NestJs Errors stemming from @types dependencies in node_modules when running start:prod on fresh project

Question

My aim is to run a nestjs app that serves up an Angular front end. I've got an Angular cli scaffolded app at the root of the project (built using the @angular/cli latest v8 beta). Inside this folder I used the nestjs cli to scaffold a new nestjs app (app name is server).

I then cd into server and run npm run start:prod and get the following errors:

I'm using bash (windows linux subsystem) with node version 12. I have not touched anything, both apps are freshly created from the CLI.

npm run start works fine btw.

When I create a separate project on its own the nestjs app works fine, only when it is located inside a root containing an angular app do things go wrong. Could the tsconfig files be loking at the parent directory and causing issues?

Answer 1

So I was correct in thinking typescript was looking for typings across parent directories (all the way to "/" apparently).

I fixed this by adding the following command to the compilerOptions section of the tsconfig in my nestjs app:

"typeRoots": ["./node_modules/@types"],

Telling it to only look for typings in that directory.
