Libexpress NPM

Express-TS Decorators

A lightweight and modern decorator library for Express.js written in TypeScript. This library simplifies route definitions, middleware application, and error handling by leveraging the latest ECMAScript decorators (TypeScript 5+).

Features

🚀 Route Handlers: Define routes declaratively using @Route decorators.
🛡️ Middleware Support: Attach middleware to specific routes with @Middleware.
❌ Error Handlers: Handle errors elegantly with @ErrorHandler.
🗂️ Controller Organization: Group related routes with @Controller.
🌐 Extensibility: Easily extendable for custom use cases.

Getting Started

Installation

Install the library using npm or yarn:

npm install libexpress

yarn add libexpress

Usage

1. Create a Controller

import { Route, Middleware, Controller } from "libexpress";

@Controller("/api/users")
class UserController {
  @Get("/")
  getAllUsers(req, res) {
    res.send("List of users");
  }

  @Middleware(authMiddleware)
  @Post("/create")
  createUser(req, res) {
    res.send("User created");
  }
}

2. Register Controllers

import express from "express";
import { registerControllers } from "libexpress";
import { UserController } from "./controllers/UserController";

const app = express();
app.use(express.json());

registerControllers(app, [UserController]);

app.listen(3000, () => {
  console.log("Server running on http://localhost:3000");
});
