  • Как установить Node.js на Windows: пошаговая инструкция

На JavaScript выполняется большая часть интерактивных элементов на сайтах и в мобильных приложениях. JavaScript отлично работает с HTML/CSS и интегрирован основные браузеры на рынке. Чистый JavaScript используется в вебе, а для общего применения JavaScript разработчики используют различные среды выполнения, например, Node.js.

Node.js — это среда выполнения кода JavaScript. Она позволяет использовать JavaScript как язык программирования общего назначения: создавать на нем серверную часть и писать полноценные десктопные приложения.

Основа Node.js — движок V8. Этот движок был разработан Google и используется в браузере Google Chrome. Он компилирует код JavaScript в машинный код, который понимает процессор. Однако, чтобы сделать из JavaScript язык общего назначения, одного движка недостаточно. Так, например, для создания серверной части нужно, чтобы язык умел работать с файлами, сетью и т.п. Для решения этой проблемы разработчики добавили к V8 дополнительные возможности, с помощью своего кода и сторонних библиотек. В итоге у них получился инструмент, который превращает JavaScript в язык общего назначения.

Node.js стала популярна среди разработчиков благодаря возможности создавать серверную и клиентскую часть на одном языке, скорости работы и NPM. В этом материале мы расскажем, как правильно установить Node.js на Windows 10.

Удаление старых версий 

Перед установкой необходимо удалить старые версии среды выполнения, если они были ранее установлены. Наличие предыдущих версий может привести к возникновению конфликтов.

Проверим систему на наличие версий Node.js. Для этого в cmd (чтобы ее запустить, нажмите Win+R, введите cmd и нажмите Enter) выполняем команду nvm list:

C:UsersTimeweb>nvm list
    18.9.0
    18.8.0
    16.17.0

Как видим, у нас установлено несколько версий. Удалим их:

  1.  Выполняем команду npm cache clean --force.
  2. В «Установка и удаление программ» удаляем Node.js.
  3. Перезагружаем компьютер.
  4. Удаляем следующие каталоги. Некоторые из них могут существовать, а некоторые, наоборот, отсутствовать:
    • C:Program Files (x86)Nodejs
    • C:Program FilesNodejs
    • C:Users{User}AppDataRoamingnpm
    • C:Users{User}AppDataRoamingnpm-cache
    • C:Users{User}.npmrc
    • C:Users{User}AppDataLocalTempnpm-*
  5. Возвращаемся в командную строку и выполняем nvm uninstall к каждой версии, полученной с помощью nvm list:
C:UsersTimeweb>nvm uninstall 18.9.0
Uninstalling node v18.9.0... done

C:UsersTimeweb>nvm uninstall 18.8.0
Uninstalling node v18.9.0... done

C:UsersTimeweb>nvm uninstall 16.17.0
Uninstalling node v18.9.0... done

Дополнительно проверим, что версии удалены:

C:UsersTimeweb>nvm list
No installations recognized.

C:UsersTimeweb>where node
ИНФОРМАЦИЯ: не удается найти файлы по заданным шаблонам.

C:UsersTimeweb>where npm
ИНФОРМАЦИЯ: не удается найти файлы по заданным шаблонам.

С помощью nvm-windows

Node Version Manager или сокращенно NVM — это диспетчер версий Node.js. Возможно, во время работы вам придется использовать различные версии Node и переключаться между ними. Версии часто меняются, поэтому при работе рекомендуется использовать диспетчер версий.

NVM — самый распространенный диспетчер версий, но, к сожалению, в Windows он не доступен, и вместо него используется адаптированный вариант nvm-windows. 

  1. Зайдите в репозиторий nvm-windows на github.
  2. Загрузите установщик nvm-setup.exe последней версии диспетчера.
  3. После загрузки осуществите установку.
  4. По окончании работы установщика откройте PowerShell от имени администратора и проверьте работоспособность NVM:
PS C:Windowssystem32 > nvm list
No installations recognized.

