Current behavior

After setting up a project with CLI as described in docs (without changing code), I have tried to run a command ‘npm run start:prod’ and get this error:

> test@0.0.1 prestart:prod /home/vmois/Projects/Portal/test
> rm -rf dist && tsc

Of course the easiest solution is to install these packages, but what if I don’t use them and don’t want to install. Thanks.

Expected behavior

Compile and server in dist/main.js

Minimal reproduction of the problem with instructions

Try to setup up project with CLI, and then run ‘npm run start:prod’

If you happen to build your project in a Docker container and then run it in a different one for use in production, then don’t use npm run start:prod because it counter-intuitively deletes you dist directory.

It must have been an idea for an April fools’ day prank. 🤔

Just call node dist/main.js directly.

Just for someone else experimenting this issue, my workaround was to modify the path of main.js :

sed -i.bak 's|dist/main.js|dist/src/main.js|g' package.json
