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 @langchain/core
To develop the @langchain/textsplitters
package, you'll need to follow these instructions:
pnpm install
pnpm build
Or from the repo root:
pnpm 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
:
$ pnpm test
$ pnpm test:int
Run the linter & formatter to ensure your code is up to standard:
pnpm lint && pnpm format
If you add a new file to be exported, either import & re-export from src/index.ts
, or add it to the exports
field in the package.json
file and run pnpm build
to generate the new entrypoint.
