从Node.js（Seneca）连接到Google Cloud Datastore

Question

I am trying to connect to the Google Cloud Datastore using node.js and the data layer functionality present in the Seneca framework. The Seneca framework needs to create a connection to a database as per connecting to a database instance, passing information like:

name: '',
host: '',
port: ,
username: '',
password: ''

etc.

Is there a way to connect to a Google Datastore like a typcal database instance or is the only way through REST api calls?

Answer 1

Authentication support for Google Cloud Datastore is currently limited to OAuth 2.0. See Getting started with Google Cloud Datastore and Node.js .

The credentials are passed along in each HTTP request.

Answer 2

At the moment, the only way to connect to the Google Cloud Datastore, using node.js, is by using the REST API.

Using the google-api-nodejs-client you can get access to a datastore object:

googleapis.discover('datastore', 'v1beta2')
    .withAuthClient(authCredentials)
    .execute(function(err, client) {
      if (err) {
        seneca.log.error(err);
      }
      datastore = client.datastore.withDefaultParams({
        datasetId: datasetid}).datasets;
    });

This object will be like your connection object and you can use this object to make queries to your datastore.
