Missing error handling middleware for asyncHandler

Author: Aanand-codeCreated Aug 25, 2025Updated Aug 25, 2025

Bug Report

The asyncHandler correctly catches errors and calls next(error), but there's no error handling middleware to actually send the response to the client.

✅ Solution Needed

Add an error handling middleware that:

Catches errors passed to next(error)
Sends properly formatted error responses

Code Suggestion

Create middleware/errorMiddleware.js:

javascript

const errorHandler = (err, req, res, next) => {
    const statusCode = err.statusCode || 500
    const message = err.message || "Internal Server Error"
    
    res.status(statusCode).json({
        success: false,
        message: message,
        ...(process.env.NODE_ENV === 'development' && { stack: err.stack })
    })
}

export { errorHandler }
