Introduction

Cloud Functions come in two distinct variants: foreground (HTTP) and background. You invoke HTTP functions from standard HTTP requests.You can use background functions to handle events from your Cloud infrastructure, such as messages on a Google Cloud Pub/Sub topic, or changes in a Google Cloud Storage bucket. This project includes three example functions:

• helloWorldHTTP - foreground (HTTP) function
• helloWorldPubSub - background functions to handle Google Cloud Pub/Sub topic events
• helloWorldStorage - background functions to handle events from Google Cloud Storage bucket

Clone project

Clone project from GitHub:

git clone https://github.com/amsokol/gcp-cloud-functions-typescript-starter.git

Go to to project folder:

cd gcp-cloud-functions-typescript-starter

Optional. You can open project in Visual Studio Code to to build and deploy project from GUI menu:

code .

Build project (command-line)

If you prefer command-line interface instead of Visual Studio Code than use the next commands to build project.

Install required npm modules:

npm install

Compile TypeScript Cloud Function:

tsc

File index.js is generated and is ready to deploy to Cloud Functions

Deploy project to Cloud Functions Local Emulator (command-line)

If you prefer command-line interface instead of Visual Studio Code than use the next commands to deploy project.

The Cloud Functions Emulator is distributed as a standard NPM package, so you can install it with a standard npm install command:

npm install -g @google-cloud/functions-emulator

Before you can deploy a function, you need to start the Emulator as follows:

functions start

Deploy an HTTP helloWorld function to the Emulator as follows:

npm run deploy-local

Open helloWorld link in browser to see results.

See Cloud Functions Local Emulator for more details.

Build bundle to deploy to Google Cloud Platform (command-line)

If you prefer command-line interface instead of Visual Studio Code than use the next commands to create zip archive for deployment.

For Windows using PowerShell:

npm run package-zip(windows)

For Linux/Unix using zip utility (you have to install it before):

npm run package-zip(linux)

It creates helloWorld.zip that includes index.js, package.json, settings.json files. helloWorld.zip is ready to be deployed to Google Cloud Platform.

See Deploying from Your Local Machine for more details.
