Hello I am new to NodeJs. Currently I am working in node with Express framework. I installed the express-back package in my project and now I want to send send back data to view from where post request fired. Below is my code that I write:

routes.js

router.post('/register/user',Rules.UserRules.registerUser,UserController.registerUser)

UserController.js

const {check, validationResult} = require('express-validator');
registerUser = function (req, res, next) {

    // Validate request parameters, queries using express-validator
    const errors = validationResult(req)
    console.log("==== errors ===")
    console.log(errors.array())
    if (!errors.isEmpty()) {
        console.log("==== erorror founded ====")
        return res.redirect('/signup',{errors:errors})
    }else{
        console.log('--- form body ----')
        console.log(req.body)
    }

}
module.exports = {registerUser}

When I submit my form to this route then control moves to UserController and I validations fails then I want to send it back to view without defining the redirect path I just want to send it back to view from where request received with errors. But I did not find any useful solution yet. Is there any idea that how I can achieve this target. Suggest any useful link for nodejs beginner.

use res.send(errors) it send errors to client at this route. but if you want to redirect it to another route and then send it to client you have to create /signup route and use res.send(errors) it send errors to client. by default ``` res```` will redirect to redirected route. 

router.post('/signup', (req, res)=>{
//send error or do somethings.
res.json(req.body.errors);
})
