Before you start

Create a serverless database in Yandex.Cloud.
In the properties of the created database, on the Overview tab, find and copy the Document API endpoint value.
Install the developer's tools by running the command npm install yandex-cloud.

Creating a table

const { DocAPIService } = require('yandex-cloud')

// change for your Document API endpoint
const endpoint = '<your Document API endpoint here>';
const docapi = new DocAPIService(endpoint)

var params =
{
  TableName: "test/pets",
  AttributeDefinitions:
  [
    {
      AttributeName: "species",
      AttributeType: "S"
    },
    {
      AttributeName: "name",
      AttributeType: "S"
    }
  ],
  KeySchema:
  [
    {
      AttributeName: "species",
      KeyType: "HASH"
    },
    {
      AttributeName: "name",
      KeyType: "RANGE"
    }
  ]
};
docapi.createTable(params).then(res => { console.log(res); }).catch(err => { console.log(err); });

Saving writes

const { DocAPIService } = require('yandex-cloud')

// change for your Document API endpoint
const endpoint = '<your Document API endpoint here>';
const docapi = new DocAPIService(endpoint)

var params =
{
  TableName: "test/pets",
  Item:
  {
    "species": "cat",
    "name": "Tom",
    "color": "Black",
    "price": "10.5"
  }
};
docapi.putItem(params).then(res => { console.log(res); }).catch(err => { console.log(err); });

Reading writes

const { DocAPIService } = require('yandex-cloud')

// change for your Document API endpoint
const endpoint = '<your Document API endpoint here>';
const docapi = new DocAPIService(endpoint)

var params =
{
  TableName: "test/pets",
  Key:
  {
    "species": "cat",
    "name": "Tom"
  }
};
docapi.getItem(params).then(res => { console.log(res); }).catch(err => console.log(err));
