React Router v7 Framework Instrumentation instructions using AWS CDK Lambda NodejsFunction

[MattyBalaam]

Problem Statement

I’ve been really struggling to work out how to add instrumentation to an app built using aws-cdk-lib/aws-lambda-nodejs and NodejsFunction.

Basically this bundles up all the files using esbuild and puts them into an output directory and I have been trying to use '-import ./instrument.server.mjs' on NODE_OPTIONS, but to use this we then need to copy over instrument.server.mjs to the output folder. However this opens up a new problem wherbey there are missing node_modules.

Solution Brainstorm

Solutions I have tried:

• Copy over packages needed to a new node_modules fiolder - there is a chain of dependencies so this was not possible.
• Copying the entire node_modules folder - we have a monorepo with lots of packages so this is not really practical.
• Bundle using tsdown - this complains that there are non-JS packages which can’t be bundled.

Hey @MattyBalaam, mind setting up a minimal repro for your usecase?

That might take a while, there are a lot of moving parts, but I’ll see when I can do that.
