npm package version syntax code example

Example 1: npm check package version

local packages:
~$ npm list

globally installed packages:
~$ npm list -g

specific package:
~$ npm list <package>

Example 2: how to install latest version of npm package

//For global packages 
npm i -g <package name>@latest
npm i -g express@latest

//For loacal packages
npm outdated
npm update

//Manually updating local packages
npm i <package name>@latest
npm update "react" "react-dom"

Example 3: what does "*" version mean in npm package dependency

Finally there is the *, which while available, isn’t used as often. The primary reason for its less frequent use is the fact that it acts as a stand in for either the major, minor, or patch number and catches any version number for the place that it represents. For example a dependency with a version of * would equate to any version that was greater than or equal to 0.0.0, while 1.* would allow versions greater than or equal to 1.0.0 and less than 2.0.0.

Example 4: npm version notation

1.2.3 => 1.2.3 (Matching exactly same version)
~1.2.3 => >=1.2.3 && < 1.3.0 (Matching minor version)
^1.2.3 => >=1.2.3 && < 2.0.0 (Matching major version)

Example 5: npm package version

// How to increment your project version
Ex: 1.0.0

* npm version patch ---> 1.0.1
* npm version minor ---> 1.1.0
* npm version major ---> 2.0.0

npm version [<newversion> | major | minor | patch | premajor | 
preminor | prepatch | prerelease [--preid=<prerelease-id>] | from-git]

Example 6: npm package at version

npm install <package>@<version>
