Firebase cloud functions: sending multiple messages

[Ankit Jaiswal]

I'm trying to send multiple notifications from one cloud function. There are two use cases:

1. In a group chat, I've to create two separate payloads for android and iOS devices and then send notifications through the same cloud function for both the payloads.

2. There is a specific case, wherein, on an event on a collection, I need to send multiple messages to the same recipient. 

I tried with the below code:

var promises = new Array();

            if (androidMemberToken.length > 0) {

            var androidPromise = admin.messaging().sendToDevice(androidMemberToken, payload, options)

                .then(function(response) {

                    console.log("Message sent: ", response);

                })

                .catch(function(error) {

                    console.log("Error sending message: ", error, payload);

                });

            promises.push(androidPromise);

            }

            if (iosMemberToken.length > 0) {

            payload['notification'] = info;

            var iosPromise = admin.messaging().sendToDevice(iosMemberToken, payload, options)

                .then(function(response) {

                    console.log("Message sent: ", response);

                })

                .catch(function(error) {

                    console.log("Error sending message: ", error, payload);

                });

            promises.push(iosPromise);

            }

            

            return Promise.all(promises); 

This is for group chat. I'm not getting any error message, however the notifications are not sent. Cloud Function logs do not show any success/error messages. What should be the correct approach for the above two cases for sending multiple notifications?

Hi Ankit,

Did you verify those code blocks get executed? I.e. are iosMemberToken.length and androidMemberToken.length actually greater than zero? Did you confirm the function is actually invoked?

Thanks Kato, indeed there was some issue with the logic and token arrays were not populated correctly because of that. Code is working fine now.
