Hello! How can I assist you today?


give a express app - with habits tracker - + a social media - runned by viewers - where everyone can upload images of habits - include atleadst 3 habits to base prodcut - also anyone can make streaks and upload their photos doing Tasks


Sure! I can help you create an Express.js application that functions as a habit tracker with social media features. Users will be able to:

Register and log in to their accounts.
Track at least three default habits.
Create custom habits.
Upload images of themselves completing tasks.
Maintain streaks for habits.
View and interact with other users' habit progress (social media aspect).
Below is a step-by-step guide to building this application.

├── config/
│   └── passport.js
├── models/
│   ├── Habit.js
│   └── User.js
├── routes/
│   ├── habits.js
│   ├── index.js
│   └── users.js

│   │   └── register.ejs
│   ├── dashboard.ejs
│   └── index.ejs
├── public/
│   ├── uploads/
│   └── css/
└── package.json
4. Create the Server Entry Point (app.js)

// app.js
const express = require('express');
const mongoose = require('mongoose');
const flash = require('connect-flash');
const session = require('express-session');
const passport = require('passport');
const methodOverride = require('method-override');
const path = require('path');

const app = express();

// Passport Config
require('./config/passport')(passport);

// Database Config
const db = 'mongodb://localhost:27017/habit_tracker_social';

// Connect to MongoDB
mongoose.connect(db, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('MongoDB Connected'))
  .catch(err => console.log(err));

// EJS
app.set('view engine', 'ejs');

// Bodyparser
app.use(express.urlencoded({ extended: false }));

// Static Folder
app.use(express.static(path.join(__dirname, 'public')));

// Method Override
app.use(methodOverride('_method'));

// Express Session
app.use(session({
  secret: 'secret',
  resave: true,
  saveUninitialized: true,
}));

// Passport Middleware
app.use(passport.initialize());
app.use(passport.session());

// Connect Flash
app.use(flash());

// Global Variables for Flash Messages
app.use(function (req, res, next) {
  res.locals.success_msg = req.flash('success_msg');
  res.locals.error_msg = req.flash('error_msg');
  res.locals.error = req.flash('error');
  next();
});

// Routes
app.use('/', require('./routes/index'));
app.use('/users', require('./routes/users'));
app.use('/habits', require('./routes/habits'));

const PORT = process.env.PORT || 5000;

app.listen(PORT, console.log(`Server started on port ${PORT}`));
5. Configure Passport.js for Authentication
Create a passport.js file in the config directory:


// config/passport.js
const LocalStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');
const bcrypt = require('bcryptjs');

// Load User Model
const User = require('../models/User');

module.exports = function (passport) {
  passport.use(
    new LocalStrategy({ usernameField: 'email' }, (email, password, done) => {
      // Match User
      User.findOne({ email: email })
        .then(user => {
          if (!user) {
            return done(null, false, { message: 'That email is not registered' });
          }

          // Match Password
          bcrypt.compare(password, user.password, (err, isMatch) => {
            if (err) throw err;

            if (isMatch) {
              return done(null, user);
            }
            else {
              return done(null, false, { message: 'Password incorrect' });
            }
          });
        })
        .catch(err => console.log(err));
    })
  );

  // Passport Serialization
  passport.serializeUser((user, done) => {
    done(null, user.id);
  });

  // Passport Deserialization
  passport.deserializeUser((id, done) => {
    User.findById(id).populate('habits').exec((err, user) => {
      done(err, user);
    });
  });
};
6. Create User and Habit Models
User Model (models/User.js):


// models/User.js
const mongoose = require('mongoose');

const UserSchema = new mongoose.Schema({
  name: { type: String, required: true },
  email: { type: String, required: true, unique: true },
  password: { type: String, required: true },
  date: { type: Date, default: Date.now },
  habits: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Habit' }]
});

const User = mongoose.model('User', UserSchema);

module.exports = User;
Habit Model (models/Habit.js):


// models/Habit.js
const mongoose = require('mongoose');

const HabitSchema = new mongoose.Schema({
  name: { type: String, required: true },
  streak: { type: Number, default: 0 },
  images: [{ type: String }],
  user: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
  date: { type: Date, default: Date.now }
});

const Habit = mongoose.model('Habit', HabitSchema);

module.exports = Habit;
7. Authentication Routes (routes/users.js)

// routes/users.js
const express = require('express');
const router = express.Router();
const bcrypt = require('bcryptjs');
const passport = require('passport');

// Load User Model
const User = require('../models/User');
const Habit = require('../models/Habit');

// Login Page
router.get('/login', (req, res) => res.render('users/login'));

// Register Page
router.get('/register', (req, res) => res.render('users/register'));

// Register Handle
router.post('/register', (req, res) => {
  const { name, email, password, password2 } = req.body;
  let errors = [];

  // Validation checks (you can add more)

  if (password !== password2) {
    errors.push({ msg: 'Passwords do not match' });
  }

  if (errors.length > 0) {
    res.render('users/register', { errors, name, email, password, password2 });
  }
  else {
    // Validation passed
    User.findOne({ email: email })
      .then(user => {
        if (user) {
          // User exists
          errors.push({ msg: 'Email is already registered' });
          res.render('users/register', { errors, name, email, password, password2 });
        }
        else {
          const newUser = new User({ name, email, password });

