Access Oracle database from AWS Lambda NodeJS Application

How to package Oracle Client Libraries with your NodeJS application and run on AWS Lambda

You will need

• Node 10.16.x. (Newer node version may not help because you may not easily find compatible oracledb package)
• NPM oracledb package
• Oracle Instant Client light linux version zip file

Let us assume your current working directory contains the lambda code in index.js, but ultimately your dist folder will contain all the files that are to be deployed to lambda.

Your zip file contents should look similar to below.

dist folder contents

dist/lib folder contents

Upload the zip file created to s3. Have your lambda use the zip deployment package from s3.
