Using async/await

You can use the async/await pattern in your calls to the Amazon SDK for JavaScript. Most functions that take a callback do not return a promise. Since you only use await functions that return a promise, to use the async/await pattern you need to chain the .promise() method to the end of your call, and remove the callback.

The following example uses async/await to list all of your Amazon DynamoDB tables in us-west-2.

var AWS = require("aws-sdk");
//Create an Amazon DynamoDB client service object.
dbClient = new AWS.DynamoDB({ region: "us-west-2" });
// Call DynamoDB to list existing tables
const run = async () => {
  try {
    const results = await dbClient.listTables({}).promise();
    console.log(results.TableNames.join("\n"));
  } catch (err) {
    console.error(err);
  }
};
run();
