DynamoDB: GetItem (Guide w/ Code Examples)

The AWS SDK for JavaScript provides a getItem method for retrieving an item from a DynamoDB table.

const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB({region: 'us-west-2', apiVersion: '2012-08-10'});

const params = {
    TableName: 'MyTable',
    Key: {
        'PrimaryKey': {S: 'some-value'},
        'SortKey': {N: '123'},
    },
};

dynamodb.getItem(params, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.log(data);
    }
});
