Learn more about how to use this package in the LangChain documentation:
Installation
npm install @langchain/azure-cosmosdb @langchain/core
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 fields to your project's package.json
like this:
{
"name": "your-project",
"version": "0.0.0",
"dependencies": {
"@langchain/core": "^0.3.0",
"@langchain/azure-cosmosdb": "^0.2.5"
},
"resolutions": {
"@langchain/core": "0.3.0"
},
"overrides": {
"@langchain/core": "0.3.0"
},
"pnpm": {
"overrides": {
"@langchain/core": "0.3.0"
}
}
}
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.
