Lambda function error on importing AWS in Nodejs

Question

I'm trying to import the AWS into the Lambda function, and use that to add a new object to a DynamoDB table. (Nodejs version: 18)

I tried many options to import the AWS:

const AWS = require('aws-sdk');

import AWS from '/var/runtime/node_modules/aws-sdk/lib/aws.js'

import AWS from 'aws-sdk';

import { DynamoDB } from '@aws-sdk/dynamodb';

But neither of them worked out for me, and every time it got me a message similar to this: "Cannot find package '<package_name>' imported from "

(or for the "require" option, I've got "require is not defined in ES module scope, you can use import instead")

Answer 1

Use:

import { DynamoDB } from '@aws-sdk/dynamodb';

But also rename your index.js file to index.mjs, that should do the trick.
