Question

I am currently working on a Firebase function. As I am still in the development stage, I have a number of logs in my code to see what's going on.

async function getAddressByIdAsync(address) {

    let addr = addressesRef.child(address);
    console.log(addr);

    return admin.database().ref('Addresses/' + address);
}

The only way I have found to be able to see these logs in real time is though the Firebase console, which is very slow and generally a bad UI experience IMO.

I'm looking for a command line solution that will let me see in real time the logs coming from the Firebase cloud function.

I have tried this command

firebase functions:log

Which appears to return the last twenty or so log entries into my Firebase Functions.

I know Google Cloud has a tail option on the end of that CLI but it doesn't work here.

firebase functions:log tail

Error: Too many arguments. Run firebase help functions:log for usage instructions

Is there a way to get a live running output of the logs from firebase cloud functions?

What about using gcloud? https://cloud.google.com/functions/docs/monitoring/logging#using_the_command-line_tool. See also https://stackoverflow.com/a/44556424/3371862 — Renaud Tarnec, Feb 06 '20 at 12:15
Firebase Cloud Functions logs are also available on the Google Cloud console. — Renaud Tarnec, Feb 07 '20 at 07:28

You can try the local emulator, that way you can first run your functions locally (and log in your terminal), before deploying.

Im not sure the emulator will work since the only way i can call this is though the Google Home app as i am testing smart home device. – Linda Lawton - DaImTo Feb 06 '20 at 08:39
