Hello @fishonamos, I would love to handle this

How I plan on tackling this issue

1. First, i Will Create a new file errors.js in the middlewarefoled

2. Then, Create the basic error class:

class AppError extends Error {
  constructor(code, message, statusCode = 500) {
    super(message);
    this.code = code;
    this.statusCode = statusCode;
  }
}

3. Add a few specific error types:

class ValidationError extends AppError {
  constructor(message) {
    super('VALIDATION_ERROR', message, 400);
  }
}

class NotFoundError extends AppError {
  constructor(message) {
    super('NOT_FOUND', message, 404);
  }
}

4. Add error handler middleware (if using Express):

const errorHandler = (err, req, res, next) => {
  if (err instanceof AppError) {
    return res.status(err.statusCode).json({
      code: err.code,
      message: err.message
    });
  }
  return res.status(500).json({
    code: 'INTERNAL_ERROR',
    message: 'An unexpected error occurred'
  });
};

Hi, I'm Josué Brenes and I'll be working on issue.
I'm Dojo Coding member.

I estimate this will take 3 day to complete.

How I plan on tackling this issue

Here’s how I would tackle this issue:

1. Create a custom error class:

   • I will develop a new class that extends the native Error class in JavaScript or TypeScript. This custom error class will have additional properties for handling specific error codes, messages, and any other relevant data needed to provide more context in error scenarios.
   • I will define useful properties such as:
     • errorCode: A specific code that identifies the error type.
     • message: A detailed message to provide more information about the error.
     • details: Any additional data (like the failed request data, or user info) that might help with debugging.

2. Integrate the custom error class within the app/server:

   • I will replace generic error handling in the relevant sections of the app/server with the new custom error class. This will ensure that the app responds with meaningful error messages and codes in different scenarios.
   • I will also add usage of this custom error class in key areas where the app handles specific error conditions (for example, failed API calls, validation errors, or database access issues).

3. Improve error message readability:

   • I will ensure that the error messages are well-structured and readable, making it easier for developers to understand and fix issues.
   • I will also provide more granular information for different error scenarios so that it becomes easier to trace back the origin of the error in logs or monitoring tools.

4. Test the custom error handling:

   • I will create unit tests to validate that the custom error class correctly captures and provides detailed information in various error scenarios.
   • I will also perform integration tests to verify that error handling across the app works as expected with the new custom error class.

5. Completion Criteria:

   • The issue will be resolved when the custom error class is successfully created and integrated within the app/server.
   • The error handling system will be updated to provide more detailed and specific error messages in the relevant parts of the app.
   • Unit and integration tests will confirm the proper functionality of the custom error handling system.

Create and Use a Custom Error Class in app/server

Hello LandVer team,

I am Joel Vargas, and I'm a member of Dojo Coding. I also come from OnlyDust.

I would like to request the assignment of this issue. Below is my proposed approach for implementing this issue:

How I plan on tackling this issue

Proposal to Develop a Custom Error Class for Improved Error Handling

Problem

Currently, the app/server may utilize generic error handling, which can lead to ambiguity and make it difficult to identify specific error scenarios. This lack of granularity can hinder debugging efforts and reduce code readability. A custom error class will allow us to handle errors more effectively and provide clearer feedback in various parts of the application.

Solution

To enhance error handling, I propose the development of a custom error class that extends the base Error class or utilizes a suitable error handling library. This custom error class will provide structured error information, improving the overall maintainability of the codebase.

Key Features

1. Custom Error Class Implementation:

   • Create a custom error class that extends the standard JavaScript Error class.
   • Include properties such as errorCode, errorMessage, and additionalData to encapsulate relevant error information.

2. Granular Error Handling:

   • Utilize the custom error class in relevant parts of the app/server to handle specific error conditions more effectively.
   • This will enable developers to catch and respond to different error scenarios with more precision.

