Google Cloud Functions Cloud Datastore sample

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

View the source code.

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 here and in subsequent commands with the name of your Cloud Storage Bucket.

  4. Ensure the Cloud Datastore API is enabled:

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

     gcloud alpha functions deploy get --stage-bucket YOUR_BUCKET_NAME --trigger-http

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

     gcloud alpha functions deploy set --stage-bucket YOUR_BUCKET_NAME --trigger-http

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

     gcloud alpha functions deploy del --stage-bucket YOUR_BUCKET_NAME --trigger-http

  4. Call the "set" function to create a new entity:

     gcloud alpha functions call set --data '{"kind":"Task","key":"sampletask1","value":{"description":"Buy milk"}}'

    or

     curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1","value":{"description":"Buy milk"}}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/set"
    • Replace [YOUR_REGION] with the region where your function is deployed.
    • Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

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

     gcloud alpha functions call get --data '{"kind":"Task","key":"sampletask1"}'

    or

     curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/get"
    • Replace [YOUR_REGION] with the region where your function is deployed.
    • Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

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

     gcloud alpha functions call del --data '{"kind":"Task","key":"sampletask1"}'

    or

     curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/del"
    • Replace [YOUR_REGION] with the region where your function is deployed.
    • Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

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

     gcloud alpha functions call get --data '{"kind":"Task","key":"sampletask1"}'

    or

     curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/get"
    • Replace [YOUR_REGION] with the region where your function is deployed.
    • Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.
