Continue execution after sending response (Cloud Functions for Firebase)

Question

I\'m using Firebase Functions with https triggers, and I was wondering how long after sending the response to the client, the functions keeps executing. I want to send a res

Answer 1

If the expected response is not pegged to the outcome of the execution, then you can use

module.exports.doSomeJob = functions.https.onRequest((req, res) => {
res.write('SUCCESS')
return doSomeAsyncJob()
.then(() => {
    emailSender.sendEmail();
})
.then(() => {
    res.end();
})
.catch(...);
});

This sends back a response a soon as a request is received, but keeps the function running until res.end() is called Your client can end the connection as soon as a response is received back, but the cloud function will keep running in the background Not sure if this helps, but it might be a workaround where the client needs a response within a very limited time, considering that executing pub/sub requires some extra processing on its own and takes time to execute
