Answer 1

const protractorFlake = require('protractor-flake'),
    baseUrl = process.argv[2],
    maxAttempts = process.argv[3];

if (process.argv.length > 2) {
    console.info('Launching protractor with baseUrl: %s, maxAttempts: %d', baseUrl, maxAttempts);

    protractorFlake({
        maxAttempts: maxAttempts,
        parser: 'multi',
        protractorArgs: [
        './protractor.conf.js',
        '--baseUrl',
        baseUrl
    ]
    }, function (status, output) {
        process.exit(status);
});
} else {
    console.error(`
        Usage: protractor-wrapper <baseUrl>
    `);
}

const Launcher = require("protractor/built/launcher");
Launcher.init('path/to/conf');

Answer 3

It will not be possible. I tried to do that but by reading the protractor source code there is no way to perform this.

https://github.com/angular/protractor/blob/master/lib/launcher.js#L107

This function is called with your config as a json object, but as you can see it calls a bunch of process.exit, according to this it will not be possible to run this without at least forking your process.

My solution for programmatically call protractor is the following:

var npm = require('npm');
var childProcess = require('child_process');
var address = ...some address object
var args = ['--baseUrl', url.format(address)];

npm.load({}, function() {
  var child = childProcess
  .fork(path.join(npm.root, 'protractor/lib/cli'), args)
  .on('close', function(errorCode) {
    console.log('error code: ', errorCode);
  });
  process.on('SIGINT', child.kill);
});
