In a previous post, I’ve talked about Homebrew (and why it’s part of my setup).
Brew 下 安装node 和 npm. 其实npm是nodejs的包管理器(package manager)。我们在Node.js上开发时,会用到很多别人已经写好的javascript代码,如果每当我们需要别人的代码时,都根据名字搜索一下,下载源码,解压,再使用,会非常麻烦。. Node from Homebrew / Chocolatey # “Homebrew — the best friend of the macOS user” explains why I love this tool so much. Windows users can find an alternative like Chocolatey. Both of these package managers allow you to install Node.js with ease. Brew install node choco install nodejs.install.
I’ve also talked about Node, Gulp, and a few starter packages that I recommend for getting started with using them in WordPress development.
But one of the things I’ve not talked about is how to install Node using Homebrew.
Using Homebrew to Install Node
There are some ways to install packages on a Mac. Depending on the application, you can use the Mac App Store; you can use Composer, you can download something directly from a repository like GitHub, and so on.
But using a package manager comes with several benefits:
- it finds, downloads, and installs the package for you,
- it makes updating the software very easy,
- it makes uninstalling packages easy, too.
If you’re into a little bit of self-inflicted pain, then you can forgo any of the above. ☺️
But if you’re looking to save a little bit of time so you can focus on work, then I highly recommend Homebrew (or another package manager depending on the type of work you’re doing).
Installing Node with Homebrew
With all of the above said, this is why I’m a fan of using Homebrew to install Node and then, in turn, using Node to install packages such as Gulp.
First, make sure everything is good to go on your system, run the following commands:
You may need to run any commands that doctor provides; otherwise, simply run update, and you’re good to go.
To install Node using Homebrew, open your terminal and enter the following command:
After that, installing Gulp is easy.
Installing Gulp with Node
While still in your terminal, use the following command:
This is often the easiest step, but it can be confusing especially if you’re new to package management.
Essentially, you’ve used one package manager, Homebrew, to install another package manager, Node. The easiest way to think about it is to think of Homebrew as responsible for installing executable binaries and Node as installing JavaScript executables (or related libraries).
But, with that, this is yet another way to continue making sure your setup is as reliable as it can be while still being able to focus on work.
-->If you are using Node.js professionally, find performance speed and system call compatibility important, want to run Docker containers that leverage Linux workspaces and avoid having to maintain both Linux and Windows build scripts, or just prefer using a Bash command line, then you want to install Node.js on the Windows Subsystem for Linux (more specifically, WSL 2).
Using Windows Subsystem for Linux (WSL), enables you to install your preferred Linux distribution (Ubuntu is our default) so that you can have consistency between your development environment (where you write code) and production environment (the server where your code is deployed).
Note
If you are new to developing with Node.js and want to get up and running quickly so that you can learn, install Node.js on Windows. This recommendation also applies if you plan to use a Windows Server production environment.
Install WSL 2
WSL 2 is the most recent version available on Windows 10 and we recommend it for professional Node.js development workflows. To enable and install WSL 2, follow the steps in the WSL install documentation. These steps will include choosing a Linux distribution (for example, Ubuntu).
Once you have installed WSL 2 and a Linux distribution, open the Linux distribution (it can be found in your Windows start menu) and check the version and codename using the command: lsb_release -dc
.
We recommend updating your Linux distribution regularly, including immediately after you install, to ensure you have the most recent packages. Windows doesn't automatically handle this update. To update your distribution, use the command: sudo apt update && sudo apt upgrade
.
Install Windows Terminal (optional)
Windows Terminal is an improved command line shell that allows you to run multiple tabs so that you can quickly switch between Linux command lines, Windows Command Prompt, PowerShell, Azure CLI, or whatever you prefer to use. You can also create custom key bindings (shortcut keys for opening or closing tabs, copy+paste, etc.), use the search feature, customize your terminal with themes (color schemes, font styles and sizes, background image/blur/transparency), and more. Learn more in the Windows Terminal docs.
Node Brewers
Install Windows Terminal using the Microsoft Store: By installing via the store, updates are handled automatically.
Install nvm, node.js, and npm
Besides choosing whether to install on Windows or WSL, there are additional choices to make when installing Node.js. We recommend using a version manager as versions change very quickly. You will likely need to switch between multiple versions of Node.js based on the needs of different projects you're working on. Node Version Manager, more commonly called nvm, is the most popular way to install multiple versions of Node.js. We will walk through the steps to install nvm and then use it to install Node.js and Node Package Manager (npm). There are alternative version managers to consider as well covered in the next section.
Important
It is always recommended to remove any existing installations of Node.js or npm from your operating system before installing a version manager as the different types of installation can lead to strange and confusing conflicts. For example, the version of Node that can be installed with Ubuntu's apt-get
command is currently outdated. For help with removing previous installations, see How to remove nodejs from ubuntu.)
Open your Ubuntu 18.04 command line.
Install cURL (a tool used for downloading content from the internet in the command-line) with:
sudo apt-get install curl
Install nvm, with:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
Note
At the time of publication, NVM v0.35.3 was the most recent version available. You can check the GitHub project page for the latest release of NVM, and adjust the above command to include the newest version.Installing the newer version of NVM using cURL will replace the older one, leaving the version of Node you've used NVM to install intact. For example:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash
To verify installation, enter:
command -v nvm
...this should return 'nvm', if you receive 'command not found' or no response at all, close your current terminal, reopen it, and try again. Learn more in the nvm github repo.List which versions of Node are currently installed (should be none at this point):
nvm ls
Install the current release of Node.js (for testing the newest feature improvements, but more likely to have issues):
nvm install node
Install the latest stable LTS release of Node.js (recommended):
nvm install --lts
List what versions of Node are installed:
nvm ls
...now you should see the two versions that you just installed listed.Verify that Node.js is installed and the currently default version with:
node --version
. Then verify that you have npm as well, with:npm --version
(You can also usewhich node
orwhich npm
to see the path used for the default versions).To change the version of Node.js you would like to use for a project, create a new project directory
mkdir NodeTest
, and enter the directorycd NodeTest
, then enternvm use node
to switch to the Current version, ornvm use --lts
to switch to the LTS version. You can also use the specific number for any additional versions you've installed, likenvm use v8.2.1
. (To list all of the versions of Node.js available, use the command:nvm ls-remote
).
