Documented steps
cd into the project
Set the minimum/matching Node version: npm pkg set engines.node='>=20.19' (quote the semver so the shell doesn't interpret it)
Add more engines in the same call, e.g. engines.npm: npm pkg set engines.node='>=20.19' engines.npm='>=10'
Confirm with npm pkg get engines
Known gotchas
engines constraints are advisory by default — npm warns on mismatch but does not refuse to install unless you enable engine-strict (npm config set engine-strict true)
Always quote the version range because chars like >= and || are shell metacharacters
Some registries/publish flows and package managers (pnpm/yarn) read engines to gate installs, so set realistic floor versions your tooling actually supports
