I was playing around with Ollama and getting streaming responses to work, made a custom interface using tailwind and alpinejs, served from node-red using a websocket, libraries are coming from cdn's but could be included locally too, but example flow became too large.
Simple flow, setup the ollama server address and model (make sure that ollama is accessible outside localhost), inject it once (will set a flow variable).
Open a browser window and point it to /ollama_chat and hopefully you can chat with your ollama llm.
Type anything and click send or use ctrl+enter to submit it.
Currently the interaction is based on llama2, will need some modifications when interacting with other models.
The ollama chat function will install the ollama npm package as dependency.
Using node-red for this does not directly make sense, but that's not the point :')
It types/streams responses
