Typescript template cannot resolve aws-sdk modules

I am using the aws-nodejs-typescript template. Everything works fine but when I try to import aws-sdk I get 3 Module not found errors.

import { failure, success } from '../../../libs/response';

import { APIGatewayProxyHandler } from 'aws-lambda';

import { DynamoDB } from 'aws-sdk';

const dynamoDb = new DynamoDB.DocumentClient();

export const handler: APIGatewayProxyHandler = async () => {

  try {

    const params = {

      TableName: 'My_Table',

      Key: {

        pk: 'variable',

        sk: 'variable'

      }

    };

    const result = await dynamoDb.query(params).promise();

    return success(result);

  } catch (e) {

    return failure();

  }

};

Are types missing? Types are already included in aws-sdk so I don’t need to install @types/aws-sdk.

When I browse my node_modules folder everything is there including types.

The problem is in the webpack config. Add .js into the resolve.extensions array.

resolve: { extensions: ['.mjs', '.json', '.ts'] }
