Netlify Functions returns readable stream to browser

[jen]

Hey Nick,
What I think is happening (but am not 100% sure to be honest) is that netlify dev (written in Node) simulates a function call but does not make a call to an actual AWS function, so regular capabilties of Node like reading from streams work locally… but do not work when deployed, since AWS lambdas does not support streaming responses Sorry to be the bearer of bad news. If you learn otherwise, or if I misunderstood the problem, I would love to know. This thread has more discussion on functions and streams:

Stream content to function response body

Hi, just to add some details: As you probably already know, we use AWS lambda functions under the hood. It looks like AWS lambda functions does not currently support streaming responses for Node or Golang based functions. Only Java, which is a language we do not support. That said, we do have a feature request filed but there are some technical challenges that we will need to resolve before we’ll be able to implement this. We will update here when and if we do. Thank you for your patience.
