New project

So far this is a rough guide, a set of ideas, nothing more.

Recommended stuff

scoped package: npm init with --scope=prepair
eslint, eslint semistandard (until we make an eslint plugin from the @prepair lint style)
mocha, comocha, chai, sinon for unit testing (use babel register in test setup or in the opts file)
try to stay browserless, if not possible, use jsdom, phantom is a last resort
husky for commit hooks
standard-version for release (TODO semantic-release without CI?)
npm tasks: dev, lint, test, test:watch, build, release
package dist (or lib) for es2015-ie; no polyfills.
libs that include functionality for both node and the browser MUST be transpiled, libs that are to be used in the node context only are fine with node6 (or current lts)
make sure that your npm run scripts are working cross platform. If you need any executables not supplied with other systems (like grep for example), write a helper script. cross-env will not flow through && command delimiters.
