Tau Installer

@abdoknbgit/tau-installer installs Tau globally while allowing only Tau's reviewed npm lifecycle scripts for that single install command.

Node.js 20.18.1 or newer is required.

Install or update to the latest Tau

npx -y @abdoknbgit/tau-installer@latest

Install an exact Tau version

Tau's updater can pin the release it already selected:

npx -y @abdoknbgit/tau-installer@latest --tau-version 0.92.15

--tau-version accepts an exact semantic version only. Tags and ranges such as latest, ^0.92.15, and 0.92.x are rejected.

Inspect without installing

npx -y @abdoknbgit/tau-installer@latest --dry-run

The installer has no dependencies and no lifecycle scripts of its own. It runs the invoking npm CLI with shell: false and passes the reviewed list through a command-line --allow-scripts option. It never runs npm config set and never changes the user's persistent npm configuration.

For this command only, the installer also disables inherited ignore-scripts and dangerously-allow-all-scripts settings, disables inherited npm dry-run and package-lock-only modes, forces executable bin links, includes supported optional dependencies, and enables strict script policy. Required reviewed scripts can run, while an unreviewed dependency script stops the install.

The installer checks the invoking npm version first. npm 11.16 and newer receive the command-only --allow-scripts list. Older npm versions omit that unsupported option because they run lifecycle scripts normally.

Tau's release tests derive the reviewed list from package-lock.json and fail when a production dependency adds or removes an install script. This keeps the installer policy explicit without changing users' persistent npm configuration.
