# LangChain JavaScript integrations

> Integrate with providers using LangChain JavaScript/TypeScript.

LangChain integrates with a wide variety of chat & embedding models, tools & toolkits, document loaders, vector stores, and more.

A **provider** is a third-party service or platform that LangChain integrates with to access AI capabilities like chat models, embeddings, and vector stores. These providers have standalone `langchain-provider` packages for improved versioning, dependency management, and testing.
