Below is a guide tailored to the most commonly used Node.js version managers: NVM, asdf, and nvm-windows.

Using NVM (Node Version Manager)

  • Searching for Available Versions:
    To find out which Node.js versions are available for installation, use the command nvm ls-remote. This will display a list of all Node.js versions that you can install.
  • Installing Specific Versions:
    Once you’ve identified the version you need, install it using nvm install <version>. For example, to install Node.js version 14.17.0, you would use nvm install 14.17.0.
  • Listing Installed Versions:
    To see which versions you have installed on your system, use nvm ls. This command shows all installed Node.js versions and indicates the currently active version.
  • Switching Between Versions:
    To switch to a different installed Node.js version, use nvm use <version>. If you want to switch to version 12.18.3, the command is nvm use 12.18.3.
  • Setting the Default Node.js Version: To set a version as the default for any new terminal sessions, use nvm alias default <version>. For instance, nvm alias default 14.17.0 will make Node.js 14.17.0 the default version.

Using asdf

  • Searching for Available Versions:
    With asdf, you can list all available Node.js versions by first adding the Node.js plugin with asdf plugin-add nodejs, then running asdf list-all nodejs.
  • Installing Specific Versions:
    Install a specific Node.js version with asdf install nodejs <version>. For example, asdf install nodejs 14.17.0 will install that specific version.
  • Listing Installed Versions:
    To check which Node.js versions you’ve installed, use asdf list nodejs. This command displays all Node.js versions installed through asdf.
  • Switching Between Versions:
    Switch to a different Node.js version with asdf global nodejs <version> for setting it globally, or asdf local nodejs <version> for setting it locally within a project directory.
  • Setting the Default Node.js Version:
    The asdf global nodejs <version> command sets the specified Node.js version as the default for your entire system.

Using nvm-windows

  • Searching for Available Versions:
    nvm-windows allows you to view available Node.js versions with nvm list available. This shows a list of versions you can install.
  • Installing Specific Versions: To install a specific version, use nvm install <version>. For instance, nvm install 14.17.0 will install that version on your Windows system.
  • Listing Installed Versions:
    You can list all installed Node.js versions by running nvm list. This also highlights the currently active version.
  • Switching Between Versions:
    Change the active Node.js version with nvm use <version>. For example, nvm use 12.18.3 will switch to that version.
  • Setting the Default Node.js Version: Use nvm alias default <version> to set a default Node.js version. This makes the specified version the default for new terminal sessions.

Handling Project-Specific Node.js Versions

When working on Node.js projects, it’s crucial to ensure that all developers use the same Node.js version to maintain consistency across development, testing, and production environments. Tools like .nvmrc files play a significant role in specifying project-specific Node.js versions. Here’s how you can manage and automate the use of Node.js versions on a per-project basis.

Using .nvmrc Files with NVM

  • Creating a .nvmrc File: Within your project directory, create a .nvmrc file that contains the Node.js version number your project requires. For instance, if your project needs Node.js version 14.17.0, simply write 14.17.0 in the .nvmrc file.
  • Automating Version Switching: Encourage developers to run nvm use in the terminal from the project’s root directory before starting work. NVM will automatically read the .nvmrc file and switch to the specified Node.js version. If the version isn’t installed, NVM will prompt the developer to install it.
  • Ensuring Consistency:
    Committing the .nvmrc file to your project’s version control system ensures that every developer working on the project uses the correct Node.js version, thus maintaining consistency across different machines and environments.

Integrating asdf with Project-Specific Configurations

  • .tool-versions File:
    For projects using asdf, a .tool-versions file serves a similar purpose. This file should be located in the root of your project directory and specify the Node.js version required, like nodejs 14.17.0.
  • Automatic Version Switching: When a developer navigates to the project directory in their terminal, asdf will automatically switch to the Node.js version specified in the .tool-versions file, provided they’ve installed the specified version beforehand.
  • Project Consistency:
    Including the .tool-versions file in your version control system ensures that all developers and the production environment use the same Node.js version, aligning development and deployment environments.

Best Practices for Project-Specific Node.js Versions

  • Documentation:
    Clearly document the process for switching Node.js versions in your project’s README or contributing guidelines. This helps new developers get up to speed quickly.
  • Automation Scripts:
    Consider adding shell scripts or package.json scripts that run nvm use or the asdf equivalent automatically when developers start the project. For instance, a prestart script in package.json can ensure the correct Node.js version is used before the application starts.
  • Continuous Integration (CI) Configurations:
    Ensure your CI/CD pipelines are configured to use the correct Node.js version by leveraging the .nvmrc or .tool-versions file. This consistency is crucial for avoiding “works on my machine” issues.

Advanced Configurations and Plugins

After setting up a Node.js version manager and ensuring all developers on your team can work with project-specific Node.js versions, you might want to explore more advanced features and customizations. These can include setting up aliases for different Node.js versions, managing versions of other programming languages, or handling global Node.js packages more efficiently. Let’s delve into these advanced configurations and the use of plugins for NVM, asdf, and nvm-windows.

Advanced Features in NVM

  • Aliases:
    NVM allows you to create aliases for specific Node.js versions, making it easier to switch between them. For example, you can alias a Node.js version as default, stable, or lts for easy reference. Use nvm alias <name> <version> to set an alias.
  • Default Global Packages: To automatically install certain npm packages whenever you install a new Node.js version, you can create a .nvm/default-packages file in your home directory. List each package you want installed by default on new lines within this file.

asdf Advanced Configurations and Plugins

  • Version Management for Other Languages:
    One of the most powerful features of asdf is its ability to manage versions for a multitude of languages and tools. This is done through plugins. You can find a plugin for almost any language or tool by searching the asdf plugins list or the plugin repository on GitHub.
  • Global Packages Management: While asdf does not directly manage global packages for Node.js, you can use the asdf-nodejs plugin to manage Node.js versions and then utilize npm or yarn to handle global packages. For managing packages across Node.js versions, consider using a version manager specifically for npm packages like n or npm.
  • Customizing Configurations:
    Customize your asdf setup by editing the .tool-versions file for project-specific versions or setting global versions. You can also use environment variables to alter asdf’s behavior, such as ASDF_DATA_DIR to change where asdf stores its data.

nvm-windows Advanced Features

  • Aliases and Customization:
    nvm-windows allows you to alias versions for quick switching, similar to NVM. Use nvm alias <name> <version> to create an alias. While nvm-windows focuses on Node.js, its ease of use for Windows users makes managing Node.js versions straightforward.
  • Handling Global npm Packages:
    When switching between Node.js versions with nvm-windows, your global npm packages are not automatically transferred. You’ll need to reinstall global packages or use a script to automate this process when switching versions.

Best Practices for Advanced Configuration

  • Automate Repetitive Tasks:
    Whether it’s through shell scripts, npm scripts, or aliases, automate as much of the version switching and package management process as possible to reduce manual effort and minimize errors.
  • Keep Your Configuration Files Versioned:
    Store your .nvmrc, .tool-versions, or any scripts you use for automation in version control. This ensures that new team members can set up their development environment quickly and in alignment with the team’s configurations.
  • Stay Updated:
    Version managers and plugins are regularly updated to support new versions and features. Regularly check for and apply updates to your chosen tools to take advantage of improvements and bug fixes.
