Documentation

In first step we have to install library which I have given above. Second step in our API is login page when you have account, but if no you have to go to register page where you can create your account. When you are in admin group you have access into user nad user/:id pages (Currently group can change in MongoDB Compass, but I work on this).

Code

Login

Here I paste piece of code from login file. This code get data (email, password) from body nad find user with this email. When found someone with this email, compare passwords from db and from body, when compare return true. After whole security we are createing auth_token to check user for is login, and save this in session. In session we are also saveing group of user to until later validation on others pages.

//parser from form
const urlencodedParser = bodyParser.urlencoded({ extended: false });


router.post('/', urlencodedParser, (req, res) => {
    // First Validate The Request
    const { error } = validate(req.body);
    if (error) {
        return res.status(400).send(error.details[0].message);
    }

    (async() => {
        const user = await User.findOne({ email: req.body.email });
        if(user) {
            //check passwowrd
            bcrypt.compare(req.body.password, user.password, function(err, result) {
                if(result == true) {
                    //generate token
                    const token = crypto.randomBytes(28).toString('hex');
    
                    req.session.token = token;
                    req.session.name = user.name;
    
                    return res.redirect(301, '/home');
                }
                else {
                    return res.send('Whats is wrong');
                }
            });
        }
        else {
            return res.send("User deosnt exist");
        }
    })();
});

module.exports = router;

Fetch all active session on server

const session = require('express-session');

// Use the session middleware
app.use(session({
  secret: 'abc123',
  resave: false,
  saveUninitialized: true,
}));

app.get('/sessions', (req, res) => {
  // Get all the sessions that are currently stored
  const sessions = session.all;

  res.send(sessions);
});

To do

• Find solution to get all Sessions from store
• Create frontend for to login and home pages
• Page with single article article/:id
