"""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`.
