Merging pdfs using aws lambda

Question

I currently have a nodejs project that generates pdfs using puppeteer. I now want to merge the generated pdfs into a single pdf. There are npm libraries like easy-pdf-merge and pdfmerger available. The issue is we would want to host our project in AWS Lambda. Can these libraries run in a Lambda as a nodejs application given they require Java 6 or higher? If not, what would be the best approach to merge pdfs within a lambda?

Answer 1

You'll probably need to use layers. You can start with a node.js lambda and add a layer for your java needs.

You can check this github repo for publicly available lambda layers. There's one for java 11.
