Node website returns “Cannot GET/withTxt” when hosted with xxx.js

This is my code:

 xxx = require('./routes/xxx');

app.get('/myNodePage',routes.eXxxTxt);

app.post('/myNodePage', function(req,res,nextResult){
   xxx.emailHtml(req,res,nextResult);
});

And when i run this i get "Cannot GET / my Node Page". What am i doing wrong? why i am getting this?
