npm.txt

npm is a package manager. it's a website that keeps a big catalog of software
that can be installed by anyone.

some of that software you use directly, but other software you use as parts.

software you use directly:

  "bin"

software you use as a dependency:

  "main"

--------------------------------------------------------------------------------

npm works really well with GitHub, but isn't dependent on GitHub. when you
publish a module to npm

  $ npm publish

you upload a copy of that software to npmjs.org. When people install your module
with npm

  $ npm install that-module

they are downloading it from npmjs.org

--------------------------------------------------------------------------------

To install software with npm, you use the `install` method. This both downloads
and installs the software. There are two ways to install software - one which
makes it easy to include as a part of your application, and another that
lets you use the software directly:

You install software as part of your application like

  $ npm install chalk --save

chalk is a module you use by including it in your program: it helps your program
color text.

And you install software to use yourself like

  $ npm install cli-weather -g

cli-weather shows you the weather: after you install it, you get a new command
line command called `weather` that tells you the weather.

--------------------------------------------------------------------------------

Let's install the weather

  $ npm install cli-weather -g

Now run

  $ weather -a "Bangalore"
