What is npm? | Node.js
npm is two things: first and foremost, it is an online repository for the publishing of open-source projects; second, it is a command-line utility for interacting with said repository that aids in package installation, version management, and dependency management. A plethora of libraries and applications are published on npm, and many more are added every day. These applications can be searched for on. Once you have a package you want to install, it can be installed with a single command-line command.
Let’s say you’re hard at work one day, developing the Next Great Application. You come across a problem, and you decide that it’s time to use that cool library you keep hearing about – let’s use Caolan McMahon’s async as an example. Thankfully, npm is very simple to use: you only have to run npm install async, and the specified module will be installed in the current directory under. /node_modules/. Once installed to your node_modules folder, you’ll be able to use require() on them just like they were built-ins.
Let’s look at an example of a global install – let’s say coffee-script. The npm command is simple: npm install coffee-script -g. This will typically install the program and put a symlink to it in /usr/local/bin/. This will then allow you to run the program from the console just like any other CLI tool. In this case, running coffee will now allow you to use the coffee-script REPL.
Another important use for npm is dependency management. When you have a node project with a file, you can run npm install from the project root and npm will install all the dependencies listed in the This makes installing a project from a git repo much easier! For example, vows, a testing framework, can be installed from git, and its single dependency, eyes, can be automatically handled:
git clone cd vows
After running those commands, you will see a node_modules folder containing all of the project dependencies specified in the

Hosting private NPM packages for free

If you want to host a private NPM package but do not want to pay US$ 7 per user, per month to host it directly at this post is for you. Here I will share a very practical way you can host it privately for free at Github Packages Registry + NPM.
Important: The instructions presented here are valid as long as Github provides a free plan for private repositories.
Publishing the package
Get your Github Token
The first thing you need to do is to generate a Github token with the following scopes allowed:
read:packages, write:packages, and delete:packages
Here you can find details on how to create the Github Token:
Authenticate your local NPM into Github Packages Registry
Now you need to configure your npmrc file to use the Github Package registry for your private repositories.
This is how your npmrc local file must look like:
The first line is the default NPM package registry, from where you will still be downloading public packages.
The second line tells NPM to get packages from the organization @energicos from the Github Registry instead of the default NPM Registry. This way when we create a package with a name such as @energicos/entities, NPM will download it from which is the Github Packages Registry URL.
The third line is for authentication purposes. Here you should change the your_token with the Github Token you have generated with the proper scopes.
Update the file
Now you must include at the file of you NPM package, the Github Package URL:
Finally, having it all done, now you can just publish the NPM package privately and for free by running:
Any client properly authenticated into the Github Packages Registry can install the package by running:
npm install @energicos/baseapp
Checking the published package
Through the Github UI, we can see all the published packages, versions, descriptions, and we can also download its content.
To list all the published packages:
That’s it! Now you can have private and free NPM packages easily published.
