Documented steps
Add preinstall, install, or postinstall scripts to run code automatically when the package's dependencies are installed.
npm install and npm ci run the chain preinstall -> install -> postinstall -> prepublish -> preprepare -> prepare -> postprepare after modules load.
If a binding.gyp exists and there is no custom install or preinstall script, npm defaults the install script to node-gyp rebuild.
Run with --ignore-scripts (or npm config set ignore-scripts true) to skip all lifecycle scripts.

Known gotchas
Install scripts execute on every consumer install, not just your own machine, so keep them side-effect-light and idempotent.
As of npm 7 the prepare phase of a local install runs in the background; pass --foreground-scripts to see its output.
install lifecycle does NOT run in global mode for the dependencies script, and the dependencies lifecycle only fires when node_modules actually changed.
