so i am doing Timestamp Microservice

and here is my code

    var express =require('express');
    var moment = require('moment');

    var app =express();

    app.get('/',function(req,res){
        res.sendFile(__dirname+'/info.html');
    })

    app.get('/:input',function(req,res){
        // res.send(req.params.input);
        //moment.unix(1450137600).format("MMM D YYYY");
        //moment("December 15, 2015").format('X');
        var isValidDate =moment(''+req.params.input).isValid();
        var isValidUnixDate =moment.unix(''+req.params.input).isValid();
        // console.log(req.parms.input);
        if(isValidDate || isValidUnixDate){
        if(isValidUnixDate){
            res.send('unix :'+req.params.input+' natural: '+moment.unix(''+req.params.input).format('MMM D YYYY'));
        }else{
            res.send('unix :'+moment(''+req.params.input).format('X')+' natural: '+req.params.input);  
        }
        }else{
            res.send('invalid date. Try again.');
        }
    })


    app.listen(8080);

now it is working fine. it give me the output as I wanted
but in back end I got some warning in console. Can’t fig out exactly why this happening?
