Logs for Protractor - selenium

Question

I am new to protractor and want to create logs for my test cases. I used if and else to write logs. I wanted to know if there is any better way of writing logs for protractor test cases?
My Code:
var colors = require('colors/safe');
var mapFeedBackpage=require('./mapFeedBack-page.js')
describe("Map feedback Automation",function()
{
var mapFeedBack= new mapFeedBackpage();
it("Check if the Url works ",function() //spec1
{
console.log("Checking the url :"+browser.params.url+'\n')
browser.get(browser.params.url);
browser.getCurrentUrl().then(function(value){
if(/report/.test(value) === false) {
fail("Result: URL doesnt works-FAIL \n");
}
else
{
console.log(colors.green("PASS :")+browser.params.url+ "is reachable \n");
}
});
});
it("test browser should reach report road option",function() //spec2s
{
console.log("Checking if road report option is available \n");
mapFeedBack.REPORT_ROAD.click();
expect(browser.getCurrentUrl()).toContain("report_road");
browser.getCurrentUrl().then(function(value){
if(/report_road/.test(value) === false) {
fail("Result: URL doesnt works-FAIL");
}
else
{
console.log(colors.green("PASS")+" Road report option is available");
}
});
});

Yes, you can use https://www.npmjs.com/package/log4js which is basically log4j module for nodejs apps. Since protractor is nodejs program it would certainly support this. It's very easy to implement this-
var log4js = require('log4js');
var logger = log4js.getLogger();
logger.debug("Some debug messages");
or you could write a custom logger:
var logger = exports;
logger.debugLevel = 'warn';
logger.log = function(level, message) {
var levels = ['error', 'warn', 'info'];
if (levels.indexOf(level) >= levels.indexOf(logger.debugLevel) ) {
if (typeof message !== 'string') {
message = JSON.stringify(message);
};
console.log(level+': '+message);
}
}
and then use this in your scripts as :
var logger = require('./logger');
logger.debugLevel = 'warn';
logger.log('info', 'Everything started properly.');
logger.log('warn', 'Running out of memory...');
logger.log('error', { error: 'flagrant'});
