How To Check Installed NPM Package Version in Node.js (2024)

Using NPM as a Node.js package manager comes as standard. All of our Node.js packages and modules, internal and external, are under the management of NPM. We require external packages that can be installed either locally in a certain directory on our system or globally so that they can be accessed from any location on the computer to suit the developer's needs.

The npm package may be installed locally with the following command: By running this command, we will download the package and install it in our home directory. If you want more details on check npm package version, you can take a Node.js advanced course.

What is an NPM Package?

The default package check npm package version for Node.js, NPM (Node Package Manager), is developed in JavaScript. It was launched on January 12, 2010, by Isaac Z. Schlueter, a developer. NPM is a command line client for Node.js that maintains all Node.js packages and modules. When Node.js is installed, it is automatically added to the system. NPM is used to set up the Node.js packages and modules.

NPM has two key components:

Command line tool for publishing and downloading packages, and a CLI (command-line interface) tool
A website where JavaScript packages may be found

The package.json file may be used to install all of a project's dependencies using NPM. Packages may also be updated or removed. Allowing for the automatic updating of packages while avoiding breaking changes, the semantic versioning technique may be used to establish the range of acceptable versions for each dependency.

How to Check Installed NPM Specific Package Version?

This post will go through how to check installed npm version and what its dependencies are. The latest versions of all packages have been downloaded and installed.

Checking Installed NPM Version Using the “npm show” Command

The npm show command is a handy tool for determining the version of an installed npm package. Runningnpmshow[package-name]version returns the precise version of the package installed in your project. For example, to check the version of express in your project, you would run:

npm show express version

Checking Installed NPM Version Using the Node.js console

A simple script can be executed in the Node.js console to check the version of an installed npm package. First, launch the Node.js console by typingnodein your terminal. Then, use the require function to load the package and log its version.

constexpress =require('express');console.log(express.version);

This script will output the version of the express package installed in yourproject. Replace express with the name of the packageyou'dlike to verify.

Checking NPM Version with Package.json File

Thepackage.jsonfile in your project's root directorycontainsa list of all dependencies and their versions. Openpackage.jsonand search in the dependencies ordevDependenciessections for the version of the installed packages. An example ofpackage.jsonfile can be:

"dependencies": {"express":"^4.17.1","react":"^17.0.2"}

This filecontainsa full list of all installed packages and versions, making it simple to verify and manage dependencies.

Checking NPM Version Using a Code Editor

Modern code editors, such as Visual Studio Code, include integrations for managingnpmpackages. In VS Code, you may view installed package versions directly from the integrated terminal or by going to thepackage.jsonfile, where the editorfrequentlyhighlights and gives easy access to installed packages and versions. Furthermore, several editors provide extensions that display npm package versions and changes, which simplifies dependency management.

Check Installed Version of All Packages

NPM has evolved a lot since you first started working with Node.js. Is it conceivable that you just mindlessly followed the instructions and kept adding the -g option?

New to npm? You might have used the -g flag unknowingly when installing packages, potentially littering your system with unnecessary global installations. While this flag makes tools like the Angular CLI globally accessible, it can also lead to clutter. These globally installed packages (like Angular CLI) stick around even if you remove a single project that used them.

The real challenge comes from dependencies.Each package often has its own dependencies,creating a complex web of interconnected installations.This can make managing your npm environment difficult.

To keep things organized, be mindful of the -g flag. Use npm list --global to see all globally installed packages. If you just need a clear picture of the top-level global installations (the core packages you installed directly), use npm list --global --depth=0 instead. This will help you maintain a clean and manageable development environment.

It's now easier than ever to inspect all of your installed Node.js packages. To know more you may take the best full stack developer course with placement.

Check Packages with Required Updates

In our project, many npm check updates are used. As new versions of packages are released on a regular basis, it is vital to do regular updates. Not doing so puts us at danger of using a new feature that is only available in the most current versions, or even worse, neither of those things.

To stay current, these programs need to be npm check update often. Many methods exist for determining whether or not an application has been updated.

Installing the npm check package version is the first step since it's simple to use and provides an interactive interface.

Each npm package that has been used will be included, along with any significant or small updates, patches, and links to the packages themselves.

Patches, minor, major, and non-server updates are organized by kind in the NPM checker: We have the ability to do a full patch update at this time. Next, we should go through each and every one of the modifications, both minor and major. Each dependent's website or repository URL is also provided by npm-check.

A graphical user interface (GUI) that allows the user to pick and select which modules to update is required.

Using the —user parameter on npm-check to do a check

The arrows up and down may be used to move between different libraries. If you want to update a library faster, press "space" before selecting the library you want to update. To finish the upgrade, all you have to do is hit Enter.

Your package-lock.json will be updated if you alter your dependencies.

NPM has a few facts

As of today, NPM has more than 580096 registered applications. At an average of 291/day, this figure dwarfs all other package repositories.
npm is free and open source software.
Lodash, async, react, request, and express are the top npm packages in decreasing order.

In order to get NPM up and running

Node.js must first be installed before you npm version check can be set up, since NPM is set up automatically when Node.js is.

Conclusion

Installing packages from an earlier version may cause the following problems: - You may be missing out on new features or bug fixes that are only available in the most recent releases. Your version of R may not be compatible with the earlier package that is required. Either downgrade R to a compatible version or rewrite your code so that it works with a newer package, whatever you choose. To avoid these issues, use the NPM check package version command to ensure you are using the latest version of your Node.js packages.
