Is it advisable to use npm devDependencies in a production environment?

While reviewing the package.json file for one of our products at work, I noticed that the SDK uses socket.io for a crucial function even though socket.io-client is listed as a devDependency. Despite this discrepancy, the SDK works flawlessly for our clients. This raises the question of why the SDK functions properly when according to documentation, devDependencies should not be installed with npm install.

Answer №1

After some investigation, I uncovered the reason behind this issue. Whenever you run npm install, npm will automatically install all dependencies, including devDependencies and regular dependencies. If you wish to exclude devDependencies from being installed, simply add the --production flag when running npm install.
