How to run a Java app which uses npm on AWS Lambda

I have a AWS Lambda written in Spring Boot. The Spring Boot code makes use of a Process to execute a npm command.

This is perfectly fine when running on a server as I can globally install npm packages.

What's the best way to get this working in a lambda?

I toyed around with https://github.com/awslabs/aws-lambda-container-image-converter attempting to create a custom runtime environment which has both Java and the npm package I need. However I wasn't able to get very far due to lack of understanding. I'm even sure if this is the right tool to be using.

So, how can I run both a Java application and execute a npm command in a single lambda?

I believe there are only two options:

  • Use a AWS Layers with npm binary. As you mentioned you can use a custom runtime or add a new layer to your existing lambda function.

  • Invoke another lambda function with nodejs runtime synchronously and capture the response. Check java SDK method for Invoke endpoint

Depending on your particular problem, there also a 3rd option to convert your nodejs library into a executable binary using nexe or a similar library
