Getting Started

Unified Errors Handler is an advanced error-handling library for Node.js. It standardizes error structures across Express.js, NestJS, and databases like MySQL, PostgreSQL, and MongoDB. It simplifies debugging, improves consistency, and enhances error logging.

Installation

$ npm install unified-errors-handler

Unified Structure

All errors will be mapped to this structure, and that make errors:

• Consistent Format – A clear and structured response for errors.
• Support for Multiple Errors – The array allows multiple validation errors at once.
• Extensibility – The details object lets you provide extra information.

{
   errors: [{
      fields: ['name', 'password'],   // optional
      code: 'YOUR_CODE',
      message: 'your message'
      details: {    // optional - more details about error
        key: value 
      }
   }]
}
