Answer 1

To safely use firebase npm package (version 3.3.0) in AWS Lambda (Nodejs 4.3), Please do the following:

'use strict';

var firebase = require("firebase");

exports.handler = (event, context, callback) => {
    context.callbackWaitsForEmptyEventLoop = false;  //<---Important

    var config = {
        apiKey: "<>",
        authDomain: "<>.firebaseapp.com",
        databaseURL: "https://<>.firebaseio.com",
        storageBucket: "<>.appspot.com",
    };

    if(firebase.apps.length == 0) {   // <---Important!!! In lambda, it will cause double initialization.
        firebase.initializeApp(config);
    }

    ...
    
    ...
};