Теперь нужно выбрать версию Node.js, которую вы будете устанавливать на свой компьютер. Команда nvm list available покажет частичный список доступных для загрузки версий:

Image4

Если для вашего проекта не требуется определенная версия, то рекомендуется выбрать последний LTS-выпуск. Риск возникновения проблем при работе с такой версией минимален. Если же вы хотите протестировать нововведения и улучшенные возможности, то вы можете загрузить последнюю версию. При этом не стоит забывать, что риск возникновения проблем с новейшей версией выше.

Установим последний LTS. Возьмем номер версии из результата nvm list available и установим его с помощью nvm install:

PS C:Windowssystem32> nvm install 16.17.0
Downloading node.js version 16.17.0 (64-bit)...
Extracting...
Complete
Creating C:UsersTimewebAppDataRoamingnvmtemp

Downloading npm version 8.15.0… Complete
Installing npm v8.15.0…

Installation complete. If you want to use this version, type

nvm use 16.17.0

Установка завершена. В ряде случаев при установке nvm-windows может возникнуть проблема: nvm не загрузит диспетчер пакетов NPM. В этом случае рекомендуем воспользоваться следующим способом установки.

Как установить node.js с помощью официального установщика

  1. Зайдите на официальный сайт nodejs.org в раздел «Загрузка».
  2. Выберите и загрузите нужную версию.
  3. По завершению загрузки откройте файл, после чего начнется установка.
  4. Следуйте инструкциям установщика.

Установка node.js в WSL2

Если вы хотите использовать Node.js вместе с Docker, планируете работать с командной строке Bash или просто любите Linux, то имеет смысл задуматься об установке среды выполнения в WSL2. 

WSL (Windows Subsystem for Linux) — это программная прослойка для запуска приложений, созданных под Linux-системы, на ОС Windows. Возможно, вам уже приходилось работать в WSL с приложениями, у которых нет Windows-версий. Ранее мы уже рассматривали установку Node.js на Ubuntu 20.04. Поэтому в этом разделе будет размещена инструкция по установке WSL 2 — об установке Node.js на Ubuntu читайте в статье «Как установить Node.js в Ubuntu 20.04»

Алгоритм установки WSL2 в Windows 10 зависит от версии операционной системы. Чтобы её узнать, нажмите Win+R и введите winver. После этого откроется такое окно: 

Image3

Алгоритм для версий старше 2004

В PowerShell от имени администратора выполняем следующие команды:

wsl --install 
wsl --set-version Ubuntu 2

Для проверки результата воспользуемся командой wsl.exe -l -v:

PS C:WINDOWSsystem32> wsl.exe -l -v
  NAME      STATE           VERSION
* Ubuntu    Stopped         2

Алгоритм для версий младше 2004 (как минимум потребуется ОС версии 1903)

В PowerShell (от имени администратора) активируем подсистему Windows для Linux.

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

Затем активируем функцию виртуальной машины:

dism.exe /online /enable-feature /featurename: VirtualMachinePlatform /all /norestart 

После выполнения этих действий нужно перезагрузить компьютер.

Когда компьютера запустится, скачиваем и устанавливаем пакет обновлений ядра Linux. Загрузить его можно по здесь.

В PowerShell выберем 2 версию WSL в качестве основной:

wsl --set-default-version 2

Теперь скачаем какую-нибудь операционную систему на Linux. Сделать это можно прямо магазине приложений Microsoft Store:

Заключение

Node.js — это популярная среда разработки, которая используется множеством крупных компаний: PayPal, Yahoo, Ebay, General Electric, Microsoft и Uber. В рамках этого материала мы рассмотрели способы как установить Node.js на Windows 10. 

Node.js came as a blessing for JavaScript developers worldwide struggling with swapping among multiple languages and frameworks to amplify their code into a sustainable development environment.

With Node.js, you can finally build web applications with two-way connections where both the server-side and client-side can thoroughly communicate in real-time and exchange data. Indeed, Node.js has been revolutionary for developers who wanted to push real-time web applications over WebSocket.

