Question

node.js doc says

response.end([data], [encoding])

This method signals to the server that all of the response headers and body have been sent; that server should consider this message complete. The method, response.end(), MUST be called on each response.

but in the many examples given using using createReadStream, eg,

 fs.createReadStream(filename,{...}).pipe(response)

I never see response.end() called.

it resonse.end() needed with createReadStream()? and, if so, where does it appear in the program flow – you don’t want it called until the pipe is finished, right?

Answer 1

You do response.end() after reading is finished (end event) or you encounter an error (error event).
