Package Exports

jsctl

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 (jsctl) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Examples:
  GENERATE

  from your projects root directory:
  sudo jsctl generate -u $USER

  by telling jsctl where to find your pacakge.json:
  sudo jsctl generate -u $USER -d /path/to/project

  or by providing name and scriptpath arguments:
  sudo jsctl generate -u $USER -n example-app -s /path/to/script.js

  a more customized example:
  sudo jsctl generate -u nobody -e 'NODE_ENV=development NODE_PORT=3000'
  --stdout 'journal+console'

  GENERAL

  if you want to manage a service and you are not in its projects root folder,
  you have to provide the name:

  sudo jsctl stop -n example-app
  jsctl cat -n example-app

Local installation example:

$ yarn add jsctl
$ # or
$ npm i --save-dev jsctl

// package.json
{
  "name": "example-app",                                // required
  "main": "path/to/script.js",                          // required
  "scripts": {
    "generate": "sudo ./node_modules/.bin/jsctl generate -u $USER",
    "start": "sudo ./node_modules/.bin/jsctl start",
    "status": "jsctl status",
    "stop": "sudo ./node_modules/.bin/jsctl stop"
  }
}
