Npm-Package-Protected-routes

This npm package provides middleware for protecting routes in a backend application using JSON Web Tokens (JWT). It verifies the presence and validity of a JWT token from the client's cookies, retrieves the user ID, and fetches user details from a specified user model. If successful, it attaches the user object to the request (req.user) for subsequent route handling. Handles various error scenarios like missing or invalid tokens, unauthorized access, and internal server errors.

Installation

Install the package via npm:

npm install protected-mid


Usage

import ProtectedApp from "protected-mid"
import userModel from "../models/userModel.js"


Setting Up

Define options for ProtectedApp:

const options ={
    secret:process.env.JWT,  jwt secret key
    tokenName:'token',    name of token which you stored in cookies
    getUserId:(decodedToken)=>decodedToken.userId,   pass id or userId which you used to generate jwt token 
    userModel:userModel  pass userModel here to get login user  }


Using Middleware

Apply ProtectedApp middleware to protect your routes: 


// Example route protected by the middleware

router.get('/getuser', ProtectedApp(options), controller )
