I am new in Mern development, and getting this "Cannot access 'user' before initialization" error in controller file
Controller/user.js
const user = require('../models/user')
exports.signup = (req,res)=>{
console.log('req.body', req.body);
const user = new user(req.body);
user.save((err, user)=>{
if(err){
return res.status(400).json({
err
})
}
res.json({
user
})
})
}
Route/user.js
const express = require('express');
const router = express.Router();
const {signup} = require('../controllers/user');
router.post("/signup", signup);
module.exports = router;
On line 1 you define a variable named user.
On line 4 you define a different variable also named user in a different scope.
At the other end of line 4 you try to call the value of that variable as a function, but it doesn't have a value yet. Hence the error message.
You intended to call the function in the variable from line 1, but since the one on line 4 shadows it, you are calling that instead.
Don't shadow your variables.
Change the name of one of them.
