Last year, Google Cloud and LangChain announced integrations to give generative AI developers access to LangChain Python packages for leveraging Google Cloud's database portfolio.
The integrations have now expanded language support to include Go, Java, and JavaScript.
Developers can use vector stores, chat message history, and document loaders within the LangChain integrations.
This technology enables applications like personalized product recommendations, question answering, and customer service automation.
Java and Go are commonly used for production-grade applications, while JavaScript and TypeScript are preferred for asynchronous programming and front-end compatibility.
Google Cloud integrates secure connections, SSL certificate handling, and IAM authentication for PostgreSQL databases.
LangChain.js for JavaScript developers provides tools for connecting large language models to data sources and reasoning capabilities.
LangChain4j is available for Java developers, offering access to VertexAI Gemini models for LLM-powered applications.
LangChainGo supports Go developers with AlloyDB and Cloud SQL for PostgreSQL integration for data-aware and agentic applications.
Integrations include vector stores, memory, and document loaders, with code snippets provided for each language.
