Node.js plugin for asdf version manager

The plugin properly validates OpenPGP signatures to check the authenticity of the package. Requires gpg to be available during package installs

• GNU Core Utils - brew install coreutils
• GnuPG - brew install gpg

• dirmngr - apt-get install dirmngr
• GnuPG - apt-get install gpg

Install the plugin:

asdf plugin-add nodejs https://github.com/asdf-vm/asdf-nodejs.git

Import the Node.js release team's OpenPGP keys to main keyring:

bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring

If you installed asdf with brew adjust the path to the Node.js plugin:

bash /usr/local/opt/asdf/plugins/nodejs/bin/import-release-team-keyring

Check asdf readme for instructions on how to install & manage versions of Node.js.

When installing Node.js using asdf install, you can pass custom configure options with the following env vars:

• NODEJS_CONFIGURE_OPTIONS - use only your configure options
• NODEJS_EXTRA_CONFIGURE_OPTIONS - append these configure options along with ones that this plugin already uses
• NODEJS_CHECK_SIGNATURES - strict is default. Other values are no and yes. Checks downloads against OpenPGP signatures from the Node.js release team.
• NODEJS_ORG_MIRROR - official mirror https://nodejs.org/dist/ is default. If you are in China, you can set it to https://npm.taobao.org/mirrors/node/.

asdf uses the .tool-versions for auto-switching between software versions. To ease migration, you can have it read an existing .nvmrc or .node-version file to find out what version of Node.js should be used. To do this, add the following to $HOME/.asdfrc:

legacy_version_file = yes

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:

lodash
request
express

The gpg commands above imports the OpenPGP public keys in your main OpenPGP keyring. However, you can also use a dedicated keyring in order to mitigate this issue.

To use a dedicated keyring, prepare the dedicated keyring and set it as the default keyring in the current shell:

export GNUPGHOME="${ASDF_DIR:-$HOME/.asdf}/keyrings/nodejs" && mkdir -p "$GNUPGHOME" && chmod 0700 "$GNUPGHOME"

# Imports Node.js release team's OpenPGP keys to the keyring
bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring

Again, if you used brew to manage the asdf installtion use the following bash commands:

export GNUPGHOME="bash /usr/local/opt/asdf/keyrings/nodejs" && mkdir -p "$GNUPGHOME" && chmod 0700 "$GNUPGHOME"

# Imports Node.js release team's OpenPGP keys to the keyring
bash /usr/local/opt/asdf/plugins/nodejs/bin/import-release-team-keyring

• Verifying Node.js Binaries.
• Only versions >=0.10.0 are checked. Before that version, signatures for SHA2-256 hashes might not be provided (and can not be installed with the strict setting for that reason).

This behavior can be influenced by the NODEJS_CHECK_SIGNATURES env var which supports the following options:

• strict - (default): Check signatures/checksums and don’t operate on package versions which did not provide signatures/checksums properly (< 0.10.0).
• no - Do not check signatures/checksums
• yes- Check signatures/checksums if they should be present (enforced for >= 0.10.0)
