Google Cloud Datastore: Node.js Client

Cloud Datastore is a NoSQL document database built for automatic scaling, high performance, and ease of application development. While the Cloud Datastore interface has many of the same features as traditional databases, as a NoSQL database it differs from them in the way it describes relationships between data objects.

Using the client library

1. Select or create a Cloud Platform project.

2. Enable billing for your project.

3. Enable the Google Cloud Datastore API.

4. Set up authentication with a service account so you can access the API from your local workstation.

5. Install the client library:

    npm install --save @google-cloud/datastore
   

6. Try an example:

// Imports the Google Cloud client libraryconst{Datastore}=require('@google-cloud/datastore');asyncfunctionquickStart(){// Your Google Cloud Platform project IDconstprojectId='YOUR_PROJECT_ID';// Creates a clientconstdatastore=newDatastore({projectId: projectId,});// The kind for the new entityconstkind='Task';// The name/ID for the new entityconstname='sampletask1';// The Cloud Datastore key for the new entityconsttaskKey=datastore.key([kind,name]);// Prepares the new entityconsttask={key: taskKey,data: {description: 'Buy milk',},};// Saves the entityawaitdatastore.save(task);console.log(`Saved ${task.key.name}: ${task.data.description}`);}quickStart().catch(console.error);

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
