I've tried both --save and --save-dev npm installing, but in package.json, I only see something in dependencies rather than dev dependencies. So when do we use each of these?
- npm install something
- npm install something --save
- npm install something --save-dev

The differences between all three are as follow.
- will install the npm package to your node_modules folder and not be added to the package.json
- --save - package(s) required by the application to run
- --save-dev - package(s) required for development purpose.

19,985 PointsOk it makes sense. I was just having an error that threw me off -- my index.html wasn't being updated with --save for some reason the first time. Thank you!
