '@hashbrownai/ollama';
import express from 'express';

const app = express();
app.use(express.json());

app.post('/run', async (req, res) => {
  const abortController = new AbortController();
  req.once('aborted', () => abortController.abort());
  res.once('close', () => abortController.abort());
  const stream = HashbrownOllama.stream.text({
    model: process.env.OLLAMA_MODEL ?? 'gemma3',
    input: req.body as RunAgentInput,
    signal: abortController.signal,
  });
  const encoder = new EventEncoder();

  res.header('Cache-Control', 'no-cache, no-store, must-revalidate');
  res.header('Content-Type', encoder.getContentType());
  res.header('Connection', 'keep-alive');
  res.flushHeaders();

  for await (const event of stream) {
    res.write(encoder.encodeSSE(event));
  }

  if (!res.writableEnded) {
    res.end();
  }
});

app.listen(3000);
