How do you reinstall an app's dependencies using npm?

Question

Is there a simple way to reinstall all packages that my app depends on (i.e. they are in my apps node_modules folder)?

Answer 1

Most of the time I use the following command to achieve a complete reinstall of all the node modules (be sure you are in the project folder).

rm -rf node_modules && npm install

You can also run npm cache clean after removing the node_modules folder to be sure there aren't any cached dependencies.