If you are using NVM to install Node.js and NPM, you should not need to use the SUDO command to install new packages.
Alternative version managers
Node Brewery
While nvm is currently the most popular version manager for node, there are a few alternatives to consider:
- n is a long-standing
nvm
alternative that accomplishes the same thing with slightly different commands and is installed vianpm
rather than a bash script. - fnm is a newer version manager, claiming to be much faster than
nvm
. (It also uses Azure Pipelines.) - Volta is a new version manager from the LinkedIn team that claims improved speed and cross-platform support.
- asdf-vm is a single CLI for multiple languages, like ike gvm, nvm, rbenv & pyenv (and more) all in one.
- nvs (Node Version Switcher) is a cross-platform
nvm
alternative with the ability to integrate with VS Code.
Install Visual Studio Code
We recommend using Visual Studio Code with the Remote-development extension pack for Node.js projects. This splits VS Code into a “client-server” architecture, with the client (the VS Code user interface) running on your Windows operating system and the server (your code, Git, plugins, etc) running 'remotely' on your WSL Linux distribution.
Note
This “remote” scenario is a bit different than you may be accustomed to. WSL supports an actual Linux distribution where your project code is running, separately from your Windows operating system, but still on your local machine. The Remote-WSL extension connects with your Linux subsystem as if it were a remote server, though it’s not running in the cloud… it’s still running on your local machine in the WSL environment that you enabled to run alongside Windows.
- Linux-based Intellisense and linting is supported.
- Your project will automatically build in Linux.
- You can use all your extensions running on Linux (ES Lint, NPM Intellisense, ES6 snippets, etc.).
Brew Node Version
Other code editors, like IntelliJ, Sublime Text, Brackets, etc. will also work with a WSL 2 Node.js development environment, but may not have the same sort of remote features that VS Code offers. These code editors may run into trouble accessing the WSL shared network location (wsl$Ubuntuhome) and will try to build your Linux files using Windows tools, which likely not what you want. The Remote-WSL Extension in VS Code handles this compatibility for you, with other IDEs you may need to set up an X server. Support for running GUI apps in WSL (like a code editor IDE) is coming soon.
Terminal-based text editors (vim, emacs, nano) are also helpful for making quick changes from right inside your console. The article, Emacs, Nano, or Vim: Choose your Terminal-Based Text Editor Wisely does a nice job explaining some differences and a bit about how to use each.
To install VS Code and the Remote-WSL Extension:
Download and install VS Code for Windows. VS Code is also available for Linux, but Windows Subsystem for Linux does not support GUI apps, so we need to install it on Windows. Not to worry, you'll still be able to integrate with your Linux command line and tools using the Remote - WSL Extension.
Install the Remote - WSL Extension on VS Code. This allows you to use WSL as your integrated development environment and will handle compatibility and pathing for you. Learn more.
Important
If you already have VS Code installed, you need to ensure that you have the 1.35 May release or later in order to install the Remote - WSL Extension. We do not recommend using WSL in VS Code without the Remote-WSL extension as you will lose support for auto-complete, debugging, linting, etc. Fun fact: This WSL extension is installed in $HOME/.vscode-server/extensions.
Helpful VS Code Extensions
While VS Code comes with many features for Node.js development out of the box, there are some helpful extensions to consider installing available in the Node.js Extension Pack. Install them all or pick and choose which seem the most useful to you.
To install the Node.js extension pack:
Node Brewton
Open the Extensions window (Ctrl+Shift+X) in VS Code.
The Extensions window is now divided into three sections (because you installed the Remote-WSL extension).
- 'Local - Installed': The extensions installed for use with your Windows operating system.
- 'WSL:Ubuntu-18.04-Installed': The extensions installed for use with your Ubuntu operating system (WSL).
- 'Recommended': Extensions recommended by VS Code based on the file types in your current project.
In the search box at the top of the Extensions window, enter: Node Extension Pack (or the name of whatever extension you are looking for). The extension will be installed for either your Local or WSL instances of VS Code depending on where you have the current project opened. You can tell by selecting the remote link in the bottom-left corner of your VS Code window (in green). It will either give you the option to open or close a remote connection. Install your Node.js extensions in the 'WSL:Ubuntu-18.04' environment.
A few additional extensions you may want to consider include:
Noda Brewery Menu
- Debugger for Chrome: Once you finish developing on the server side with Node.js, you'll need to develop and test the client side. This extension integrates your VS Code editor with your Chrome browser debugging service, making things a bit more efficient.
- Keymaps from other editors: These extensions can help your environment feel right at home if you're transitioning from another text editor (like Atom, Sublime, Vim, eMacs, Notepad++, etc).
- Settings Sync: Enables you to synchronize your VS Code settings across different installations using GitHub. If you work on different machines, this helps keep your environment consistent across them.
Set up Git (optional)
To set up Git for a NodeJS project on WSL, see the article Get started using Git on Windows Subsystem for Linux in the WSL documentation.
