Can't Post data from postman to database with express

I am unable to Post data from postman to mysql database I'm using express

I have tried using Body and Raw x-wwww-form-urlencoded

Here is my code (Yes everything is in the same file I know it's not a good thing I'm sorry)

var app = express();
var bodyParser = require('body-parser');
var mysql = require('mysql');

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));


// default route
app.get('/', function (req, res) {
    return res.send({ error: true, message: 'hello' })
});
// connection configurations
var dbConn = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: '',
    database: 'testexpress'
});

// connect to database
dbConn.connect(); 



// Add a new user  
app.post('/user', function (req, res) {

    let user = req.body.user;

    if (!user) {
        return res.status(400).send({ error:true, message: 'Please provide user' });
    }

    dbConn.query("INSERT INTO users SET ? ", { user: user }, function (error, results, fields) {
        if (error) throw error;
        return res.send({ error: false, data: results, message: 'New user has been created successfully.' });
    });
});

// set port
app.listen(3000, function () {
    console.log('Node app is running on port 3000');
});

module.exports = app;

here is my screenshot error from Postman and my database

Modify your code like this. It should work

// Add a new user  
app.post('/user', function (req, res) {

    let user = [req.body]
    console.log(user);

    if (!user) {
        return res.status(400).send({ error:true, message: 'Please provide user' });
    }

    dbConn.query("INSERT INTO users SET ? ", user, function (error, results, fields) {
        if (error) throw error;
        return res.send({ error: false, data: results, message: 'New user has been created successfully.' });
    });
});

Your code is showing this error message error:true, message: 'Please provide user because everytime in your code the condition if (!user) is executed, because let user = req.body.user is going to give undefined value so you are going to get that error and the rest of the code will never execute then .
