script-help

Outputs entire or filtered npm scripts list with customizable documentation to the console. Documentation structure is based on conventions that have been used for decades in help messages and man pages as collected at http://docopt.org.

Why

• Highly accessible documentation
• Unable to add comments to package.json
• Can be dificult to understand intent from "scripts"
• Explain available "options" (-s to run in silent, etc.)

  "scripts": {
    "help": "npm run script-help"

Help for "Test" Script

Run .spec files in Karma

Usage:
    npm run test

Options:
    --[noBail | nb]    Karma will not bail (halt watch) when there is a
                       compilation error.

Examples:
    npm run test nav   Tests will only be run for "*.spec" within the nav folder.

Tips:
    Run in silent mode to prevent the NPM noise.
