Pseudocode: Implement Login/Signup Feature

Objective:

Implement a login and signup feature that allows users to create an account and log in to the website. Ensure that user credentials are securely handled and stored in the database.

Steps:

1. Define the User Schema in Mongoose

• User Schema Structure:

  • Fields:
    • username: Unique identifier for the user (e.g., String, required)
    • email: User's email address (e.g., String, required, unique)
    • password: User's hashed password (e.g., String, required)
    • createdAt: Timestamp for when the account was created (e.g., Date, default: current date/time)

• Mongoose Schema Example:

  const mongoose = require('mongoose');
  const bcrypt = require('bcryptjs');
  
  const userSchema = new mongoose.Schema({
      username: {
          type: String,
          required: true,
          unique: true
      },
      email: {
          type: String,
          required: true,
          unique: true
      },
      password: {
          type: String,
          required: true
      },
      createdAt: {
          type: Date,
          default: Date.now
      }
  });
  
  // Pre-save hook to hash the password before saving to the database
  userSchema.pre('save', async function(next) {
      if (!this.isModified('password')) return next();
      this.password = await bcrypt.hash(this.password, 10);
      next();
  });
  
  // Method to compare entered password with the hashed password
  userSchema.methods.matchPassword = async function(enteredPassword) {
      return await bcrypt.compare(enteredPassword, this.password);
  };
  
  const User = mongoose.model('User', userSchema);
