Lesser known npm commands

We all know and use npm start, npm audit, npm init and many more npm commands on a daily basis, but there are quite a few of them that are underutilized ! This article is here to show you some awesome things you can do with the npm CLI.

npm pack

Create a tarball from a package

If you’re developing an npm package and want to test if it installs without publishing, running npm pack will package your module into a tgz file that can be installed using npm install.

npm completion

Tab Completion for npm

Running npm completion will display a bash script that will take care of auto-completion of any future npm command. All you have to do is follow the instructions given by the command.
In my case, npm completion >> ~/.bashrc was enough for me to take advantage of that feature !

And that’s enough for one day !

Some of these commands are really, really useful in my opinion so I hope you’ve enjoyed this article.
If you did, following me on Twitter @christo_kade is probably the best way of showing your support. I post a lot about some cool open-source things I find, JS & CSS tricks and much more.

Thank you for reading !