If you’re aiming forward to enhancing your web development skills to the next level and becoming a full-stack JavaScript developer, Node.js indeed prepares the path towards that enthusiastic buzzword!

In this article, we’ll demonstrate a step-by-step guideline for installing Node.js on your computer and commencing with your web development journey.

What Is Node.js?

Nodejs official logo.

The first thing you should know is that Node.js is not a programming language!

You may already be aware of this fact, but it bears repeating for new developers in the field who may mistake Node.js for a unique programming language. It’s not!

Node.js is an open-source runtime environment for the JavaScript language that reshapes JavaScript’s characteristics and upgrades its functionality. As a result, you can use JavaScript for frontend and backend development, enabling full-stack development solely using JavaScript.

Initially, Node.js was designed to serve real-time performance, pushed-back architectures. But since then, Node.js has grown into a vital element for server-side programming for event-driven, non-blocking servers. Most conventional websites and API services today depend on Node.js.

Before Node.js, if you wanted to store any data on the database or connect your program to the database, you needed support from a server-side language. That’s because JavaScript couldn’t regulate the backend process. Consequently, you had to learn server-side languages like PHP, Python, Ruby, or C# — or seek a backend developer’s help.

The Node.js environment empowers JavaScript to directly employ the database and function properly as a backend language. As a result, you can ultimately build and run a program using only JavaScript with Node.js.

Node.js uses the V8 JavaScript runtime engine as its root power, and it employs a non-blocking I/O architecture that’s event-driven. All these together construct Node.js and help drive products towards robust performance.

Who Uses Node.js?

According to W3Techs, to date, 1.4% of all websites use Node.js — that’s more than 22 million websites. These numbers give you a general idea of the amount of Node.js users. On top of that, Node.js has been downloaded more than 1.3 billion times! As you can see, the stats speak strongly to Node.js’ market scale.

From your friends in IT to the industry tycoons, all are enjoying leveraging Node.js. That’s because Node.js amplifies the performance of developers and increases the speed of the development process. One of the most intelligent trends nowadays is using JavaScript everywhere, which has brought Node.js into the arena.

Top companies that use Node.js include:

  1. NASA
  2. Twitter
  3. Netflix
  4. LinkedIn
  5. PayPal
  6. Trello
  7. eBay
  8. Walmart
  9. Mozilla
  10. Medium

If you study these companies, you may notice that they run their businesses on different services or products. But they all have a critical factor in common: they rely on Node.js. Indeed, using Node.js can solve most of your development issues, never mind what industry you’re in.

Advantages of Using Node.js

Choosing the right programming platform for your tech stack is as important as the labor you want to invest in. Multiple factors should be considered when you look for the advantages of using a particular platform. Things like the learning curve, development speed, community, and scale can alter the overall balance of benefits.

Here are the main advantages of using Node.js:

  • Simple syntax
  • Easy learning curve
  • Ability to scale quickly
  • Open source and flexible
  • Cross-platform development
  • Single-language full-stack development
  • Real-time communication
  • Vast and active community

Node.js Prerequisites

Before installing Node.js, you need to ensure that you’ve gathered all the necessary bits of knowledge and downloaded all required installation files and elements.

Firstly, it would help if you had a basic understanding of JavaScript and its syntax — this will make picking up Node.js easier for you.

Secondly, a basic understanding of an object-oriented programming (OOP) language will help you work on server-side coding.

Lastly, rather than rushing into deep learning, take it one step at a time. Always remember that you’re not a day late or a dollar short as long as you’re progressing.

System Requirements

Node.js doesn’t require a fancy hardware setup to run; most computers of this era should handle Node.js efficiently. Even the most miniature computers like BeagleBone or Arduino YÚN can run Node.js.

Nevertheless, much still depends on what other memory hog software you’ve got running on the same system. But in most cases, you shouldn’t be worried unless your computer is from the Mesozoic Era!

LTS Version vs Current Version

Node.js offers two different versions for you to download: the LTS version and the Current version.

The first one is Long-Term Support (LTS), which indicates the version that has been in the market for a while and comes with all mandatory support. Consequently, you can access a bunch of information and community for additional help with this version.

