quickstruc is a Node.js-powered module designed to streamline project scaffolding.

class AppError extends Error {
  public statusCode: number;
  public isOperational: boolean;
  public status: string;

  constructor(
    message: string,
    statusCode: number = 500,
    status: string = "error"
  ) {
    super(message); // Call parent class constructor (Error)
    this.statusCode = statusCode; // Set status code, defaulting to 500 (Internal Server Error)
    this.isOperational = true; // Operational error flag
    Error.captureStackTrace(this, this.constructor); // Captures the stack trace for better error reporting
    this.status = status;
    // Set the name of the error to the class name (AppError)
    this.name = this.constructor.name;
  }
}

export default AppError;