          // Hash Password
          bcrypt.genSalt(10, (err, salt) =>
            bcrypt.hash(newUser.password, salt, async (err, hash) => {
              if (err) throw err;

              // Set password to hashed
              newUser.password = hash;

              // Save user
              await newUser.save();

              // Assign default habits
              const defaultHabits = ['Exercise', 'Read', 'Meditate'];
              for (let habitName of defaultHabits) {
                let habit = new Habit({ name: habitName, user: newUser._id });
                await habit.save();
                newUser.habits.push(habit);
              }

              await newUser.save();

              req.flash('success_msg', 'You are now registered and can log in');
              res.redirect('/users/login');
            })
          );
        }
      });
  }
});

// Login Handle
router.post('/login', (req, res, next) => {
  passport.authenticate('local', {
    successRedirect: '/dashboard',
    failureRedirect: '/users/login',
    failureFlash: true
  })(req, res, next);
});

// Logout Handle
router.get('/logout', (req, res) => {
  req.logout(() => {
    req.flash('success_msg', 'You are logged out');
    res.redirect('/users/login');
  });
});

module.exports = router;
8. Habit Routes (routes/habits.js)

// routes/habits.js
const express = require('express');
const router = express.Router();
const { ensureAuthenticated } = require('../helpers/auth');
const multer = require('multer');
const path = require('path');

// Load Habit Model
const Habit = require('../models/Habit');

// Set Storage Engine for Multer
const storage = multer.diskStorage({
  destination: './public/uploads/',
  filename: function (req, file, cb) {
    cb(null, req.user.id + '-' + Date.now() + path.extname(file.originalname));
  }
});

// Init Upload
const upload = multer({ storage: storage });

// Add Habit Form
router.get('/add', ensureAuthenticated, (req, res) => {
  res.render('habits/add');
});

// Process Add Habit Form
router.post('/add', ensureAuthenticated, async (req, res) => {
  const { name } = req.body;
  let errors = [];

  if (!name) {
    errors.push({ msg: 'Please enter a habit name' });
  }

  if (errors.length > 0) {
    res.render('habits/add', { errors, name });
  }
  else {
    const newHabit = new Habit({
      name,
      user: req.user.id
    });

    await newHabit.save();

    req.user.habits.push(newHabit);
    await req.user.save();

    req.flash('success_msg', 'Habit added');
    res.redirect('/dashboard');
  }
});

// Show Habit
router.get('/:id', ensureAuthenticated, async (req, res) => {
  const habit = await Habit.findById(req.params.id).populate('user');
  res.render('habits/show', { habit });
});

// Upload Image for Habit
router.post('/upload/:id', ensureAuthenticated, upload.single('image'), async (req, res) => {
  const habit = await Habit.findById(req.params.id);
  if (habit.user.toString() !== req.user.id.toString()) {
    req.flash('error_msg', 'Not Authorized');
    return res.redirect('/dashboard');
  }

  habit.images.push(`/uploads/${req.file.filename}`);
  habit.streak += 1; // Increment streak
  await habit.save();

  req.flash('success_msg', 'Image uploaded and streak updated');
  res.redirect(`/habits/${req.params.id}`);
});

module.exports = router;
9. Index Route and Dashboard (routes/index.js)

// routes/index.js
const express = require('express');
const router = express.Router();
const { ensureAuthenticated } = require('../helpers/auth');

// Welcome Page
router.get('/', (req, res) => res.render('index'));

// Dashboard
router.get('/dashboard', ensureAuthenticated, (req, res) => {
  res.render('dashboard', {
    user: req.user
  });
});

module.exports = router;
10. Authentication Middleware (helpers/auth.js)
Create a new directory helpers and a file auth.js:


// helpers/auth.js
module.exports = {
  ensureAuthenticated: function (req, res, next) {
    if (req.isAuthenticated()) {
      return next();
    }
    req.flash('error_msg', 'Please log in to view that resource');
    res.redirect('/users/login');
  }
};
11. Create Views

12. Add CSS Styling (Optional)
You can add custom CSS in public/css/style.css or use Bootstrap classes for styling.

13. Running the Application
Start the server using:


node app.js
Visit http://localhost:5000 in your browser to see the application.

Notes and Next Steps
User Interaction: Users can view other users' habits by implementing additional routes and views to display profiles and habit progress.
Social Features: Implement features like commenting, liking habits, and following users to enhance the social media aspect.
Input Validation: Use validation libraries like express-validator to ensure data integrity.
Security Improvements: Implement measures like rate limiting, sanitizing inputs to prevent injection attacks, and HTTPS for secure data transmission.
Deploying the App: Consider deploying your app using platforms like Heroku, AWS, or DigitalOcean.
Front-end Frameworks: For a more dynamic front-end, integrate React, Vue.js, or Angular. ---- use suoabase isnetad of mongodb --also use --- less files --make simple to copy and implement -- no authentication required - it's ip based