This LTS version is recommended to most users because of its sustainability and 18-month-long support cycle. As it’s a stable version, using it to produce backends can help you achieve a robust outcome.

The Current version indicates the latest released version of Node with the most recently added and updated features. But this version has less support behind it (around eight months) and possible bug exposure. Therefore, experts suggest using this version only for frontend development.

Considering all these factors, if you’re a regular user who loves to live hassle-free, go for the LTS version. On the other hand, if you’re an advanced user who loves the adventure of experiencing new technology, you can choose to install the Current version.

How to Install Node.js and npm

Every operating system has a distinct method of installing Node.js. The core setup file differs for each OS to OS. However, the Node.js creators have taken care to provide you with the files needed for each system.

In the next portion of the article, we’ll discuss installing Node.js on Windows, macOS, and Linux operating systems.

How to Install Node.js on Windows?

Follow this step-by-step guide to install Node.js on Windows.

1. Download Windows Installer

First, you need to download the Windows Installer (.msi) file from the official Node.js website. This MSI installer database carries a collection of installer files essential to install, update, or modify the existing Node.js version.

Notably, the installer also carries the Node.js package manager (npm) within it. It means you don’t need to install the npm separately.

When downloading, select the correct version as per your operating system. For example, if you’re using a 64-bit operating system, download the 64-bit version, and if you’re using the 32-bit version, download the 32-bit version:

How To Install Node.js on Linux?

The Linux operating system works a bit differently than the other traditional operating systems. That’s because Linux is open-source, offering you more freedom, customization, and advanced functionalities.

If you’re casual with commands, you should feel comfortable with Linux. Here, we are about to discuss the easiest method of installing Node.js on the Linux operating system.

1. Choose the Node.js Version for Your Linux Distribution

The Linux operating system has hundreds of different distributions because of the diversity it provides. And users love to customize and harness different versions’ specific functionalities using distinct distributions.

Firstly, find the installation instruction for your specific distribution from Node.js’s Binary Distributions page. For this guide, we’ll be using Ubuntu for illustration purposes.

Node.js Ubuntu installation instructions.

Node.js Ubuntu installation instructions.

2. Install the Curl Command-Line Tool

Before going for Node.js installation, ensure that you have the curl command-line utility installed on your system. If not, then paste this command on your terminal to install curl:

sudo apt install curl

It may ask for your system password to verify the permission of the installation. Once you input the password, the system should begin the curl installation.

Install "curl" on Ubuntu.

Installing “curl” on Ubuntu.

3. Start Node.js Installation

You need to copy and paste the Node.js installation command into your terminal (in our case, we can grab it from the Ubuntu distribution page) so that the system can begin the Node.js installation.

For instance, here, we’ll be installing Node.js v14.x. These are the installation commands for Ubuntu:

curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs

As you already have the curl command line installed on your terminal, you’ll need to copy and paste the first command (the curl command) on your terminal and run it.

If you’ve done everything correctly, Node.js will install correctly on your Linux distribution. Now input the Clear command to clear the terminal.

4. Verify Node.js Installation on Linux Ubuntu distribution

As you’ve installed Node.js, you can verify to check whether the installation is successful or not. To confirm the installation, you need to run two simple Linux commands on your Linux terminal.

To check the Node.js version, type:

Node --version

And to check the npm version, type:

npm --version

Verifying Node.js installation on Ubuntu.

Verifying Node.js installation on Ubuntu.

If the Node.js version and npm are installed correctly, you’ll see the Node.js and npm version names visible on the Linux terminal. It indicates that you have successfully installed Node.js and npm on your Linux distribution.

Check and Update npm Version

As we’ve mentioned, npm is the Node.js package manager. It manages the dependencies for packages. Without npm, you would have to unpack all your Node.js packages manually every time you want to upload a framework. But npm relieves you of this responsibility and takes care of it automatically.

Regularly updating npm also updates your local packages and improves the code used in your projects. However, as npm automatically installs with the Node.js version you choose, it often misses the latest npm release. In such cases, you can check your npm version and update it manually in a simple process.

