import { TimestreamWriteClient, DeleteDatabaseCommand } from "@aws-sdk/client-timestream-write";
const writeClient = new TimestreamWriteClient({ region: "us-east-1" });

const params = {
    DatabaseName: "testDbFromNode"
};

const command = new DeleteDatabaseCommand(params);

try {
    const data = await writeClient.send(command);
    console.log("Deleted database"); 
} catch (error) {
    if (error.code === 'ResourceNotFoundException') { 
        console.log(`Database ${params.DatabaseName} doesn't exists.`); 
    } else { 
        console.log("Delete database failed.", error); 
        throw error; 
    } 
}

Das folgende Snippet verwendet den AWS SDK for JavaScript V2-Stil. Es basiert auf der Beispielanwendung unter Node.js Beispiel Amazon Timestream für die LiveAnalytics Anwendung auf GitHub.

async function deleteDatabase() { 
    console.log("Deleting Database"); 
    const params = { 
        DatabaseName: constants.DATABASE_NAME 
    }; 
 
    const promise = writeClient.deleteDatabase(params).promise(); 
 
    await promise.then( 
        function (data) { 
            console.log("Deleted database"); 
         }, 
        function(err) { 
            if (err.code === 'ResourceNotFoundException') { 
                console.log(`Database ${params.DatabaseName} doesn't exists.`); 
            } else { 
                console.log("Delete database failed.", err); 
                throw err; 
            } 
        } 
    );
