On Windows, a symbolic directory link is created at %ProgramFiles%\Nodejs, and that directory is added to the system PATH. Using NVS to link a different version of node (with different global modules) updates all the links accordingly.
Windows get node js version update#
Note after installing or uninstalling global modules that include executables it may be necessary to run nvs link again to update the global links. On non-Windows platforms, symbolic links are created in /usr/local/bin for node, npm, and any globally-installed node modules that have executables. (This is only allowed if there is not already a system-installed node.) If $NVS_HOME is under a system path such as /usr/local or %ProgramFiles%, then the nvs link command additionally links into well-known Node.js system locations. The nvs ls command lists all local node versions, marks the version currently in the path with a >, and marks the default (linked) version, if any, with a #.
On Windows, the PATH environment variable is updated in the user profile, so that new shells will use the default version. On non-Windows platforms, a new shell that sources the nvs.sh script also sets PATH to include the default version, if a link is present. This can be useful when there is a need to configure a fixed path elsewhere. The nvs link command creates a symbolic directory link at $NVS_HOME/default that points to the specified version (or the current version from PATH at the time of the command). The nvs migrate command can migrate those global modules from one node version to another. (NVS clears any NPM_CONFIG_PREFIX environment variable that may have been set.) This means when NVS switches versions it is also switching the set of available global modules.

When using npm install -g or npm link with NVS-installed node, global modules are installed or linked into a version-specific directory. When you nvs use a version, the PATH of the current shell is updated to include that version's bin directory. Each build goes in a subdirectory based on the remote name, semantic version, and architecture, for example node/6.7.0/圆4. NVS downloads node builds under the directory specified by the NVS_HOME environment variable, or under the NVS tool directory if NVS_HOME is not set.

But all the code for querying available versions, downloading and installing node and matching npm, switching versions/architectures/engines, uninstalling, parsing and updating PATH, and more can be written in JavaScript, and mostly in a cross-platform way.
Besides bootstrapping, the shell scripts are also used to export PATH changes to the calling shell (which a separate node process cannot do).

The bootstrap code is just a few dozen lines each of Windows command script, Windows powershell script, and POSIX shell script. NVS uses a small amount of platform-specific shell code that bootstraps the tool by automatically downloading a private copy of node. (You may need to specify an absolute path such as "$/.nvs/nvs" if NVS is not in VS Code's PATH.)Įxample: Configure launch.json so VS Code uses NVS to launch node version 6.10: vscode located on the project's root folder), add a "runtimeArgs" attribute with an NVS version string and a "runtimeExecutable" attribute that refers to nvs.cmd (Windows) or nvs (Mac, Linux). Visual Studio Code can use NVS to select a node version to use when launching or debugging. NVS uses console-menu, a module originally written for this project then published separately. When invoked with no parameters, nvs displays an interactive menu for switching and downloading node versions. Refer to the docs for more details about each command. A version or filter consists of a complete or partial semantic version number or version label ("lts", "latest", "Argon", etc.), optionally preceded by a remote name, optionally followed by an architecture, separated by slashes.
