Pinia with Nuxt3 causing large bundle size when deployed to AWS Lambda

[mferraco]

Context

I am building a Vue3/Nuxt3 project using Pinia and set up the project as defined here.

I am deploying my project to aws-lambda and I'm using vite bundler that comes packaged with Nuxt to create the project bundle that is uploaded to AWS.

Problem

When this project is deployed with @pinia/nuxt included as a dependency, the deployed project size in aws lambda is 33mb.
When this project is deployed without @pinia/nuxt included as a dependency, the deployed project in aws lambda is 9.3 mb.

This is an issue because AWS Lambda has a deployment package max size of 50mb zipped.

After digging into the files included in the deployed bundle, I realized that the @pinia/nuxt package is including typescript as a dependency in the deployed package on aws lambda. The typescript package alone results in >70% of the 33mb package size when @pinia/nuxt is included in the project. It disappears when @pinia/nuxt is removed from the project. This package is a dev dependency and shouldn't be in the deployment package.

Question

Why is typescript being included as a dependency when deploying my project with @pinia/nuxt?

TypeScript is probably brought in by @nuxt/kit somewhere down in its dependency tree.
When you deploy your application, are you packing your node_modules? I think you only need to deploy the .output folder. Although, there is a preset for AWS: https://v3.nuxtjs.org/getting-started/deployment/#deployment
