Prerequisite tasks

To set up and run this example, you must first complete these tasks:

  • Set up the project environment to run these Node TypeScript examples, and install the required AWS SDK for JavaScript and third-party modules. Follow the instructions on GitHub.

  • Create a shared configurations file with your user credentials. For more information about providing a credentials JSON file, see Loading credentials in Node.js from the shared credentials file.


This example uses CommonJS sytax, as Lambda does not currently support ECMAScript 6 (ES6) syntax. For more information, see JavaScript ES6/CommonJS syntax
