🚀 Introducing error-express: Your Ultimate Error Handling Solution for Express Applications! 🚀

Are you tired of messy error handling in your Express apps? Say goodbye to confusion and frustration with error-express, a powerful NPM package designed to streamline error management in your Express applications.

🚀 Exciting News for Express Developers! 🚀

I’m thrilled to introduce error-express, a powerful NPM package that revolutionizes error handling in your Express applications! 🌟

Are you tired of cluttered error management and want a simple yet effective way to handle errors? Look no further! Here’s why you should try error-express:

🔑 Key Features:

• Easy Installation: Just run npm install error-express to get started in no time!
• Global Error Handling: Use the built-in globalErrorHandler middleware to efficiently manage errors across your app, ensuring a smooth user experience.
• Custom Error Creation: Throw custom errors with user-friendly messages and appropriate HTTP status codes using the ServerError class.
• Extendable CustomError Class: Create your own custom error types and ensure consistent error responses that fit your application's needs.
• Structured Error Serialization: The serializeErrors() method helps serialize error details for consistent and meaningful responses.

🌟 Steps:

1. Simple Installation
   Get started in a breeze! Just run:

   1npm install error-express

   1yarn add error-express

   1pnpm add error-express

   1bun add error-express

2. Global Error Handling
   Use the built-in globalErrorHandler middleware to efficiently catch and respond to errors across your application:

   1const { globalErrorHandler } = require("error-express");
   2app.use(globalErrorHandler);

3. Custom Error Creation
   Easily throw custom errors using the ServerError class, allowing for better error messaging and HTTP status handling:

   1next(new ServerError("This is a custom server error", 500));

4. Abstract CustomError Class
   Extend the CustomError class to implement your own custom error types, ensuring consistent error responses:

   1class MyCustomError extends CustomError {
   2  serializeErrors() {
   3    return { message: this.message, status: this.statusCode };
   4  }
   5}

5. Comprehensive Serialization
   The serializeErrors() method provides a structured representation of your errors, making it easy to handle responses.

📚 Usage Example:

🌟 CommonJS Syntax (CJS)

If you’re using CommonJS (the default in Node.js), here’s how to set up error-express in your app:

1const express = require("express");
2const { globalErrorHandler, ServerError } = require("error-express");
3
4const app = express();
5
6// Your routes here
7app.get("/error", (req, res, next) => {
8  next(new ServerError("This is a custom server error", 500));
9});
10
11// Example of throwing a custom error
12app.get("/some-route", (req, res) => {
13  throw new ServerError("Something went wrong!", 400);
14});
15
16// Error handling middleware
17app.use(globalErrorHandler);
18
19app.listen(3000, () => {
20  console.log("Server is running on port 3000");
21});

🌟 ES6 Module Syntax (ESM)

If you prefer using ES6 modules, your setup would look like this:

1import express from "express";
2import { globalErrorHandler, ServerError } from "error-express";
3
4const app = express();
5
6// Your routes here
7app.get("/error", (req, res, next) => {
8  next(new ServerError("This is a custom server error", 500));
9});
10
11// Example of throwing a custom error
12app.get("/some-route", (req, res) => {
13  throw new ServerError("Something went wrong!", 400);
14});
15
16// Error handling middleware
17app.use(globalErrorHandler);
18
19app.listen(3000, () => {
20  console.log("Server is running on port 3000");
21});

⚠️ Throwing Custom Errors:

You can throw custom errors using the ServerError class:

1import { ServerError } from "error-express";
2
3app.get("/error", (req, res, next) => {
4  next(new ServerError("This is a custom server error", 500));
5});
6
7// Example of throwing a custom error
8app.get("/some-route", (req, res) => {
9  throw new ServerError("Something went wrong!", 400);
10});
