Create the client in a separate module and export it.

import { SNSClient } from "@aws-sdk/client-sns"; // The AWS Region can be provided here using the `region` property. If you leave it blank // the SDK will default to the region set in your AWS config. export const snsClient = new SNSClient({});

Import the SDK and client modules and call the API.

import { CheckIfPhoneNumberIsOptedOutCommand } from "@aws-sdk/client-sns"; import { snsClient } from "../libs/snsClient.js"; export const checkIfPhoneNumberIsOptedOut = async ( phoneNumber = "5555555555", ) => { const command = new CheckIfPhoneNumberIsOptedOutCommand({ phoneNumber, }); const response = await snsClient.send(command); console.log(response); // { // '$metadata': { // httpStatusCode: 200, // requestId: '3341c28a-cdc8-5b39-a3ee-9fb0ee125732', // extendedRequestId: undefined, // cfId: undefined, // attempts: 1, // totalRetryDelay: 0 // }, // isOptedOut: false // } return response; };
