As developers we often come across situations where we’d like to see all the remote API calls made by a certain application. This requirement often comes up during development and testing, but there are times when you might want to see this information for production applications too.
In this article we explore a couple of simple tricks for logging the HTTP requests made by applications written in Node.js or Python. These techniques do not require any specific logging framework, and can be managed entirely within the application code without too much effort. I’m going to use the Firebase Admin SDK…
Firebase Admin SDK contains APIs for fetching and deleting individual user accounts. These APIs enable developers to fetch Firebase Auth user accounts by their uid, email or phone number, or delete a selected user account by its uid. Developers have been using these APIs to implement tools, automation scripts and even Cloud Functions that perform complex user management tasks. Listing 1 shows a Node.js script that uses the Admin SDK to fetch a user account by email address, and delete it.
While these APIs are useful in a wide range of…
Cloud Firestore is Google’s highly scalable, NoSQL database for mobile and web applications. On top of a document-oriented data model, Firestore offers an array of powerful features including realtime event listeners, atomic transactions, and offline support.
Just because it is another NoSQL database, many developers assume that you cannot enforce any integrity constraints on Firestore data. But that is not entirely correct. In this article we look at Firestore’s data model, the constraints we can apply on Firestore data, and the programming semantics that result from such constraints. …
Google Cloud Identity Platform (GCIP) allows you to add Google-grade identity and access management support to your own applications. Enterprises can use GCIP to manage the identities of their employees, customers, partners and IoT devices at scale. In November 2019 Google further extended GCIP with support for tenant management. This new feature enables enterprises to define multiple tenants within a single instance of GCIP. Each user account can be assigned to a tenant, and authenticated using a collection of tenant-specific identity providers.
As an example consider an automobile manufacturer who’s partnered with at least two distributors. The manufacturer offers an…
Recently I was reading Patrick Martin’s article on deploying a C# backend in Google Cloud Run, and I figured it would be fun to write a follow up piece featuring the Firebase Admin SDK for .NET. Hence, in this post I show how to implement a custom authentication service in C#, and deploy it as a serverless API using Cloud Run. This service validates user credentials, and uses the Admin SDK to generate signed custom tokens that clients can use to sign into Firebase.
Google Cloud Run is one of the latest additions to Google’s serverless portfolio. It enables developers…

We’ve all received emails of this nature from various online services. It is a simple yet effective way to interact with the users, and get them to take certain actions. …
Since the Firebase Cloud Messaging (FCM) support became available across all flavors of the Admin SDK, many developers have been requesting for an API that enables sending messages to more than one recipient. The original FCM API, which is demonstrated in listing 1, facilitates sending messages to individual devices by addressing each message to a single device registration token.
But developers often come across scenarios where a certain message needs to be sent to multiple devices. I myself ran into this use case when I was working on my cryptocurrency price…
The Go runtime for Google Cloud Functions was released into beta this month. I’m a huge fan of statically typed languages, and of Golang in particular. Therefore I’m excited about the possibility of developing serverless functions in Go, and deploying them on the Google Cloud Platform (GCP). In this post we look at how to implement a Cloud Function in Go, and set it up to be called from a Cloud Firestore trigger. Then we are going to make things more interesting by throwing the Firebase Realtime Database also into the mix.
In this article I demonstrate how to build a cryptocurrency price monitoring app using Firebase and Google Cloud Platform (GCP). The app receives notifications whenever the price of Bitcoin or Ethereum change in the market. Users can configure minimum and maximum price thresholds for each cryptocurrency, and we use these settings to determine which users to notify for any given price change.
The inspiration for this app came from an article published by the Pusher community (read part 1 and part 2 here). Their cryptocurrency price alerts app uses Pusher for delivering notifications, which seems to be using Firebase Cloud…
Enterprise developers often have to deploy their applications behind a corporate HTTP proxy in order to meet various security and IT compliance requirements. This means applications that depend on Google Cloud Platform (GCP) libraries and Firebase Admin SDKs should be configured to make all outgoing service requests through a proxy. In this post we explore how to achieve this in several programming languages. We will focus on Firebase services that are typically accessed through a REST interface, as well as Cloud Firestore, which is accessed over gRPC. …
