Node.js plugin for asdf version manager
After installing asdf, install the plugin by running:
asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git
Check asdf readme for instructions on how to install & manage versions of Node.js at a system and project level.
When compiling a version from source, you are going to need to install all requirements for compiling Node.js (be advised that different versions might require different configurations). That being said,
node-build does a great job at handling edge cases and compilations rarely need a deep investigation.
node-build already has a handful of settings, in additional to that
asdf-nodejs has a few extra configuration variables:
ASDF_NODEJS_LEGACY_FILE_DYNAMIC_STRATEGY: Enable and choose the strategy for dynamic/partial versions in legacy version files. Either
latest_available. For more info check the Partial and codename versions section
ASDF_NODEJS_VERBOSE_INSTALL: Enables verbose output for downloading and building. Any value different from empty is treated as enabled.
ASDF_NODEJS_FORCE_COMPILE: Forces compilation from source instead of preferring pre-compiled binaries
ASDF_NODEJS_NODEBUILD_HOME: Home for the node-build installation, defaults to
$ASDF_DIR/plugins/nodejs/.node-build, you can install it in another place or share it with your system
ASDF_NODEJS_NODEBUILD: Path to the node-build executable, defaults to
ASDF_NODEJS_SKIP_NODEBUILD_UPDATE: Skip trying to update nodebuild prior to list-all and install. If enabling this var, you might need to update nodebuild manually to get newly released versions
ASDF_NODEJS_CONCURRENCY: How many jobs should be used in compilation. Defaults to half the computer cores
NODEJS_ORG_MIRROR: (Legacy) overrides the default mirror used for downloading the distibutions, alternative to the
NODE_BUILD_MIRROR_URLnode-build env var
asdf uses a
.tool-versions file for auto-switching between software versions. To ease migration, you can have it read an existing
.node-version file to find out what version of Node.js should be used. To do this, add the following to
legacy_version_file = yes
Partial and codename versions
Many version managers allow you to use partial versions (e.g.
v10) or NodeJS
lts/hydrogen) in version files, which are resolved at runtime.
However, this can be risky as it is not guaranteed that all developers will use
the same version, leading to non-reproducibility. In
asdf, we prioritize
reproducibility, so you cannot use partial versions or codenames in a
To address this, we offer an escape hatch for legacy version files. If you are
comfortable with non-reproducibility issues, you can choose between strategies
in a custom environment variable
can export this variable from your shell rc file and it will become the default
This option is only available for legacy version files (.nvmrc and .node-version, at the moment), for that you will need to set
yesin your .asdfrc config file. More info on the official docs
.tool-versionsfile will never support non-deterministic versions, if they were supported in the past that was an unintentional side-effect
The possible values for this variable are:
latest_installed: Will get the latest version already installed that matches the version query. Just installing a new version that matches the dynamic version would be enough to update it. If no matching version is installed it fallbacks to the latest version available to download.
latest_available: Will get the latest version available for installation that matches the version query, this means that when a new NodeJS version gets released you will need to install it before running any command
It is important to be aware of the risks of non-reproducibility. Debugging can become more challenging and bugs may leak into production if the deployed node version differs from the one used in development. Ideally, maintainers should be encouraged to pin the version to a specific release to avoid these issues.
If non-reproducibility is not a concern for you, you can use one of the following resolve scripts in your shell rc file:
NOTE: Partial versions and codenames only work for legacy version files:
Default npm Packages
asdf-nodejs can automatically install a set of default set of npm package right after installing a Node.js version. To enable this feature, provide a
$HOME/.default-npm-packages file that lists one package per line, for example:
You can specify a non-default location of this file by setting a
Running the wrapped node-build command
We provide a command for running the installed
asdf nodejs nodebuild --version
node-build advanced variations
node-build has some additional variations aside from the versions listed in
asdf list-all nodejs (chakracore/graalvm branches and some others). As of now, we weakly support these variations. In the sense that they are available for install and can be used in a
.tool-versions file, but we don't list them as installation candidates nor give them full attention.
Some of them will work out of the box, and some will need a bit of investigation to get them built. We are planning in providing better support for these variations in the future.
To list all the available variations run:
asdf nodejs nodebuild --definitions
Note that this command only lists the current
node-build definitions. You might want to update the local
node-build repository before listing them.
Manually updating node-build definitions
Every new node version needs to have a definition file in the
asdf-nodejs already tries to update
node-build on every new version installation, but if you want to update
node-build manually for some reason we provide a command just for that:
asdf nodejs update-nodebuild
In the past
asdf-nodejs checked for signatures and integrity by querying live keyservers.
node-build, on the other hand, checks integrity by precomputing checksums ahead of time and versioning them together with the instructions for building them, making the process a lot more streamlined.
Resolving latest available LTS version in a script
This plugin adds a custom subcommand
asdf nodejs resolve lts. If you want to know what is the latest available LTS major version number you can do this:
# Before checking for aliases, update nodebuild to check for newly releasead versions
asdf nodejs update-nodebuild
asdf nodejs resolve lts
# outputs: 20.9.0
You also have the option of forcing a resolution strategy by using the flags
# Outputs the latest version installed locally which is a LTS
asdf nodejs resolve lts --latest-installed
# Outputs the latest version available for download which is a LTS
asdf nodejs resolve lts --latest-available
If you're using Node.js' corepack to install
pnpm, you'll need to reshim after running
corepack prepare, example:
corepack prepare pnpm@latest --activate
asdf reshim nodejs
