Classes to implement a command line Node.js application

Package Exports

  • @ilg/cli-start-options

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ilg/cli-start-options) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

CLI startup and options processing

A Node.js module with classes to implement a command line Node.js application.

The module exports several classes (like CliApplication, CliCommand, ...) that can be used as base classes for CLI applications.

Prerequisites

A recent Node.js (>7.x), since the ECMAScript 6 class syntax is used.

If this is the first time you hear about Node.js, download and install the the binaries specific for your platform without any concerns, they're just fine.

Easy install

The module is available as @ilg/cli-start-options from the public repository, use npm to install it inside the module where it is needed:

$ npm install @ilg/clis-start-options --save

The module does not provide any executables, and generaly there are few reasons to install it globally.

The development repository is available from the GitHub xpack/cli-start-options-js project.

User info

The module can be included in CLI applications and the classes can be used to derive application classes.

// Equivalent of import { CliApplication, CliCommand, CliHelp, CliOptions } from 'cli-start-options'

const CliApplication = require('@ilg/cli-start-options').CliApplication
const CliCommand = require('@ilg/cli-start-options').CliCommand
const CliHelp = require('@ilg/cli-start-options').CliHelp
const CliOptions = require('@ilg/cli-start-options').CliOptions
const CliOptions = require('@ilg/cli-start-options').CliOptions
const CliError = require('@ilg/cli-start-options').CliError
const CliErrorSyntax = require('@ilg/cli-start-options').CliErrorSyntax
const CliErrorApplication = require('@ilg/cli-start-options').CliErrorApplication
const CliExitCodes = require('@ilg/cli-start-options').CliExitCodes

Developer info

Git repo

$ git clone https://github.com/xpack/cli-start-options-js.git cli-start-options-js.git
$ cd cli-start-options-js.git
$ npm install
$ sudo npm link 
$ ls -l /usr/local/lib/node_modules/@ilg

A link to the development folder should be present in the system node_modules folder.

In projects that use this module under development, link back from the global location:

$ npm link @ilg/cli-start-options

Tests

The tests use the node-tap framework (A Test-Anything-Protocol library for Node.js, written by Isaac Schlueter).

As for any npm package, the standard way to run the project tests is via npm test:

$ cd cli-start-options-js.git
$ npm install
$ npm test

A typical test result looks like:

$ npm run test

> @ilg/cli-start-options@0.1.12 test /Users/ilg/My Files/MacBookPro Projects/xPack/npm-modules/cli-start-options-js.git
> standard && npm run test-tap -s

To run a specific test with more verbose output, use npm run tap:

$ npm run tap test/tap/cmd-copy.js -s

Coverage tests

Coverage tests are a good indication on how much of the source files is exercised by the tests. Ideally all source files should be covered 100%, for all 4 criteria (statements, branches, functions, lines).

To run the coverage tests, use npm run test-coverage:

$ npm run test-coverage

> @ilg/cli-start-options@0.1.12 test-coverage /Users/ilg/My Files/MacBookPro Projects/xPack/npm-modules/cli-start-options-js.git
> tap --coverage --reporter=classic --timeout 600 "test/tap/*.js"

test/tap/cmd-copy.js ................................ 40/40
test/tap/interactive.js ............................. 14/14
test/tap/module-invocation.js ......................... 9/9
test/tap/options-common.js .......................... 24/24
total ............................................... 87/87

Continuous Integration (CI)

The continuous integration tests are performed via Travis CI and AppVeyor.

Standard compliance

The module uses ECMAScript 6 class definitions.

As style, it uses the JavaScript Standard Style, automatically checked at each commit via Travis CI.

Known and accepted exceptions:

  • // eslint-disable-line node/no-deprecated-api to continue using the deprecated domain module

To manually fix compliance with the style guide (where possible):

$ npm run fix

> @ilg/cli-start-options@0.1.12 fix /Users/ilg/My Files/MacBookPro Projects/xPack/npm-modules/cli-start-options-js.git
> standard --fix

Documentation metadata

The documentation metadata follows the JSdoc tags.

To enforce checking at file level, add the following comments right after the use strict:

'use strict'
/* eslint valid-jsdoc: "error" */
/* eslint max-len: [ "error", 80, { "ignoreUrls": true } ] */

Note: be sure C style comments are used, C++ styles are not parsed by ESLint.
