How to use for package.json bin script?

[philipptrenz]

Hey there,

I want to ship electron-prebuilt-compile within my npm package and define how to start from cli with node. What I'm searching for is something similar to this cli.js file:

#!/usr/bin/env node

var spawn = require('child_process').spawn
var electron = require('electron-prebuilt')
var join = require('path').join

var app = spawn(electron, ['main.js'], { 
  stdio: 'inherit',
  cwd: join(__dirname) 
}).on('exit', function (i, m) {
  process.exit()
})

so I can define in my package.json

"bin": {
    "my-startup-command": "./cli.js"
  },

I tried to just swap electron-prebuilt to electron-prebuilt-compile but it results in the following error:

child_process.js:360
    throw new TypeError('"file" argument must be a non-empty string');
    ^

TypeError: "file" argument must be a non-empty string

    at Function.Module.runMain (module.js:605:10)
    at startup (bootstrap_node.js:158:16)

Any suggestions? Thanks!

Found a solution:

#!/usr/bin/env node

var spawn = require('child_process').spawn
var join = require('path').join

var app = spawn('npm', ['start'], { 
  stdio: 'inherit',
  cwd: join(__dirname, '..') 
}).on('exit', function (i, m) {
  process.exit()
})
