npm i nodejs-utility-package

Features

1. JWT Authentication Utilities

Configure and use JWT for authentication:

const { jwtAuthUtils } = require("nodejs-utility-package");

const jwtAuth = new jwtAuthUtils();
jwtAuth.config("your_secret_key", "24h");

const token = jwtAuth.setUser({ name: "User" });
console.log(token);

try {
    const user = jwtAuth.getUser(token);
    console.log(user);
} catch (error) {
    console.log("Token expired or invalid.");
}

Middleware for route protection:

const express = require("express");
const app = express();
const router = express.Router();

router.post(
    "/isLoggedIn",
    jwtAuth.restrictToLoggedInUserOnly,
    (req, res) => {
        res.json("User is logged in.");
    }
);

app.use("/api", router);
app.listen(8000, () => console.log("Server running on port 8000"));

Validate email addresses:

const { validationUtils } = require("nodejs-utility-package");
