Node Js : MYSQL is not connecting

Question

I am new to node.js, so i am stuck at this point. I have tried to learn it from these sites Code Mentor and Github

Till now i have done this :

var mysql = require('mysql');

var app = express();

// Database operations
var connection = mysql.createConnection({
  host : 'localhost',
  port : '8888',
  user : 'sharad',
  password : 'teks',
  dbName : 'FirstDataBase'
});

connection.connect(function (error) {
  if (error){
    console.error('error connecting :' + error.stack);
    return;
  }
  console.log('Connected as id :'+ connection.threadId);
});

app.get("/",function(request,response){
  console.log(' saving');
  var post  = {from:'me', to:'you', msg:'hi'};
  connection.query('INSERT INTO FirstDataBase SET ?', post, function(err, result) {
    if (err) throw err;
  });
});

app.get("/",function(request,response){
  connection.query('SELECT * from FirstDataBase', function(err, rows, fields) {
    connection.end();
    if (!err)
      console.log('The solution is: ', rows);
    else
      console.log('Error while performing Query.');
  });
});

app.listen(8888);

I can not see any log i am printing in my code. Any help would be appreciated. Thanks

Answer 1

I resolve this issue like this

install mysql:

npm install mysql

var mysql = require('mysql');

let connection = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    port: '8888',  /* port on which phpmyadmin run */
    password: 'root',
    database: 'dbname',
    socketPath: '/Applications/MAMP/tmp/mysql/mysql.sock' //for mac and linux
});

connection.connect(function(err) {
    if (err) {
      return console.error('error: ' + err.message);
    }

    console.log('Connected to the MySQL server.');
  });
