Cloud Datastore

This recipe shows you how to read and write an entity in Datastore from a Cloud Function. Where applicable:

Replace [PROJECT-ID] with your Cloud Platform project ID

Follow the Cloud Functions quickstart guide to setup Cloud Functions for your project

Clone this repository

cd ~/
git clone https://github.com/jasonpolites/gcf-recipes.git
cd gcf-recipes/datastore

Create a Cloud Storage Bucket to stage our deployment
```
gsutil mb gs://[PROJECT-ID]-gcf-recipes-bucket
```
Ensure the Cloud Datastore API is enabled

Deploy the "ds-get" function with an HTTP trigger

gcloud alpha functions deploy ds-get --bucket [PROJECT-ID]-gcf-recipes-bucket --trigger-http --entry-point get

Deploy the "ds-set" function with an HTTP trigger

gcloud alpha functions deploy ds-set --bucket [PROJECT-ID]-gcf-recipes-bucket --trigger-http --entry-point set

Deploy the "ds-del" function with an HTTP trigger

gcloud alpha functions deploy ds-del --bucket [PROJECT-ID]-gcf-recipes-bucket --trigger-http --entry-point del

Call the "ds-set" function to create a new entity

gcloud alpha functions call ds-set --data '{"kind": "gcf-test", "key": "foobar", "value": {"message": "Hello World!"}}'

Call the "ds-get" function to read the newly created entity

gcloud alpha functions call ds-get --data '{"kind": "gcf-test", "key": "foobar"}'

Call the "ds-del" function to delete the entity

gcloud alpha functions call ds-del --data '{"kind": "gcf-test", "key": "foobar"}'

Call the "ds-get" function again to verify it was deleted

gcloud alpha functions call ds-get --data '{"kind": "gcf-test", "key": "foobar"}'

This recipe comes with a suite of unit tests. To run the tests locally, just use npm test

npm install
npm test

The tests will also produce code coverage reports, written to the /coverage directory. After running the tests, you can view coverage with
