Difference between devDependencies and Dependencies.

The difference between these two, is that devDependencies are modules which are only required during development, while dependencies are modules which are also required at runtime.
To save a dependency as a devDependency on installation we need to do an npm install --save-dev, instead of just an npm install --save.

If package is installed in optional dependency it will not produce error while npm install your project on other system and also it will not block your installation if anyone of the package didn't install properly.no save doesn't add your package to package.json
