Particle –> Google Cloud Pub/Sub –> Datastore Tutorial

This tutorial code is intended to allow data to flow from Google Cloud Pub/Sub to Google Cloud Datastore. This is part of a larger tutorial for sending data from Particle devices into a hosted database.

You can find the full documentation on the Particle <> Google Cloud integration on our docs .

Prerequisites

Before this script will become useful to you, please make sure you have done all of the following:

1) Have Particle device(s) collecting data and publishing events

2) Have a Google Cloud Platform account with a project and a Pub/Sub topic

3) Enabled the Google Cloud Platform integration on Particle

4) Created a Google Cloud Platform private key

5) Created a Google Cloud Pub/Sub subscription

For all required steps, check out the full tutorial

Setup and configuration

Clone the repository

git clone https://github.com/spark/google-cloud-datastore-tutorial.git

Add your Private Key

Create a file in the root of your local repository called gcp_private_key.json

Next, paste in the contents of your Google Cloud Platform JSON private key. It should look something like this:

ype": "service_account",
roject_id": "[GOOGLE CLOUD PLATFORM PROJECT ID]",
rivate_key_id": "[PRIVATE_KEY_ID]",
rivate_key": "[PRIVATE_KEY]"
lient_email": "[CLIENT_EMAIL]",
lient_id": "[CLIENT_ID]",
uth_uri": "https://accounts.google.com/o/oauth2/auth",
oken_uri": "https://accounts.google.com/o/oauth2/token",
uth_provider_x509_cert_url": "[CERT_URL]",
lient_x509_cert_url": "[CLIENT_CERT_URL]"

Configure the Script

Open up tutorial.js and update the config object for your Google Cloud Platform configuration:

config = {
gcpProjectId: '[YOUR PROJECT ID]',
gcpPubSubSubscriptionName: '[YOUR PUB/SUB SUBSCRIPTION NAME]',
gcpServiceAccountKeyFilePath: './gcp_private_key.json'

• gcpProjectId: Your Google Cloud Platform Project ID
• gcpPubSubSubscriptionName: Your Google Cloud Platform Pub/Sub topic's subscription name

Running the application

• Install dependencies: npm install
• Run the script: node tutorial.js
