Comment (by netweb):

 My notes from  [ticket:30787#comment:9 #30787] ( Shrinkwrap NPM
 dependencies):
 > Also we should be using at least NodeJS v0.12.x as PostCSS requires this
 v0.12.x or greater, and WordPress includes two node modules that use
 PostCSS, Autoprefixer and RTLCSS.
 >
 > I'd be tempted to actually recommend that we bump up our minimum
 supported NodeJS version to v4.x LTS per the
 [https://nodejs.org/en/blog/community/node-v5/ LTS announcment], this
 brings back compatibility of IO.JS and NodeJS branches and gives us a
 somewhat more dependable NodeJS base that module owners are aware of for
 maintaining backcompat for this NodeJS version.

 I just hit upon the NodeJS LTS document:
 https://github.com/nodejs/LTS/blob/master/README.md which details the LTS
 plan and roadmap which clears things up a bit on whats whats in regard to
 the timelines of NodeJS versions

 ----

 Grepping the `/node_modules` folder shows the vast majority of packages
 require NodeJS `>=0.10`, and 4 require `>=0.12`

 * PostCSS requires NodeJS `>=0.12` so that includes `autoprefixer`,
 `grunt-rtlcss`, and `grunt-postcss`.

 * `get-stdin` is a dependant in the `grunt-contrib-imagemin` tree and also
 requires NodeJS `>=0.12`

 None required NodeJS v4.x or greater so we can use NodeJS `>=0.12` for
 now, and switch to v4.x LTS once that need arises.

 ----

 Complimentary to this ticket could be to add
 [https://www.npmjs.com/package/grunt-check-dependencies grunt-check-
 dependencies] via [https://www.npmjs.com/package/check-dependencies check-
 dependencies]:

 > ''The checkDependencies task checks if the package has all necessary
 dependencies installed in right versions. If that's not the case, the task
 fails and advises to run npm install.''

 It was added to BuddyPress in [buddypress:changeset:10399] and the Grunt
 task is run before any other Grunt tasks, if it fails your prompted with
 the advisory to run `npm install`, works quite well and takes some of the
 pain out of working out maintaining your npm workflow.
