get logged in ID from jwt so that only logged in user can see particular data in nodejs - sql

Question

I am using nodejs, jwt and mysql.
I want the current logged in user ID soo that I can show the data respective to it.
This is my code where SQL logic is written and here I am expecting to get a current user ID.
const pool = require('../../dbconfig/dbconfig');
module.exports = {
getProfile : (callBack) => {
var sql = 'SELECT name, shopStatus, phone, shopaddress.shopNo, shopaddress.complex, shopaddress.landmark, shopaddress.street, shopaddress.area, shopaddress.city FROM shop INNER JOIN shopaddress ON shop.id = shopaddress.shop_id WHERE shop.id = ?'
var insertSql = [ /* how can i get ID here.. */ ]
pool.query(sql, insertSql, (err, results, fields) => {
if(err) {
return callBack(err)
}
return callBack(null, results)
})
}
}
this happens to be jwt middleware code
const jwt = require('jsonwebtoken')
const config = require('../../config')
module.exports = {
isAuth: (req, res, next) => {
let token = req.get("authorization");
if (token) {
// Remove Bearer from string
token = token.slice(7);
jwt.verify(token, config.secret, (err, decoded) => {
if (err) {
return res.json({
status: 'error',
message: "Invalid Token..."
});
} else {
req.decoded = decoded;
next();
}
});
} else {
return res.json({
status: 'error',
message: "Access Denied! Unauthorized User"
});
}
}
};
and this is controller
const shopService = require('./shop.service')
module.exports = {
shopProfile : (req, res) => {
shopService.getProfile((err, results) => {
if(err){
return res.status(500).json({
status : 'error',
error : err,
message : 'Database connection error'
})
}
return res.status(200).json({
status:'success',
data : results
})
})
}
}
