nodenv-package-json-engine

This is a plugin for nodenv that detects the Node version based on the engines field of the current tree's package.json file. The $NODENV_VERSION environment variable (set with nodenv shell) and .node-version files still take precedence.

When engines is configured with a range this plugin chooses the greatest installed version matching the range, or exits with an error if none match.

Once you've installed the plugin you can verify that it's working by cding into a project that has a package.json file with engines and does not have a .node-version file. From anywhere in the project's tree, run nodenv which node.
