Sending multiple responses with the same response object in Express.js

rated 0 times [ 54] [ 4] / answers: 1 / hits: 47356 / 10 Years ago, fri, august 8, 2014, 12:00:00

I have a long running process which needs to send data back at multiple stages. Is there some way to send back multiple responses with express.js

res.send(200, 'hello')

res.send(200, 'world')

res.end()

but when I run curl -X POST localhost:3001/helloworld all I get is hello

How can I send multiple responses or is this not possible to do with express?

Use res.write().

res.send() already makes a call to res.end(), meaning you can't write to res anymore after a call to res.send (meaning also your res.end() call was useless).

EDIT: It is a Node.js internal function. See the documentation here
