• useGenerate - React hook to generate a response for a given prompt with a provided model.

import { useGenerate } from 'react-ollama';

export const GenerateExample = () => {
  const { answer, sendMessage } = useGenerate('llama3.2');

  const handleClick = () => {
    sendMessage({
      prompt: 'What is the meaning of life?',
      stream: true
    });
  };

  return (
    <div>
      <button onClick={handleClick}>Generate</button>
      <p>{answer}</p>
    </div>
  );
};

• useChat - React hook to interact with Ollama in a chat-like interface.

import { useChat } from 'react-ollama';

export const ChatExample = () => {
  const { answer, sendMessage } = useChat('llama3.2');

  const handleClick = () => {
    sendMessage({
      messages: [
        {
          role: 'user',
          content: 'You are an expert philosopher. Give me an answer in 20 words or less.'
        },
        {
          role: 'user',
          content: 'Now, tell me: what is the meaning of life?'
        }
      ],
      stream: true
    });
  };

  return (
    <div>
      <button onClick={handleClick}>Chat</button>
      <p>{answer}</p>
    </div>
  );
};

• reactOllama - function to interact with the Ollama in a more flexible way. Supports Server Components and all of the Ollama API endpoints. Provides the following methods:

  • generate - Generate a response for a given prompt with a provided model.
  • chat - Generate the next message in a chat with a provided model.
  • pullModel - Downloads a model from the Ollama library.
  • pushModel - Uploads a model to the Ollama library.
  • createModel - Creates a new model from a base model.
  • deleteModel - Deletes a model and it's data.
  • copyModel - Copies a model to create a new model with a different name.
  • listModels - Lists all available local models.
  • showModel - Shows metadata of a specific model.
  • listRunningModels - Lists all currently running models.
  • generateEmbed - Generates an embed from a model.
  • abort - Aborts all streamed generations currently running.

import { isAbortable, reactOllama } from 'react-ollama';

export const ServerReactOllama = async () => {
  const { generate, listRunningModels, listModels } = reactOllama();

  const generateResponse = await generate({
    model: 'llama3.2',
    prompt: 'What is the meaning of life?',
    stream: false
  });

  const content =
    !isAbortable(generateResponse) && generateResponse ? generateResponse.response : '';

  const runningModels = await listRunningModels();
  const models = await listModels();

  return (
    <div>
      <div>{content}</div>
      {runningModels.map((m) => (
        <div key={m.model}>
          <h1>{m.name}</h1>
        </div>
      ))}
      {models.map((m) => (
        <div key={m.model}>
          <h1>{m.name}</h1>
        </div>
      ))}
    </div>
  );
};

react-ollama comes in with default Ollama client, but you are free to provide your own clients:

import { Ollama } from 'react-ollama';

export const ollamaInstance = new Ollama({
  host: 'http://localhost:8000'
});

import { ollamaInstance } from './ollamaInstance';
import { useGenerate } from 'react-ollama';

export const CustomOllamaComponent = () => {
  const { answer, sendMessage } = useGenerate('llama3.2', ollamaInstance);

  const handleClick = () => {
    sendMessage({
      prompt: 'What is the meaning of life?',
      stream: true
    });
  };

  return (
    <div>
      <button onClick={handleClick}>Generate</button>
      <p>{answer}</p>
    </div>
  );
};
