This package contains various implementations of LangChain.js text splitters, most commonly used as part of retrieval-augmented generation (RAG) pipelines.
npm install @langchain/textsplitters
To develop the @langchain/textsplitters package, you'll need to follow these instructions:
yarn install
yarn build
Or from the repo root:
yarn build --filter=@langchain/textsplitters
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.
