The AWS SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the AWS SDK for JavaScript version 3 (V3).
Using async/await
Rather than using promises, you should consider using async/await. Async functions are simpler and take less boilerplate than using promises. Await can only be used in an async function to asynchronously wait for a value.
The following example uses async/await to list all of your Amazon DynamoDB tables in
us-west-2
.
For this example to run:
Install the AWS SDK for JavaScript DynamoDB client by entering
npm install @aws-sdk/client-dynamodb
in the command line of your project.Ensure you have configured your AWS credentials correctly. For more information, see Loading credentials in Node.js from the shared credentials file.
import { DynamoDBClient, ListTablesCommand } from "@aws-sdk/client-dynamodb"; (async function () { const dbClient = new DynamoDBClient({ region: "us-west-2" }); const command = new ListTablesCommand({}); try { const results = await dbClient.send(command); console.log(results.TableNames.join('\n')); } catch (err) { console.error(err) } })();
Not all browsers support async/await. See Async functions
