# 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

```js

const { setup, createDao } = require('google-cloud-datastore-node');

setup({

    projectId: 'my-awesome-project'

});

```

### Creating an entity

```js

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

```js

const { setup, createDao } = require('google-cloud-datastore-node');

const testDao = createDao('Test');

testDao.read('').then((data) => {

    console.log(data);

}).catch(err => console.error(err));

```

### Updating an entity

```js

const { setup, createDao } = require('google-cloud-datastore-node');

const testDao = createDao('Test');

testDao.update('', {

    firstname: 'John',

    lastname: 'Tester'

}).then(() => {

    console.log('Entry has been updated!');

}).catch(err => console.error(err));

```

### Deleting an entity

```js

const { setup, createDao } = require('google-cloud-datastore-node');

const testDao = createDao('Test');

testDao.delete('').then(() => {

    console.log('Entry has been deleted!');

});

```

### Listing entities

```js

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

```js

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 */

    console.log(data);

});

```
