promised-exec

Promised version of NodeJS child_process exec.

How to install this module?

To install this module use following command at root path of your module:

npm install promised-exec --save

Usage

This module exports function which waits only one argument on input: string with terminal command.

Function returns promise (based on library "q").

If command is invalid, the catch function will be called with object which contains string with error, and default error buffer (argument error of exec callback).

If command is valid, but response of command is error, the catch function will be called with object which contains string with error, and default error buffer (argument error of exec callback).

If command is valid, and response is correct, the the function will be called with string which contains response of command.

Example (correct command):

var exec, promise; exec = require('promised-exec'); promise = exec('ls -l'); promise.then(function (responseString) { /* * Now variable 'responseString' contains string: * * "-rwxrwxrwx 1 root root 29 дек 6 09:58 config.json * -rwxrwxrwx 1 root root 142 дек 6 09:58 gulpfile.js * -rwxrwxrwx 1 root root 224 дек 6 09:58 gulptask.test.js * -rwxrwxrwx 1 root root 796 дек 6 10:34 index.js * -rwxrwxrwx 1 root root 1093 дек 6 09:58 LICENSE * drwxrwxrwx 1 root root 0 дек 6 09:59 node_modules * -rwxrwxrwx 1 root root 713 дек 6 09:58 package.json * -rwxrwxrwx 1 root root 3051 дек 6 10:51 README.md * drwxrwxrwx 1 root root 0 дек 6 10:35 tests" * */ }); . . .

Example (incorrect command):

var exec, promise; exec = require('promised-exec'); promise = exec('some-unknown-command'); promise.catch(function (errorObject) { /* * Now variable 'errorObject' contains object: * * {"buffer": <Buffer>,"string":"Error: Command failed: /bin/sh: some-unknown-command: command not found\n"} * */ }); . . .

Example (incorrect command arguments):

var exec, promise; exec = require('promised-exec'); promise = exec('ls -w'); promise.catch(function (errorObject) { /* * Now variable 'errorObject' contains object: * * {"buffer": <Buffer>,"string":"Error: Command failed: ls: key must be used with argument \"w\"\nUse command \"ls --help\" to get additional information.\n"} * */ }); . . .
