LangChain Community Integration

Integrate and configure LangChain Community package - a collection of third-party integrations that implement LangChain Core interfaces for building AI applications in JavaScript/TypeScript.

What This Skill Does

This skill helps you install, configure, and use the `@langchain/community` package, which provides community-maintained integrations for LangChain.js. It handles proper dependency management to ensure compatibility with `@langchain/core` and other LangChain packages.

Instructions

When a user requests LangChain Community integration, follow these steps:

1. Check Project Setup

First, verify the project structure and package manager:

2. Install the Package

```bash

For pnpm (recommended)

pnpm install @langchain/community

For npm

npm install @langchain/community

For yarn

```

3. Configure Dependency Resolution

},

"pnpm": {
