Deploy and Test

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

2. Clone this repository:

    git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
    cd nodejs-docs-samples/functions/datastore
   

3. Create a Cloud Storage Bucket to stage our deployment:

    gsutil mb gs://[YOUR_BUCKET_NAME]
   

   • Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.

4. Ensure the Cloud Datastore API is enabled:

1. Deploy the "ds-get" function with an HTTP trigger:

    gcloud alpha functions deploy ds-get --bucket [YOUR_BUCKET_NAME] --trigger-http --entry-point get
   

   • Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.

2. Deploy the "ds-set" function with an HTTP trigger:

    gcloud alpha functions deploy ds-set --bucket [YOUR_BUCKET_NAME] --trigger-http --entry-point set
   

   • Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.

3. Deploy the "ds-del" function with an HTTP trigger:

    gcloud alpha functions deploy ds-del --bucket [YOUR_BUCKET_NAME] --trigger-http --entry-point del
   

   • Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.

4. 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!"}}'
   

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

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

6. Call the "ds-del" function to delete the entity:

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

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

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