I am new to mean stack development and facing some issues. When I try to run "api/users/login" in Postman, it shows an error saying "Username or password is invalid!". Additionally, when attempting to register using "register/users/register", it gives a message stating "user is already exist". How can I resolve these problems?
Here is my code :
user.router.ts
import {Router} from 'express';
import { sample_users } from '../data';
import jwt from 'jsonwebtoken';
import asyncHandler from 'express-async-handler';
import { User, UserModel } from '../models/user.model';
import { HTTP_BAD_REQUEST } from '../constants/http_status';
import bcrypt from 'bcryptjs';
const router = Router();
// Routes for seeding data
router.get("/seed", asyncHandler(
async (req, res) => {
const usersCount = await UserModel.countDocuments();
if(usersCount > 0){
res.send("Seed is already done!");
return;
}
await UserModel.create(sample_users);
res.send("Seed Is Done!");
}
))
// Route for user login
router.post("/login", asyncHandler(
async (req, res) => {
const {email, password} = await req.body;
// Check if the user exists and validate the password
}
))
// Route for user registration
router.post('/register', asyncHandler(
async (req, res) => {
}
))
export default router;
user.service.ts
import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { ToastrService } from 'ngx-toastr';
import { BehaviorSubject, Observable, tap } from 'rxjs';
import { USER_LOGIN_URL, USER_REGISTER_URL } from '../shared/constants/urls';
import { IUserLogin } from '../shared/interfaces/IUserLogin';
import { IUserRegister } from '../shared/interfaces/IUserRegister';
import { User } from '../shared/models/User';
@Injectable({
providedIn: 'root'
})
export class UserService {
// Methods for user login, registration, and logout
}
login.component.ts
import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { ActivatedRoute, Router } from '@angular/router';
import { UserService } from 'src/app/services/user.service';
@Component({
selector: 'app-login-page',
templateUrl: './login-page.component.html',
styleUrls: ['./login-page.component.css']
})
export class LoginPageComponent implements OnInit {
// Login form component
}
auth.guard.ts
import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { UserService } from 'src/app/services/user.service';
@Injectable({

})
export class AuthGuard implements CanActivate {
// Guard to check authentication status
}
