A quick Node script to allow multi-environment deploys with now

deploy.js

#! /usr/bin/env node
'use strict';

const program = require('commander');
const fs = require('fs');
const { spawn } = require('child_process');

program
  .version('1.0.0')
  .option('-e, --environment <environment>', 'Environment to deploy to')
  .parse(process.argv);

const file = `now.${program.environment}.json`;
fs.createReadStream(file).pipe(fs.createWriteStream('now.json')); 

const deploy =  spawn('now && now alias', { shell: true, stdio: 'inherit' });

deploy.on('close', () => fs.unlink('now.json', (error) => { if (error) throw error }));

package.json

{
  "devDependencies": {
    "commander": "latest"
  }
}

Usage

This assumes that you have created now.${environment}.json configurations in your current directory.

$ node deploy.js -e production
$ node deploy.js -e staging

Simple and so useful. Thanks!
