How to make a request in a localhost mysql database - mysql

Question

I am using mysql and request. I want to make a request in my localhost server. I just need to know how to make the get request into the localhost server because I don't understand how, I'm running into a continuous loop.
var connection = mysql.createConnection({
host: 'localhost',
user: 'root',
password: '',
database: 'virtual_currency_price'
});
Request:
router.get('/getprice', function(req, res){
request(connection, function (error, response, body) {
if (!error && response.statusCode == 200){
}
});
});
I'm trying to figure out how to do this but I'm failing very miserably
The table I'm trying to GET from is called "price" and I will be using the datetime to fetch certain prices.

After you establish a connection with your server you can use it to fetch data from database. You don't need to make a request using the module, just use the connection directly to execute queries as below:
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '',
database : 'virtual_currency_price'
});
connection.connect();
connection.query('SELECT * from price', function(err, rows, fields) {
if (err) throw err;
console.log(rows);
});
connection.end();
It's recommended that you create a pool of connections instead and reuse them in your app instead of creating it every time you need to access the DB.
See the docs from github.
