AWS Announces Node.js 14 Support for Its Function as a Service, Lambda

Recently AWS announced Node.js version 14 support for its Function as a Service (FaaS), Lambda. Developers can now author AWS Lambda functions using Node.js' new features, such as top-level-await, enhanced diagnostics, modifications of the streams APIs, and a revised JavaScript engine for better performance.

Recently AWS announced Node.js version 14 support for its Function as a Service (FaaS), Lambda. Developers can now author AWS Lambda functions using Node.js' new features, such as top-level-await, enhanced diagnostics, modifications of the streams APIs, and a revised JavaScript engine for better performance.

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 nodejs14.x when creating or updating functions or by using the appropriate managed runtime base image. Node.js 14 is powered by V8 version 8.1, a significant upgrade from the V8 7.4 engine powering the previous Node.js 12.x and brings new features such as operators Nullish Coalescing and Optional Chaining.

Jeremy Daly, AWS Hero, said in a tweet:

Yessa, Node.js 14.x now on Lambda! This means you can now use Nullish Coalescing, which is something you never knew you needed but can't possibly live without now that you have it!

const newVersion = null ?? 'this works great' ;
console.log(newVersion);
// expected output: "this works great"

const nullishTest = 0 ?? 36;
console.log(nullishTest);
// expected output: 0 because 0 is not the same as null or undefined
