This package contains the LangChain.js integrations for Ollama via the ollama TypeScript SDK.
npm install @langchain/ollama @langchain/core
TODO: add setup instructions for Ollama locally
import { ChatOllama } from "@langchain/ollama";
const model = new ChatOllama({
model: "llama3", // Default value.
});
const result = await model.invoke(["human", "Hello, how are you?"]);
To develop the @langchain/ollama package, you'll need to follow these instructions:
yarn install
yarn build
Or from the repo root:
yarn build --filter=@langchain/ollama
Test files should live within a tests/ file in the src/ folder. Unit tests should end in .test.ts and integration tests should
end in .int.test.ts:
$ yarn test
$ yarn test:int
Run the linter & formatter to ensure your code is up to standard:
yarn lint && yarn format
If you add a new file to be exported, either import & re-export from src/index.ts, or add it to the entrypoints field in the config variable located inside langchain.config.js and run yarn build to generate the new entrypoint.
