Functions chunky response

[nmalevich]

Description

I write response by chunks. On my local server it works, but Firebase Function return response only after "res.end()"

exports.cloudFunctionEntryPoint = async (req, res) => {
    setTimeout(()=>{
        res.write("1\n");
    }, 1000)
    setTimeout(()=>{
        res.write("2\n");
    }, 2000)
    setTimeout(()=>{
        res.write("3\n");
    }, 3000)
    setTimeout(()=>{
        res.write("4\n");
    }, 4000)
    setTimeout(()=>{
        res.write("5\n");
        res.end();
    }, 5000)
}

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @nmalevich, could you provide a code snippet of your Firebase Functions and iOS code invoking the function so I could reproduce it on my end? Thanks.

Thank you for your reply. My general question about having possibility to implement streaming data(sending response by chunks)
