Hello everyone, recently I try to make small docker image that can run in production.
I make multi stage build in my Dockerfile and have this result:

REPOSITORY                    TAG            IMAGE ID       CREATED          SIZE

nestjs-mikro-orm-dev is just images with devDependencies installed on the image, while nestjs-mikro-orm-production using npm install --only=production to install the package.

question: to have about >= 200mb image size for production is normal thing?
thank you.

Depending on the number of dependencies your application needs, I'd say that's about a normal size for a mod sized Nest app
