Azure Functions support for HTTP streams in Node.js is now in preview. With this feature, you can now stream HTTP requests to, and responses from, your Functions Apps.
This release makes scenarios like processing large data, streaming OpenAI responses, delivering dynamic content etc. possible. You can leverage this feature for use cases where real time exchange and interaction between client and server over HTTP connections is needed. We recommend using streams to get the best performance and reliability for your apps.
HTTP Streams in Node.js is supported only in the Azure Functions Node.js v4 programming model. Check out the blog post to learn how to enable this feature in your Node.js Functions App: https://aka.ms/AzFuncNodeHttpStreams
