AWS Lambda Now Has Support for Node.js 16 Runtime

by Reima Budd on May 30, 2022 Software 482 Views

Recently AWS announced that Node.js version 16 supports its Function as a Service (FaaS) AWS Lambda and is in active LTS status (ready for general use).

Developers can now author AWS Lambda functions using Node.js' new features, such as toolchain and compiler upgrades (including prebuilt binaries for Apple Silicon), stable timers promises API, and RegExp match indices, and faster calls with argument size mismatch.

AWS Lambda supports the current Long Term Support (LTS) version of Node.js, which means developers who want to use the new versions need to specify a runtime parameter value of nodejs16.x when creating or updating functions or by using the appropriate managed runtime base image. Furthermore, the Node.js 16 runtime is supported by functions running on either Arm-based AWS Graviton2 processors or x86-based processors.

The Node.js 16 version includes support for ES modules and top-level await added to the Node.js 14 runtime in January 2022, which is useful when used with Provisioned Concurrency to reduce cold start times. 

The Node.js 16 managed runtimes and container base images bundle the AWS JavaScript SDK version 2Dan Fox, principal specialist solutions architect, Serverless at AWS, explains the benefit of the SDK in a recent AWS Compute blog post:

Using the bundled SDK is convenient for a few use cases. For example, developers writing short functions via the Lambda console or inline functions via CloudFormation templates may find it useful to reference the bundled SDK.

Earlier, the Node.js runtime available in AWS Lambda was 14 and has been in Maintenance LTS since October 2021. It will reach the end of life in eleven months.
