Async Error Handling Middleware for Express with ESM Support

This middleware helps you eliminate the need for ```try-catch``` blocks throughout your Express application, streamlining error handling and improving code readability.

> **Note** : This is made specifically for ExpressJS projects.

## Usage

To use ```node-async-handler```, simply wrap your async functions in the asyncHandler middleware:

```ts

// For ESM

import pkg from 'node-async-handler';

const { asyncHandler } = pkg;

// For CommonJS

const { asyncHandler } = require('node-async-handler');

express.get('/', asyncHandler(async (req: Request, res: Response, next: NextFunction) => {

  const result = await someAsyncFunction();

  res.json(result);

}));

```

In case of an error, the middleware automatically calls ```next(error)```, allowing centralized error handling in your Express app.

## Importing

> **Note** : To import ```node-async-handler``` in ESM:

> const { asyncHandler } = pkg;
