ECOMMERCE Website Using MERN Part-6.1 ( Authentication { Setup } )

In this blog we will be setting up the user by making userModel, userController as well as userRoutes. This blog is gonna be a long one but preety simple as it will be almost same as our products

Step-1 Installing the necessary dependencies

Open up the terminal and install the following dependencies

  1. BcryptJs - For encrypting & decrypting our passwords
  2. Json Web Token - For Authentication
  3. Validator - For validating some fields like name etc
  4. Nodemailer - For sending mails
  5. Cookie Parser
  6. Body Parser

by writing npm i bcryptjs jsonwebtoken validator nodemailer cookie-parser body-parser.

Step-2 After installing we just make the userModel by making a file named userModel.js inside of models folder.

The code for the User Model is below. If you don't understand some lines do let me know in the comments :)

const mongoose = require("mongoose");
const validator = require("validator");

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, "Please Enter Your Name"],
    maxLength: [30, "Name cannot exceed 30 characters"],
    minLength: [4, "Name should have more than 4 characters"],
  email: {
    type: String,
    required: [true, "Please Enter Your Email"],
    unique: true,
    validate: [validator.isEmail, "Please Enter a valid Email"],
  password: {
    type: String,
    required: [true, "Please Enter Your Password"],
    minLength: [8, "Password should be greater than 8 characters"],
    select: false,
  avatar: {
    public_id: {
      type: String,
      required: true,
    url: {
      type: String,
      required: true,
  role: {
    type: String,
    default: "user",
  createdAt: {
    type: Date,

  resetPasswordToken: String,
  resetPasswordExpire: Date,

module.exports = mongoose.model("User", userSchema);
Enter fullscreen mode Exit fullscreen mode

Step-3 Lets make our registerUser function in a new file named userController.js inside of our controllers folder

const ErrorHandler = require("../utils/errorHandler");
const catchAsyncErrors = require("../middleware/catchAsyncErrors");
const User = require("../models/userModel");

// Register User
exports.registerUser = catchAsyncErrors(async (req, res, next) => {
  const { name, email, password } = req.body;

  const user = await User.create({
    avatar: {
      public_id: "This is a sample id",
      url: "profile pic url",

    success: true,
Enter fullscreen mode Exit fullscreen mode

Here we are importing our model as well as our ErrorHandlers.
And inside the function we destructured our req.body and extract the name, email & password and create the user with create({}) where we are sending those values including avatar which we will be doing using cloudinary while doing the front-end.

Step-4 Now lets make userRoutes.js inside of routes folder and write the following code.

const express = require("express");
const router = express.Router();
const { registerUser } = require("../controllers/userController");


module.exports = router;

Enter fullscreen mode Exit fullscreen mode

Its explanation is preety simple, we just imported express and called the Router() and then made the route /register with the registerUser function from userController

Step-5 Now to use this router we write the following code inside of our app.js file
1. const userRoutes = require("./routes/userRoutes)
2. app.use("/api/v1", userRoutes)

Our app.js shall look like this

So our basic Setup is done.
In the Next Blog we will be encrypting the user's password

Discussion (2)

Here begins the interesting part :)

I don't like the fact that once you create a user you return the password in the reply. In general, this does not open a big hole in security, but it is still good not to do it.

Therefore, my advice is to remove the password field from the answer.
I have another remark, but I will wait to see how you develop the topic.

ya ya i will be removing that in the next blog which will probably come by tomorrow. Securing and managing password with auto login will also be included there.
