Description

I spun up my new WSL VM this afternoon and discovered the npm run build script is using an insane amount of memory. I received a Node out of memory heap error and had to increase using this environment variable.

export NODE_OPTIONS=--max_old_space_size=6000

It looks like at peak build, it nearly uses 3GB of memory which is absolutely insane. It fails right at the TypeScript build.

Step-by-step reproduction instructions

1. Spin up a WSL2 Ubuntu 20.04 VM.
2. Clone the repo.
3. Run npm i && npm run build.
4. See error.
