@langchain/mongodb

This package contains the LangChain.js integrations for MongoDB through their SDK.

Installation

npm install @langchain/mongodb
Copy

This package, along with the main LangChain package, depends on @langchain/core. If you are using this package with other LangChain packages, you should make sure that all of the packages depend on the same instance of @langchain/core. You can do so by adding appropriate field to your project's package.json like this:

{
  "name": "your-project",
  "version": "0.0.0",
  "dependencies": {
    "@langchain/mongodb": "^0.0.0",
    "langchain": "0.0.207"
  },
  "resolutions": {
    "@langchain/core": "0.1.5"
  },
  "overrides": {
    "@langchain/core": "0.1.5"
  },
  "pnpm": {
    "overrides": {
      "@langchain/core": "0.1.5"
    }
  }
}
Copy

The field you need depends on the package manager you're using, but we recommend adding a field for the common yarn, npm, and pnpm to maximize compatibility.

Development

To develop the MongoDB package, you'll need to follow these instructions:

Install dependencies

yarn install
Copy

Build the package

yarn build
Copy

Or from the repo root:

yarn build --filter=@langchain/mongodb
Copy

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:

$ yarn test
$ yarn test:int
Copy

Lint & Format

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

yarn lint && yarn format
Copy

Adding new entrypoints

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.
