What Is Gauze

Creating the Styles

Create the styles.css file in the public directory with the following content:

body {
  font-family: Arial, sans-serif;
  margin: 0;
  padding: 0;
  background-color: #f4f4f4;
}

h1 {
  text-align: center;
  margin-top: 20px;
}

form {
  text-align: center;
  margin-top: 20px;
}

input[type=“text”] {
  padding: 10px;
  font-size: 16px;
}

button {
  padding: 10px 20px;
  font-size: 16px;
  margin-left: 10px;
}

ul {
  list-style-type: none;
  padding: 0;
  text-align: center;
}

li {
  background-color: #fff;
  margin: 10px 0;
  padding: 10px;
  border-radius: 5px;
  display: inline-block;
}

a {
  text-decoration: none;
  color: red;
  margin-right: 10px;
}

Creating the Server

Create the index.js file in the root directory with the following content:

const gauze = require(‘gauze’);
const app = gauze();
const bodyParser = require(‘body-parser’);

app.set(‘view engine’, ‘ejs’);
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static(‘public’));

let tasks = [];

app.get(‘/’, (req, res) => {
  res.render(‘index’, { tasks });
});

app.post(‘/add’, (req, res) => {
  const task = { id: Date.now(), text: req.body.task };
  tasks.push(task);
  res.redirect(‘/’);
});

app.get(‘/delete/:id’, (req, res) => {
  tasks = tasks.filter(task => task.id != req.params.id);
  res.redirect(‘/’);
});

app.listen(3000, () => {
  console.log(‘To-Do List app listening on port 3000’);
});

Advanced Features of Gauze

Gauze offers several advanced features that can help you build more complex and feature-rich applications. Some of these features include:

Database Integration

Gauze can be easily integrated with various databases, such as MongoDB, MySQL, and PostgreSQL. This allows you to store and retrieve data efficiently. Here is an example of integrating MongoDB with Gauze:

const mongoose = require(‘mongoose’);

mongoose.connect(‘mongodb://localhost:27017/todoapp’, { useNewUrlParser: true, useUnifiedTopology: true });

const taskSchema = new mongoose.Schema({
  text: String
});

const Task = mongoose.model(‘Task’, taskSchema);

app.get(‘/’, async (req, res) => {
  const tasks = await Task.find();
  res.render(‘index’, { tasks });
});

app.post(‘/add’, async (req, res) => {
  const task = new Task({ text: req.body.task });
  await task.save();
  res.redirect(‘/’);
});

app.get(‘/delete/:id’, async (req, res) => {
  await Task.findByIdAndDelete(req.params.id);
  res.redirect(‘/’);
});

Authentication and Authorization

Gauze supports various authentication and authorization mechanisms, allowing you to secure your application. You can use libraries like Passport.js to implement authentication strategies such as local, OAuth, and JWT.

Here is an example of using Passport.js for local authentication:

const passport = require(‘passport’);
const LocalStrategy = require(‘passport-local’).Strategy;
const bcrypt = require(‘bcrypt’);

passport.use(new LocalStrategy(
  (username, password, done) => {
    // Implement your user lookup and password verification logic here
    // For example:
    // const user = users.find(user => user.username === username);
    // if (!user) return done(null, false, { message: ‘Incorrect username.’ });
    // if (!bcrypt.compareSync(password, user.password)) return done(null, false, { message: ‘Incorrect password.’ });
    // return done(null, user);
  }
));

app.post(‘/login’, passport.authenticate(‘local’, {
  successRedirect: ‘/’,
  failureRedirect: ‘/login’
}));

Real-Time Features

Gauze can be extended to support real-time features using WebSockets. This allows you to build applications that require real-time updates, such as chat applications or live notifications.

Here is an example of using Socket.io with Gauze:

const io = require(‘socket.io’)(server);

io.on(‘connection’, (socket) => {
  console.log(‘A user connected’);

socket.on(‘disconnect’, () => {
    console.log(‘A user disconnected’);
  });

socket.on(‘chat message’, (msg) => {
    io.emit(‘chat message’, msg);
  });
});
