What is @aws-sdk/client-dynamodb?

The @aws-sdk/client-dynamodb npm package is a client library for interacting with Amazon DynamoDB, a NoSQL database service provided by AWS. It allows developers to perform various operations on DynamoDB tables and data, such as creating and deleting tables, reading and writing data, and querying and scanning data.

What are @aws-sdk/client-dynamodb's main functionalities?

Creating a DynamoDB Table

This code sample demonstrates how to create a new DynamoDB table with a specified schema and provisioned throughput.

const { DynamoDBClient, CreateTableCommand } = require('@aws-sdk/client-dynamodb');

const client = new DynamoDBClient({ region: 'us-west-2' });
const createTableParams = {
  TableName: 'MyTable',
  KeySchema: [{ AttributeName: 'id', KeyType: 'HASH' }],
  AttributeDefinitions: [{ AttributeName: 'id', AttributeType: 'S' }],
  ProvisionedThroughput: { ReadCapacityUnits: 5, WriteCapacityUnits: 5 }
};

const createTableCommand = new CreateTableCommand(createTableParams);
client.send(createTableCommand).then((data) => console.log(data)).catch((error) => console.error(error));

Inserting Data into a DynamoDB Table

This code sample shows how to insert a new item into a DynamoDB table.

const { DynamoDBClient, PutItemCommand } = require('@aws-sdk/client-dynamodb');

const client = new DynamoDBClient({ region: 'us-west-2' });
const putItemParams = {
  TableName: 'MyTable',
  Item: {
    'id': { S: '123' },
    'data': { S: 'Some data' }
  }
};

const putItemCommand = new PutItemCommand(putItemParams);
client.send(putItemCommand).then((data) => console.log(data)).catch((error) => console.error(error));

Querying Data from a DynamoDB Table

This code sample illustrates how to query a DynamoDB table for items with a specific key.

const { DynamoDBClient, QueryCommand } = require('@aws-sdk/client-dynamodb');

const client = new DynamoDBClient({ region: 'us-west-2' });
const queryParams = {
  TableName: 'MyTable',
  KeyConditionExpression: 'id = :idValue',
  ExpressionAttributeValues: {
    ':idValue': { S: '123' }
  }
};

const queryCommand = new QueryCommand(queryParams);
client.send(queryCommand).then((data) => console.log(data.Items)).catch((error) => console.error(error));
