Exec-wait

A simple promiseful execution utility that waits for input from stdout or a HTTP/HTTPS request to return until giving the control to the next command in the chain.

Useful e.g. for test automation process chains etc.

Installation

> npm install exec-wait

Usage

var ghostDriver = exec({
  name: 'Ghostdriver',
  cmd: path.join(require.resolve('phantomjs'), '../phantom/bin',
    'phantomjs' + (process.platform === 'win32' ? '.exe' : '')),
  args: ['--webdriver=4444', '--ignore-ssl-errors=true'],
  monitor: { stdout: 'GhostDriver - Main - running on port 4444' }
});

var cmdAndArgs = require('package.json').scripts.start.split(/\s/),
  testServer = exec({
    name: 'Test server',
    cmd: cmdAndArgs[0],
    args: cmdAndArgs.slice(1),
    monitor: {
      url: 'http://localhost:8080/',
      checkHTTPResponse: false
    },
    httpOptions: {
      rejectUnauthorized: false
    }
  });

testServer.start()
  .then(ghostDriver.start)
  .then(function() {
    // Do something
  })
  .then(ghostDriver.stop)
  .then(testServer.stop);

httpOptions can be used to pass options to http / https modules. e.g. rejectUnauthorized skips certificate validity checks (required for self-signed certificates)
