AWS Lambda
Developer Guide

Programming Model(Node.js)

AWS Lambda currently supports the following Node.js runtimes:

  • Node.js runtime v8.10 (runtime = nodejs8.10)

  • Node.js runtime v6.10 (runtime = nodejs6.10)

  • Node.js runtime v4.3 (runtime = nodejs4.3)*

    *Deprecated

When you create a Lambda function, you specify the runtime that you want to use. For more information, see runtime parameter of CreateFunction.

The following sections explain how common programming patterns and core concepts apply when authoring Lambda function code in Node.js. The programming model described in the following sections applies to all supported runtime versions, except where indicated.
