Create JWT Token ( util/jwt.util.js)

• npm i jsonwebtoken

    const jwt = require('jsonwebtoken')
    const TOKEN_SECRET = "7bc78545b1a3923cc1e1e19523fd5c3f20b409509";//process.env.ACCESS_TOKEN_SECRET;

    class JwtUtil
    {
        
        static  generateAccessToken(username) {
            // expires after 60 mins (3600 seconds = 60 minutes)
            return jwt.sign({data:username}, TOKEN_SECRET, { expiresIn: 60*60 });
        }
    }

    exports.JwtUtil = JwtUtil;

Task 2: Add token in login api ( user.controller.js)

    const {JwtUtil} = require("./util/jwt.util");

      async login(req,res){
        let {email,password} = req.body;        
        const userDAO = new UserDAO();
        const users = await userDAO.login(email,password);
        if (users.length ==0){
            throw new Error("Invalid Login Credentials");
        }

        let user = users[0];
        let token = JwtUtil.generateAccessToken(user);  
        user['token'] = token; // Add token in user details 
        res.status(201).json(user);
    }
