"""The nodejs plugin is useful for node/npm based parts.
The plugin uses node to install dependencies from `package.json`. It
also sets up binaries defined in `package.json` into the `PATH`.
This plugin uses the common plugin keywords as well as those for "sources".
For more information check the 'plugins' topic for the former and the
'sources' topic for the latter.
Additionally, this plugin uses the following plugin-specific keywords:
- node-packages:
(list)
A list of dependencies to fetch using npm.
- node-engine:
(string)
The version of nodejs you want the snap to run on.
- npm-run:
(list)
A list of targets to `npm run`.
These targets will be run in order, after `npm install`
- npm-flags:
(list)
A list of flags for npm.
- node-package-manager
(string; default: npm)
The language package manager to use to drive installation
of node packages. Can be either `npm` (default) or `yarn`.
