## README

# 🦜✂️ @langchain/textsplitters

This package contains various implementations of LangChain.js text splitters, most commonly used as part of retrieval-augmented generation (RAG) pipelines.

## Installation

```bash npm2yarn
npm install @langchain/textsplitters @langchain/core
```

## Development

To develop the `@langchain/textsplitters` package, you'll need to follow these instructions:

pnpm install
```

### Build the package

```bash
pnpm build
```

Or from the repo root:

```bash
pnpm build --filter @langchain/textsplitters
```

### Run tests

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`:

```bash
$ pnpm test
$ pnpm test:int
```

### Lint & Format

Run the linter & formatter to ensure your code is up to standard:
