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

const params = {
    DatabaseName: "testDbFromNode"
};

const command = new CreateDatabaseCommand(params);

try {
    const data = await writeClient.send(command);
    console.log(`Database ${data.Database.DatabaseName} created successfully`);
} catch (error) {
    if (error.code === 'ConflictException') {
        console.log(`Database ${params.DatabaseName} already exists. Skipping creation.`);
    } else {
        console.log("Error creating database", error);

以下代码段使用适用于 JavaScript V2 的 Amazon SDK 风格。它基于 Node.js 示例 Amazon Timestream 中的示例 LiveAnalytics 应用程序，供其上使用。 GitHub
