node-sys
Universal package installer, get the command for managing packages, or auto install any package, using one command for all platforms. E.g.
sudo apt-get install
!@#$software for Debian-based systems, would benode-sys
!@#$software.
This is mainly focused on initial installation of an Node JS packages that needs additional host software installed. This allows pre and post script install routines. Can also automate the installation of macOS Brew, and Windows Chocolatey package managers.
node-sys
will try to find which system packaging is installed for the given process.platform
. If no system package manager is found, 'No package manager found!'
is returned.
A spawning
cross-platform version of Node's child_process.spawn
that returns a Promise, with additions:
- easily execute as administrator, on
Windows
a pop up UAC window will appear. - pass callbacks, for
stderr
andstdout
ondata
events, any returns will be the reject/resolve result. fork
another script, a Node Js module instance, for additional sub processing base onstderr
orstdout
events.- pass additional callback for the
message
event.
- pass additional callback for the

type checkers.
Install
npm install node-sys
Usage
import { packager } from 'node-sys';
/**
* Gets the system package manager install command.
*
* - 'brew install' on OS X if homebrew is installed.
* - 'sudo apt-get install' on debian platforms.
* - 'sudo yum install' on red hat platforms.
* - 'System OS package manager not found' if no package manager is found.
*
* Throws if `process.platform` is none of darwin, freebsd, linux, sunos or win32.
*/
const sys = packager();
console.log('Do system OS require sudo? ' + sys.sudo);
console.log('The system OS install command: ' + sys.command);
console.log('To fully install a `pandoc` package run: ' + sys.installer + ' pandoc');
Install vim
package onto host, using system's default package manager
- Returns a
Promise
import { installer } from 'node-sys';
// Progress callback for any output doing installation.
// Any value returned in `callback` will be the final resolved output result.
const onprogress = (object) => {
console.log(object.output);
}
installer('vim', onprogress)
.then(function(data){
// returns installation output
console.log(data);
})
.catch(function(err) {
console.log(err);
});
API - spawning
(command, arguments, progressOptions, options)
import { spawning } from 'node-sys';
Spawning
takes an additional argument, progressOptions
, its options
are the same as those of child_process.spawn
plus:
sudo: boolean, // run as administrator
fork: string, // execute an additional module, of Node Js process `fork` IPC communication channel.
onerror: callable, // callback for `stderr.on('data')` event.
onprogress: callable, // callback for `stdout.on('data')` event.
onmessage: callable, // callback for `on('message')` for `fork` event.
Spawning
returns a promise whose result will be any output or any data return in the progress callback.
The progress callback will receive an object with these properties:
spawn:
Object - Spawned child process instance handle.- Access the child process object.
output:
String - Output from stdout.- Output can be altered and if returned will replace the otherwise resolved result.
fork:
Object - An additional forked Node Js process handle, IPC communication channel.- Execute additional processing base off of sub child process output, with module a script.
If there's an error running the child process, received data on stderr, or errors in progress callback, spawning
rejects the returned promise.
General strict
type check
functions
import {
isArray, // True if value is an Array, otherwise false.
isUndefined, // True if the value is undefined, otherwise false.
isBuffer, // True if value is a Buffer, otherwise false.
isArrayBuffer, // True if value is an ArrayBuffer, otherwise false.
isString, // True if value is a String, otherwise false.
isNumber, // True if value is a Number, otherwise false.
isObject, // True if value is an Object, otherwise false.
isObjectOnly, // True if value is a `Object` only, otherwise false, not an Array, Function, or any other type.
isBlob, // True if value is a Blob, otherwise false.
isFunction, // True if value is a Function, otherwise false.
isDate, // True if value is a Date, otherwise false.
isStream, // True if value is a Stream, otherwise false.
isNull, // True if value is a null, otherwise false.
isBool, // True if value is a boolean, otherwise false.
isWindows, // True if platform a Windows OS, otherwise false.
isLinux, // True if platform a Linux OS, otherwise false.
isMac, // True if platform a Apple macOS, otherwise false.
} from 'node-sys';
Find any executable
The sync
from node-which has been exported to where
.
import { where } from 'node-sys';
// Like the unix `which` utility, will be a `string`, or `null` for not found.
let found = where('node');
Use CommonJS require
like before in ESM
import { require } from 'node-sys';
const package = require('package');
CLI Usage
npm i -g node-sys
To display your system package manage command.
$ node-sys
brew install
To actually install an system package.
$ node-sys vim
installing...
To install an System OS package manager.
- Will install chocolatey for Windows OS
