npm (Node Package Manager)

npm versioning (package.json version)

Examples:

"version": "1.8.8"

"version": "2.0.0-alpha.0"

"version": "2.0.0-beta.0"

The "//" key will never be used by npm for any purpose, and is reserved for comments.

If you want to use a multiple line comment, you can use either an array, or multiple "//" keys.

{

"//": "this is the first line of a comment",

"//": "this is the second line of the comment"

}

{

"//": [

"first line",

"second line"

]

}

The --save flag adds it to the package.json file.

a) Install dependencies from package.json

npm install

b) Installs a package, eg 'uuid'.

npm install --save uuid
