Google Cloud Functions is a scalable pay-as-you-go functions as a service (FaaS) to run your code with zero server management. In the last year, the serverless team has open sourced 7 function frameworks (libraries) that power Cloud Functions in 7 languages.

Let’s give a brief overview of them:

Node 🔗

npm i @google-cloud/functions-framework

• Uses Express’ (request, response) pattern
• Supports Promises, great for non-blocking I/O

Python 🔗

pip install functions-framework

• Uses Flask, Gunicorn as an HTTP server

Go 🔗

import "github.com/GoogleCloudPlatform/functions-framework-go/funcframework"

• Uses Go’s native HTTP package
• Support CloudEvents via the CloudEvent SDK

Java 🔗

mvn install -DgroupId="com.google.cloud.functions" -DartifactId="functions-framework-api" -Dversion="1.0.2" …

In 5 minutes, we’re going to quickly and securely integrate the Google Sheets API to your Cloud Run app. Just copy & paste the documented scripts below.

TL;DR

1. Download service account credentials
2. Share Google Sheet with the service account email
3. Enable the Google Sheets API
4. Write some Node
5. Deploy to Cloud Run

Step 1: Download Credentials 🤖

Create a service account and download a key in a new file called creds.json.

This credential has the unique id: sa-name@$PROJECT.iam.gserviceaccount.com

2. Share Google Sheet with Service Account 🔗

Create a new Google Sheet if you don’t have one already: sheets.new …

🅡 is a programming language and environment commonly used for statistical computing, data analytics and scientific research.

The R Functions Framework allows you to write portable R functions that can be easily deployed to Cloud Run.

In this blogpost, we’ll walk through deploying an R service to Cloud Run!

Install R

Install the precompiled binary distribution of R for your operating system at https://cloud.r-project.org/.

This will install the R language and rscript CLI.

Install the R extension in VS Code

For easy local testing of R in our IDE, install the R extension from the VS Marketplace:

Test locally

Open the VS Code command palette (⌘⇧P) and type:

R: Run Command in…

Swift (🔗) is an innovative, open source programming language developed by Apple to make software everywhere safer, faster, and more fun to create.

Vapor (vapor.codes) is a non-blocking, event-driven architecture built on top of Apple’s SwiftNIO, written in Swift with a focus on type-safety.

Together, you can build powerful web services that can be hosted on top of Cloud Run. This blogpost will give you a quick start for doing just that.

Prerequisites

To use Swift, you need one tool, Xcode. …

The Cloud SDK includes a set of tools and libraries for interacting with Google Cloud products and services, with the gcloud CLI tool being the primary command.

Here are a few commands/tricks that I use frequently:

1. Prevent Prompts. Set Defaults.

Setting default configurations for your gcloud CLI prevents the Y/n prompt:

gcloud config set compute/region us-west1
gcloud config set run/platform managed

See your existing configs with gcloud config list or see all configs 📄.

2. Getting / Change Project IDs

When using gcloud, most commands make API requests using the currently configured project. Some commands require the project name in the command arguments.

I like to keep the current project in an environment variable like…

Introducing the .NET Functions Framework.

In this blogpost, we’ll give an introduction to the .NET Functions Framework and show you how to easily deploy a secure function on Google Cloud.

Setup

Install the .NET Core SDK 3.1.

After installing, you should have access to the CLI, dotnet including handy .NET templates to quickly get started.

Quickstart

Install the Google Cloud Functions template package into the .NET tooling:

dotnet new -i Google.Cloud.Functions.Templates::1.0.0-alpha07

Then create a new HTTP function using the .NET template:

mkdir HelloFunctions
cd HelloFunctions
dotnet new gcf-http

This will create HelloFunctions.csproj and Function.cs in the current directory.

Test Locally

Run the function locally:

dotnet…

🦕 Deno (deno.land) is a secure TypeScript runtime built on V8 and Rust, created by Ryan Dahl, the creator of Node.js.

🏃 Cloud Run (cloud.run) is a fully managed compute platform that automatically scales your stateless containers.

In this blogpost, we’ll show you how to containerize and deploy a simple Deno application on Cloud Run, running a serverless, HTTPS, TypeScript service.

Create a Deno App

Let’s create a web application in TypeScript for Deno:

Install Deno

Install Deno on your system using the instructions on the official site:

curl -fsSL https://deno.land/x/install/install.sh | sh

Create a main.ts file

Create a simple HTTP server using Deno’s standard library:

You’ll notice non-Node features like import and top-level for await. …

Introducing the Ruby Functions Framework. This gem allow you to easily write ruby services with a simple functions as a service developer experience. In this blogpost, we’ll walk through how use the Ruby Functions Framework to containerize and deploy a Ruby method to Cloud Run.

Setup

Ensure Ruby 2.4+ is installed with ruby -v. 🔗

Create a Gemfile with the following contents:

source "https://rubygems.org"
gem "functions_framework", "~> 0.1"

Create a Function

Create a file called app.rb with the following function called hello:

Test your Function

Test your function by installing dependencies and starting your web server:

Go to localhost:8080 to see your function response! …
