Run protractor in localhost server during countinuous integration

I have been studying protractor and I have wrote some tests in with our production web app. Now I want to integrate this tests on our continuous integration. If the tests fail it should not continue to continuous release.

To achieve this I planned to run the same test in local server with the target version that is going to production. My project is coded in angularjs. My package.json file has a script to start a local server and other to test but I'm not being able to wait the server complete to up before running my tests.

Te question is: How can I run my tests in localhost web server?

My selenium config file

exports.config = {
    framework: 'jasmine',
    seleniumAdress: 'http://localhost:4444/wd/hub',
    suites: {
        fluxos: './specs/fluxos/spec.js',
        validacoes: './specs/validacoes/spec.js'
    },
    capabilities: {
        browserName: 'chrome'
    },
}

My package.json
