exeggcute
A node.js module to make executing shell commands a breeze!
It simply wraps child_process.exec with a promise so there are zero dependencies besides node!
Installation
Use npm as usual to save the package to your dependencies:
npm install --save exeggcuteUsage
Windows (note the directory)
const exec = require('exeggcute').exec;
var dir = 'c:/code/';
var cmd = 'git clone https://github.com/styfle/exeggcute';
exec(cmd, dir);Linux (note the directory)
const exec = require('exeggcute').exec;
var dir = '/code/';
var cmd = 'git clone https://github.com/styfle/exeggcute';
exec(cmd, dir);ES6 Import (note the import)
import {exec} from 'exeggcute';
var dir = '/code/';
var cmd = 'git clone https://github.com/styfle/exeggcute';
exec(cmd, dir);What's with the name?
The name exeggcute is named after the pokemon, Exeggcute. You can see more code/projects named after pokemon at repokemon.
Why did you make this?
I wanted to execute a chain of commands that reads nicely and not worry about syntax. The node core APIs do not use promises so it's easy to get into callback hell. exeggcute makes it easy to write a RESTful API that executes several commands in a row and fails if any one command in the chain fails.
Advanced Usage Example
Below is an example that mirrors code from the originRepo to the targetRepo.
This is a hook that runs for each push of a branch or tag to the originRepo and will then push that branch/tag to the targetRepo.
hasDir(repoDir)
.then(exists => {
if (!exists) {
return exec(`git clone ${originRepo}`, baseDir)
.then(() => exec(`git remote add target ${targetRepo}`, repoDir))
}
return Promise.resolve(exists);
})
.then(() => exec(`git checkout ${branch}`, repoDir))
.then(() => exec(`git pull origin ${branch}`, repoDir))
.then(() => exec(`git push target ${branch}`, repoDir))
.then(() => exec(`git pull origin --tags`, repoDir))
.then(() => exec(`git push target --tags`, repoDir))
.catch((err) => console.error('Oh no! ', err));
