DynamoDB: Query JSON (Guide w/ Code Examples)

Provided by Rafal Wilinski
JavaScript AWS SDK does not provide a specific method to query data as JSON. But you can use the query
operation to get data as an array and pass the result to JSON.stringify
method to convert the array to a JSON string.
const AWS = require('aws-sdk'); const dynamoDb = new AWS.DynamoDB.DocumentClient(); const params = { TableName: 'tableName', KeyConditionExpression: 'primaryKey = :primaryKeyValue', ExpressionAttributeValues: { ':primaryKeyValue': 'value' } }; dynamoDb.query(params, (error, data) => { if (error) { console.error(error); return; } console.log(JSON.stringify(data.Items)); });
