Azure Functions support for HTTP streams in Node.js is now generally available. With this feature, you can stream HTTP requests to, and responses from, your Functions Apps.
With HTTP Streams, scenarios like processing large data, streaming OpenAI responses, delivering dynamic content etc. are possible. Users 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.
