Google Cloud Functions using GO

This project has examples for using Go Cloud Function and Firestore

The project is separated into 2 directories

• /functions - for Cloud Function
• //events - Event triggered functions
• //http - HTTP triggered functions
• /firestore - for non Cloud Function code i.e. can be run on a local machine

Function triggers are:

• HTTP
• Events (firestore)

Also includes a demonstration of interacting with Firestore outside of Cloud Functions

The functions are designed to work together to create a simple people application

In the database people are located in a root collection /people and a person is added as a document in the collection e.g. /people/SYd2omJqJnoahIgqtdgs/. A person includes the follow firestore data:

Key	Type
createdAt	timestamp
dob	timestamp
firstname	string
lastname	string
postcode	string
location	geopoint

The http function AddPerson takes the following json payload and creates a new person in the DB

{
	"fname": "Maurice",
	"lname": "Moss",
	"dob": "1980-04-20T00:00:00.000Z",
	"postcode": "E1 1AB"
}

The event function UpdateLocation will respond to write events on the person document and fetch the Latitude/Longitude for the postcode using postcodes api

The firestore application can be run locally and provides an example of querying firestore and extracting a document by ID you will need to set 2 environment variables

• GCLOUD_PROJECT: (GCP project id)
• GCLOUD_SERVICE_ACCOUNT_PATH: (path to local json service account which has firestore access) build the program go build and run providing a query id and a string to query lastname for ./firestore iLI2lKSyha8HMGpNCyO7 Moss
