google-cloud-datastore-node

NodeJS library to simplify working with Google Cloud DataStore

Based on a code by Google https://github.com/GoogleCloudPlatform/nodejs-getting-started

The difference is that this library uses Promises instead of callbacks which leads to a better code organization and can be used as well with async/await.

Installation

yarn add google-cloud-datastore-node

Usage

Setting up project id

const { setup, createDao } = require('google-cloud-datastore-node');
 
setup({
    projectId: 'my-awesome-project'
});

Creating an entity

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
testDao.create({
    firstname: 'John',
    lastname: 'Tester'
}).then(() => {
    console.log('Entry has been created!');
}).catch(err => console.error(err));

Reading an entity

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
testDao.read('<ID>').then((data) => {
    console.log(data);
}).catch(err => console.error(err));

Updating an entity

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
testDao.update('<ID>', {
    firstname: 'John',
    lastname: 'Tester'
}).then(() => {
    console.log('Entry has been updated!');
}).catch(err => console.error(err));

Deleting an entity

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
testDao.delete('<ID>').then(() => {
    console.log('Entry has been deleted!');
});

Listing entities

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
/* parameters are `limit`, `order`, `token` */
testDao.list(10, 'test').then(({ data, hasMore }) => {
    /* `hasMore` can be re-used as a `token` param in case of pagination implementation */
    console.log(data);
});

Listing entities with filters applied

const { setup, createDao } = require('google-cloud-datastore-node');
 
const testDao = createDao('Test');
 
/* parameters are `filters`, `limit`, `order`, `token` */
testDao.listBy([
    ['location', 'CA']
], 10, 'test').then(({ data, hasMore }) => {
    /* `hasMore` can be re-used as a `token` param in case of pagination implementation */
