Jetend simplifies backend development with one-liner utilities for routing, database operations (SQL + MongoDB), authentication, validation, responses, and email sending. Think of it as a toolbox for Express developers who want to move fast without reinventing the wheel.

✨ Features

• ⚡ Minimal routing (get, post, patch, del)
• 🌱 Start a server with one line (start(port))
• 🗄️ Database utilities for SQL and MongoDB
• 🔐 Authentication helpers (bcrypt + JWT)
• ✅ Request validation with simple rules
• 📦 Consistent success/error responses
• 📧 Built-in email sending (Gmail SMTP ready)
• 🔌 Works seamlessly with Express.js

📦 Installation

npm install jetend

🚀 Quick Start

import { get, post, start } from "jetend";

// Basic routing
get("/hello", ({ res }) => {
  res.json({ message: "Hello from Jetend 🚀" });
});

post("/data", ({ req, res }) => {
  res.status(201).json(req.body);
});

// Start the server
start(3000);
// 🚀 Jetend server running at http://localhost:3000

Run your server with Express, and Jetend plugs right in.

📚 Usage Guide

1. Starting the Server

You can quickly spin up a local server using the start(port) method. Simply pass the desired port number to start listening for incoming requests.

import { start } from "jetend";

const PORT = 3000;
start(PORT); // 🚀 Jetend server running at http://localhost:3000

2. Routing

import { get, post, patch, del } from "jetend";

get("/users", ({ res }) => res.json(users));
post("/users", ({ req, res }) => res.status(201).json(req.body));
patch("/users/:id", ({ req, res }) => res.json({ updated: req.params.id }));
del("/users/:id", ({ req, res }) => res.json({ deleted: req.params.id }));

3. Database

SQL

import db from "jetend";

await db.sql.connect({
  host: "localhost",
  user: "root",
  database: "test",
  password: "1234",
});

const users = await db.sql.query("SELECT * FROM users");

MongoDB

await db.mongo.connect("mongodb://127.0.0.1:27017/test");

const User = db.mongo.model("User", { name: String, email: String });

// CRUD
await db.mongo.create(User, { name: "Alice" });
await db.mongo.read(User, { name: "Alice" });
await db.mongo.update(User, { _id }, { email: "[email protected]" });
await db.mongo.delete(User, { _id });

4. Authentication

import {
  hashPassword,
  comparePassword,
  generateJWT,
  requireAuth,
} from "jetend";

const JWT_SECRET = process.env.JWT_SECRET || "supersecret";

// Signup
const passwordHash = await hashPassword("mypassword");
await db.mongo.create(User, { username, password: passwordHash });

// Login
const ok = await comparePassword(password, user.password);
if (!ok) return error(res, "Invalid credentials", 401);

const token = generateJWT({ id: user._id }, JWT_SECRET, { expiresIn: "2h" });
res.json({ token });

// Protected Route
get("/me", requireAuth(JWT_SECRET), ({ req, res }) => {
  res.json({ user: req.user });
});

5. Validation

import { validate } from "jetend";

validate(req.body, {
  name: "string|required|min:3|max:10",
  email: "email|required",
  password: "string|min:8",
});

6. Responses

import { success, error } from "jetend";

return success(res, "User created", user, 201);
return error(res, "User not found", 404);

7. Email Sending

import { sendEmail } from "jetend";

await sendEmail(
  process.env.EMAIL, // sender
  process.env.APP_PASSWORD, // app password
  "[email protected]",
  "Welcome to Jetend 🚀",
  "<h1>Hello World</h1>",
);
