IBM is acquiring DataStax to accelerate production of artificial intelligence (AI) and NoSQL data at scale. Langflow, a tool for building flows and AI agents, can be integrated into applications through its API, which allows developers to experiment with generative AI. The @datastax/langflow-client npm module makes it easy to use the Langflow API in Node.js, and streaming GenAI outputs can improve user experience. To stream results from a Langflow flow in Node.js, developers need a flow set up for streaming responses, which requires a model with streaming capabilities and a chat output connected to it. The Langflow client can be used with both self-hosted and DataStax-hosted versions of the platform, and provides a way to log out just the text from a flow response or make API requests from an Express server.