The processes to check and update your npm version are very similar between Windows, macOS, and Linux — you’ll be running the same command on each.

Update npm in Windows

To check the npm version, run the following command:

npm -v

…or:

npm --version

And to update the npm version, run this command:

npm install -g [email protected]

After running this command on your CMD prompt on Windows, the system will update your npm version and install the additional packages in a few seconds. In the end, you can recheck the version to confirm the update of the npm version.

JavaScript is quickly becoming the go-to language for web developers. Front-end web developers use JavaScript to add user interface enhancements, add interactivity, and talk to back-end web services using AJAX. Web developers who work on the server-side are also flocking to JavaScript because of the efficiencies and speed offered by JavaScript’s event-driven, non-blocking nature.

In fact, concentrating on JavaScript as your language of choice offers the opportunity to master a single language while still being able to develop “full-stack” web applications.

In a previous article, I wrote about how to install Node.js® and, it’s companion, NPM on a Mac. Fortunately, for Windows users, the Node.js® installation process is a lot easier than how I recommend installing Node.js® on a Mac.

What is the Difference Between Node & NPM?

The key to this server-side JavaScript revolution is Node.js® — a version of Chrome’s V8 JavaScript runtime engine — which makes it possible to run JavaScript on the server-side.

Node.js is also used for developing desktop applications and for deploying tools that make developing web sites simpler. For example, by installing Node.js® on your desktop machine, you can quickly convert CoffeeScript to JavaScript, SASS to CSS, and shrink the size of your HTML, JavaScript and graphic files. Using NPM — a tool that makes installing and managing Node modules — it’s quite easy to add many useful tools to your web development toolkit.

When to use Node

Node isn’t a program that you simply launch like Word or Photoshop: you won’t find it pinned to the taskbar or in your list of Apps. To use Node you must type command-line instructions, so you need to be comfortable with (or at least know how to start) a command-line tool like the Windows Command Prompt, PowerShell, Cygwin, or the Git shell (which is installed along with Github for Windows).

Are you ready to start learning?

Installation Steps

Installing Node and NPM is pretty straightforward using the installer package available from the Node.js® web site.

  1. Download the Windows installer from the Nodes.js® web site.
  2. Run the installer (the .msi file you downloaded in the previous step.)
  3. Follow the prompts in the installer (Accept the license agreement, click the NEXT button a bunch of times and accept the default installation settings).
    installer
  4. Restart your computer. You won’t be able to run Node.js® until you restart your computer.

Checking if Node & NPM are Installed

Make sure you have Node and NPM installed by running simple commands to see what version of each is installed and to run a simple test program:

  • Test Node. To see if Node is installed, open the Windows Command Prompt, Powershell or a similar command line tool, and type node -v. This should print a version number, so you’ll see something like this v0.10.35.
  • Test NPM. To see if NPM is installed, type npm -v in Terminal. This should print NPM’s version number so you’ll see something like this 1.4.28
  • Create a test file and run it. A simple way to test that node.js works is to create a JavaScript file: name it hello.js, and just add the code console.log('Node is installed!');. To run the code simply open your command line program, navigate to the folder where you save the file and type node hello.js. This will start Node and run the code in the hello.js file. You should see the output Node is installed!.

Check and Update Your Node and NPM Versions

New versions of Node and NPM come out frequently. To install the updates, just download the installer from the Nodejs.org site and run it again. The new version of Node and NPM will replace the older versions.

How to Uninstall Node and NPM

You uninstall Node.js and NPM the same as you would most Windows software:

  1. Open the Windows Control Panel
  2. Choose the “Programs and Features” option
  3. Click the “Uninstall a program” option
  4. Select Node.js, and click the Uninstall link.

With Node.js and NPM installed you’ll soon be able to take advantage of the huge world of NPM modules that can help with a wide variety of tasks both on the web server and on your desktop (or laptop) machine. The NPM site lists all of the official Node packages making it easy to make the choice. Have fun!
