asdf
asdf is a version manager that aims to be a “universal language version manager.” Created by Jean-Louis Reynaud in 2015, it supports a wide variety of programming languages and tools, including Node.js. It is designed to be easily extendable as new languages and tools are introduced.
asdf currently supports Node.js, Ruby, Python, Elixir, Java, Rust, PHP, Perl, Haskell, R, Lua, and Erlang. For all of these languages, you can manage different versions in one place via a single .tool-versions configuration file. This file can be included in your project repository so that the entire team uses the same versions of the tools.
How to Install and Use
Dependencies required for asdf:
First, we need to install some dependencies like coreutils, curl, and git. These dependencies are used by asdf to manage different language versions.
macOS:
- Homebrew:
brew install coreutils curl git
- Spack:
spack install coreutils curl git
Linux:
sudo apt install curl git
Installationon macOS and Linux:
Installation via Git:
Open the terminal and run the following command:
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.13.1
Or install via Homebrew (only for macOS):
brew install asdf
Shell Configuration: Add the following lines to your shell configuration file (e.g., ~/.bashrc or ~/.zshrc):
- Bash/Zsh:
. $HOME/.asdf/asdf.sh
. $HOME/.asdf/completions/asdf.bash
Then apply the changes with:
source `~/.bashrc`
source `~/.zshrc`
Installation for Windows:
To install asdf on Windows, use the Windows Subsystem for Linux (WSL):
- Set up WSL: Install and set up WSL on your system using the Microsoft guide.
- Install asdf in WSL: Follow the installation instructions for asdf for Linux, as described above.
After setting up asdf in your shell configuration, plugins are installed to manage specific tools. When a tool is installed, shims (proxy files) are created, which intercept calls to executables, determine the tool version from .tool-versions, and execute the corresponding version.
Using asdf:
- List all available plugins:
asdf plugin list all - Add a plugin:
asdf plugin add nodejs - List installed plugins:
asdf plugin list - Remove a plugin:
asdf plugin remove nodejs - Update a plugin:
asdf plugin update nodejs - Update all plugins:
asdf plugin update --all - Install a specific version or starting with a certain number of Node.js:
asdf install nodejs 16.13.0orasdf install nodejs latest:18 - Install the latest available version:
asdf install nodejs latest - Set the global version (default):
asdf global nodejs 16.13.0 - Set the version for the current project:
asdf local nodejs 16.13.0 - Remove a version of Node.js:
asdf uninstall nodejs 16.13.0 - View installed versions of Node.js:
asdf list nodejs - View all available Node.js versions:
asdf list all nodejs - Install versions from the
.tool-versionsfile:asdf install - Show the current active version of Node.js:
asdf current nodejs
.tool-versions Configuration File:
- What it is:
.tool-versionsis a text file in the project's root directory that defines the versions of all tools used in the project. - Why it’s needed: Ensures that all team members use the same tool versions, simplifies environment setup, and prevents version conflicts.
Example content of the **.tool-versions** file:
nodejs 16.13.0
Advantages of asdf:
- Versatility: Manage versions of various languages and tools with a single manager (one CLI).
- Uniform commands: Using the same commands for all tools simplifies work and reduces the need to learn different commands.
- Single configuration file: All tool versions for a project are specified in a single
.tool-versionsfile, simplifying collaboration and preventing version conflicts. - Ease of migration: Supports existing configuration files like
.nvmrc,.node-version,.ruby-version, making it easier to transition from other version managers. - Automatic version switching: asdf automatically switches tool versions based on the current directory.
- Extensibility through plugins: Ability to add support for new languages and tools through plugins.
- Autocompletion for shells: Supports autocompletion for popular shells (Bash, Zsh, Fish, Elvish).
Disadvantages of asdf:
- Limited dependency support: Does not manage system package dependencies; requires manual installation.
- Complex setup for beginners: Can be difficult to set up and integrate with the shell for beginners.
- Low performance in some cases: Using shims can sometimes be slower than directly running tools.
- Not suitable for all scenarios: Not always optimal for system tools or specific scenarios.
- Less popular: Less known than specialized version managers, which can make it harder to find documentation and support.
Another tool quite similar to asdf is vfox. It supports version management for various programming languages. It also has an MSI installer, unlike asdf, and hence is painless to install for the majority of Windows users. In fact, the function is quite similar to asdf in that it supports Node.js versions by simply changing a configuration.
Comparing Node.js Version Management Tools
Selection of a tool that manages the version of Node.js requires considering every factor affecting performance, speed, and usability. Given below is a detailed comparison of key tools based on several factors:
Performance and Speed:
- NVM: A reliable and flexible tool, but it can be slower when frequently switching versions due to using shell scripts. Suitable for most developers, especially if delays are not critical.
- NVS: Provides good performance for managing Node.js versions in cross-platform environments. Its speed may be lower than tools written in faster languages, but it effectively handles the task and supports automatic version switching.
- fnm: One of the fastest tools due to its Rust implementation. Provides instant version switching, making it ideal for large projects and developers who frequently change Node.js versions.
- Volta: Automatically manages versions, saving time on setup and switching. An ideal choice for teams where automation and version consistency are important.
- asdf: A universal tool for managing versions of many programming languages and tools. Suitable for multi-language projects, but may be slower and harder to set up for working only with Node.js.
Ease of Use:
- NVM: Intuitive and easy to use, especially for beginners. Supports most operating systems and provides many useful commands for version management.
- NVS: Convenient for experienced users thanks to support for automatic version switching and an interactive menu. However, beginners may need time to master the commands.
- fnm: Provides high performance and is convenient for frequent version switching. Suitable for those who value speed and minimal response time.
- Volta: Maximally simplifies version management through automation, reducing the likelihood of errors and saving time. Ideal for teamwork and process automation.
