Gulp-protractor not starting webdriver-manager - selenium

Question

I'm trying to run protractor automatically using gulp-protractor plugin. This whole process works fine when using protractor commands and explicitly running the web drivers individually.
The same works when running using gulp-protractor, provided ie webdriver is started manually in background before triggering the gulp task.
Below is the code snippet of my Gulp task
var protractor = require("gulp-protractor").protractor;
var webdriverupdate = require("gulp-protractor").webdriver_update;;
var webdriver_standalone = require("gulp-protractor").webdriver_standalone;
// This task is to update & run the webdriver
gulp.task('webdriver_standalone', webdriver_standalone);
gulp.task('webdriverUpdate', ['webdriver_standalone'], function () {
browsers: ['chrome', 'ie']
});
//for running protractor E2E test cases
gulp.task('protractor', function (callback) {
gulp
.src(['./e2e/sanity/shared/*.spec.ts',
'./e2e/sanity/app-header/*.spec.ts',
])
.pipe(protractor({
'configFile': 'Protractor.conf.js',
}))
.on('error', function (e) {
console.log(e);
})
.on('end', callback);
});
gulp.task('default',['webdriverUpdate','protractor']);
Below is the code snippet of my protractor.config.js
const { SpecReporter } = require('jasmine-spec-reporter');
exports.config = {
allScriptsTimeout: 1100,
suites: {
shared: ['./e2e/sanity/shared/*.ts'] ,
appheader: ['./e2e/sanity/app-header/*.spec.ts']
},
multiCapabilities:
[{
seleniumAddress: 'http://localhost:5555/',
'browserName': 'internet explorer',
'platform': 'windows 10',
'version': '11',
'ignoreProtectedModeSettings': true,
},
{
seleniumAddress: 'http://localhost:4444/wd/hub',
'browserName': 'chrome',
'ignoreProtectedModeSettings': true,
}],
};
How do I run webdriver standalone task ahead of protractor task via gulp??

Answer 1

I used gulp with gulp-angular-protractor like below, hope this helps. It will work for gulp-protractor plugin as well.
//Gulpfile
var gulp = require('gulp');
var gulpProtractor = require('gulp-angular-protractor');
var paths = require('../paths.js');
// Execute e2e Tests
gulp.task('e2e-test', function(callback) {
gulp.src(paths.tests)
.pipe((gulpProtractor({
configFile: 'protractor.conf.js'
})).on('error', function(e) {
console.log(e);
}).on('end', callback));
});
gulp.task('webdriver-update', gulpProtractor.webdriver_update);
gulp.task('webdriver-standalone', ['webdriver-update'], gulpProtractor.webdriver_standalone);
//paths.js:
module.exports = {
tests: 'test/e2e/**/*.spec.js'
};
