What should I use to authenticate user in login with nodejs

I'm using MySQL in ExpressJS. I've inserted data in my database and now I need to authenticate the user with the data present in the database, e.g.:

username: john 
password: 123 

Now when ever john logs in with the username and password it should check whether it is present in MySQL or not as I've a little bit background in PHP in which we use the following approach:

$query=mysql_query("SELECT * from login WHERE username='".$_POST['username']."' AND password='".$_POST['password']."' ") or die(mysql_error());

if(mysql_fetch_row($query)>0){
    echo "Login Sucessfully";
        }>
    else{
            echo "Wrong Id or Password";
        }
