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 install Node.js on Windows Subsystem for Linux (more specifically, WSL 2).

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 Node.js versions 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, but is only available for Mac/Linux and not supported on Windows. Instead, we recommend installing nvm-windows and then using it to install Node.js and Node Package Manager (npm). There are alternative version managers to consider as well covered in the next section.
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. This includes deleting any existing Node.js installation directories (e.g., "C:\Program Files\nodejs") that might remain. NVM's generated symlink will not overwrite an existing (even empty) installation directory. For help with removing previous installations, see How to completely remove node.js from Windows.)
NVM is designed to be installed per-user, and invoked per-shell. It is not designed for shared developer boxes or build servers with multiple build agents. NVM works by using a symbolic link. Using nvm in shared scenarios creates a problem because that link points to a user's app data folder -- so if user x runs nvm use lts, the link will point node for the entire box to their app data folder. If user y runs node or npm, they will be directed to run files under x's user account and in the case of npm -g, they will be modifying x's files, which by default is not allowed. So nvm is only prescribed for one developer box. This goes for build servers too. If two build agents are on the same vm/box, they can compete and cause odd behavior in the builds.
Follow the install instructions on the windows-nvm repository. We recommend using the installer, but if you have a more advanced understanding of your needs, you may want to consider the manual installation. The installer will point you to the releases page for the most recent version.
Once the installation is complete. Open PowerShell (recommend opening with elevated Admin permissions) and try using windows-nvm to list which versions of Node are currently installed (should be none at this point): nvm ls
Install the latest stable LTS release of Node.js (recommended) by first looking up what the current LTS version number is with: nvm list available, then installing the LTS version number with: nvm install (replacing with the number, ie: nvm install 12.14.0).
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 directory cd NodeTest, then enter nvm use replacing with the version number you'd like to use (ie v10.16.3`).
To install Volta as your version manager (rather than windows-nvm), go to the Windows Installation section of their Getting Started guide, then download and run their Windows installer, following the setup instructions.
If you plan to collaborate with others, or host your project on an open-source site (like GitHub), VS Code supports version control with Git. The Source Control tab in VS Code tracks all of your changes and has common Git commands (add, commit, push, pull) built right into the UI. You first need to install Git to power the Source Control panel.
An Install Wizard is included that will ask you a series of questions about settings for your Git installation. We recommend using all of the default settings, unless you have a specific reason for changing something.
Using Node.js directly on Windows is great for learning and experimenting with what you can do. Once you are ready to build production-ready web apps, which are typically deployed to a Linux-based server, we recommend using Windows Subsystem for Linux version 2 (WSL 2) for developing Node.js web apps. Many Node.js packages and frameworks are created with a *nix environment in mind and most Node.js apps are deployed on Linux, so developing on WSL ensures consistency between your development and production environments. To set up a WSL dev environment, see Set up your Node.js development environment with WSL 2.
If you are in the (somewhat rare) situation of needing to host a Node.js app on a Windows server, the most common scenario seems to be using a reverse proxy. There are two ways to do this: 1) using iisnode or directly. We do not maintain these resources and recommend using Linux servers to host your Node.js apps.
Juliaup is a new Julia version manager for Windows that is distributed via the Windows Store and manages your Julia installation on Windows. Juliaup makes it easy to keep your Julia installation up-to-date and to manage multiple Julia versions on one system. Juliaup is currently in preview, but should be fairly stable and ready for real world usage.
Once you have that installed, julia is on the PATH, there is a start menu shortcut and it will show up as a profile in Windows Terminal. Any of those will start Julia. The VS Code extension will also automatically find this Julia installation.
The code for Juliaup and the installer is hosted at GitHub - JuliaLang/juliaup: Julia installer and version multiplexer. Most of it is written in Julia itself, so it should be fairly easy to help and contribute Which of course would be fantastic! There is a long list of improvements that would make things work smoother, we need help with the artwork for the store listing, and it would be great if some folks would try to port this to Mac and Linux!
If you do try this, please report back about your experience here! In particular if things work, before we could make this a more official option we need some confirmation that things actually work for folks.
One suggestion: I had Julia 1.6 installed before with Revise in my startup. After installing Juliaup (with Julia 1.5), Julia did not start because Revise is not in my (blank) 1.5 default environment. This is of course easy to fix, but slightly inconvenient.
Would it be possible to copy the newest / closest existing default environment if a new Julia minor version is installed?
Hm, so I think you should probably treat C:\Users\jrafa\.julia\juliaup\x64\julia-1.6.1\etc\julia\startup.jl as read-only, right? The way the VS Code extension should (in theory) find this install is that if there is a julia command on the PATH, then the extension will use that. So not sure, but maybe you have another julia on your PATH somehow? You can pretty easily figure out which version of Julia exactly is running inside the VS Code Julia REPL by typing Sys.BINDIR in the REPL.
Re the VS Code situation: my best guess is that you have a path to the Julia binary configured in VS Code, and that will stay around, even if you uninstall the VS Code extension. The way to fix this is to go into your user settings in VS Code, go to the Julia section and remove the configuration for the Julia binary path, so that that setting is just empty. At that point the extension should find the Juliaup configured Julia.
For the PATH and how Windows 10 finds the executables, juliaup uses the folder AppData\Local\Microsoft\WindowsApps\ . There you find (hard) links (I think) to the executables and this folder is in the PATH by default.
This is in my opinion, a very clean way to make julia available as easy as possible without changing anything the user may have set by purpose (like an entry in the PATH envrionment).
Yes, exactly! And that whole part is actually handled by the MSIX installer engine that ships with Windows 10, the way we hook into this is that we just declare that we want something to appear on the path in this line in the setup program.
I am trying to develop an elixir desktop app for windows. While installing a static version of Elixir can help me for a while, I often try new versions and I like to keep my projects up to date. So clearly I need several versions of Elixir as I have multiple projects.
Normally I would code in some Linux variant, install asdf and be happy with it.
However asdf does not have support for Windows. If it supports Windows then it is not documented in their official webpage.
But if you maintain a set of custom manifests with the desired versions
and if you tweak somehow which version will be abailable in path,
it could possibly be the thing that let you change the versions globally most quickly.
No. Not in my point of view.
You should be able to install multiple versions from custom scoop manifest files.
And then only, as example now, rename the desired version within the scoop shims folder.
Then in a new shell the desired version should be available,
as scoop added the shims folder to windows path.
But different approuches would probably work also.
Scoop does only symlink the latest installed versions to a current link folder.
So it does not uninstall old versions automatically, as its always only a linked potable installation.
I lost Manager in Windows 8 everything I tried did not fix it. I upgraded to Windows 10 and still never worked again this is the Desktop Version. Nothing fixed it s and I lost 14 months of my business and all my clients data as well and there is no hep at all. I finally went to Studio Cloud and it is working great. Unfortunately I had to start from scratch. I would have loved to stay with Manager as I think it is a great system but with no help no fixes and over a year of lost accounts and business data I had to go some place.
