It can be the stepping stone for you to getting started:

Index.html

   
   

    
  

    

      Author:
      
      

      
 Title:
      
      

      
 Body:
      
      

      

      
    
  

Angular code app.js

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
   $scope.submit= function(){
      var data = $.param({
        book: JSON.stringify({
            author: $scope.author,
            title : $scope.title,
            body : $scope.body
        })
      });

      $http.post("/api/book/", data).success(function(data, status) {
        console.log('Data posted successfully');
      })
   }
});

server.js - Nodejs

var express = require('express'); 
var mysql = require('mysql');
var app = express();

var connection = mysql.createConnection({
     host: 'localhost',
     user: '',
     password: '',
     database: 'copedb'
});
connection.connect();

app.post('/api/book', function(req, res, next){
   var cope = req.body.params;
   var query = connection.query('insert into cope set ?', cope, function(err, result) {
     if (err) {
       console.error(err);
       return res.send(err);
     } else {
       return res.send('Ok');
     }
});
app.listen(8080);