3. Informative Error Messages:

   • Ensure that the custom error class provides informative error messages that can assist in debugging.
   • Include stack traces and contextual information as needed to help identify the source of the error.

Implementation Details

1. Custom Error Class Definition:

   • Create a new file (e.g., CustomError.js) to define the custom error class:

     class CustomError extends Error {
       constructor(errorCode, errorMessage, additionalData = null) {
         super(errorMessage);
         this.name = this.constructor.name;
         this.errorCode = errorCode;
         this.additionalData = additionalData;
         Error.captureStackTrace(this, this.constructor);
       }
     }
     
     export default CustomError;

2. Using the Custom Error Class:

   • Replace existing error handling logic with the custom error class in relevant parts of the app/server. For example:

     import CustomError from './CustomError';
     
     function someFunction() {
       try {
         // Some operation that might fail
         throw new CustomError('USER_NOT_FOUND', 'The specified user does not exist', { userId: 123 });
       } catch (error) {
         if (error instanceof CustomError) {
           console.error(`Error Code: ${error.errorCode}, Message: ${error.message}`);
         } else {
           console.error('An unexpected error occurred:', error);
         }
       }
     }

3. Testing and Validation:

   • After implementing the custom error class, conduct thorough testing to ensure it behaves as expected.
   • Create unit tests to validate that the custom error class can be instantiated correctly and provides the expected properties.

Definition of Completion

The project will be considered complete when:

• A custom error class is created, extending the base Error class or a suitable error handling library.
• The custom error class includes properties for errorCode, errorMessage, and additionalData.
• The custom error class is utilized in relevant parts of the app/server to handle specific error conditions, providing more informative error messages.
• Documentation is updated to reflect the new error handling approach.

Benefits

• Improved Code Readability: Structured error handling enhances code clarity and makes it easier for developers to understand error scenarios.
• Better Debugging Experience: Informative error messages and structured data allow for faster identification and resolution of issues.
• Consistent Error Handling: Using a custom error class ensures a uniform approach to error handling throughout the application.

Next Steps

• Implement the custom error class as proposed.
• Replace existing error handling with the new class in the relevant sections of the codebase.
• Conduct testing and gather feedback for potential improvements.

i am a cerfield full stack developer with half a decade years of experience in developing professional apps and webpages

How I plan on tackling this issue

I will approach the problem using this steps

1. Create the Custom Error Class
   I would define a custom error class to handle specific error scenarios. It will include properties for error codes, messages, and additional data, improving error clarity.

2.Integrating the Custom Error Class in the Application
In relevant parts of the app/server, I would use this custom error class to throw specific errors. For example, in routes or middleware, I would throw CustomError for cases like invalid input, unauthorized access, etc.

3. Global Error Handler
   I would implement a global error handler to catch all errors and format the response appropriately. The handler would look for CustomError instances to display meaningful messages and status codes.

Testing and Usage
Ensure the CustomError is used wherever errors are thrown in the app (e.g., API routes, services, etc.).
Test the error handling with various scenarios, such as unauthorized access, invalid inputs, or other business logic failures.
Confirm that meaningful messages and appropriate status codes are returned.

How I plan on tackling this issue

Approach for Issue #90: Create and Use a Custom Error Class in app/server

1. Design the Custom Error Class: I’ll start by creating a custom error class that extends the native Error class in JavaScript. This class will allow us to define specific error properties like error codes, messages, and additional data. I’ll ensure that it accepts parameters for these properties so that we can throw more descriptive errors throughout the app.

This is a sample of what it could look like:

class CustomError extends Error {
constructor(message, errorCode, data = null) {
super(message);
this.name = this.constructor.name;
this.errorCode = errorCode;
this.data = data;
Error.captureStackTrace(this, this.constructor);
}
}

2. Integrate the Custom Error Class: After defining the class, I’ll update relevant parts of the app/server to use it. This involves identifying key areas where specific error handling is needed, such as API calls, database operations, or external service requests. I’ll replace generic errors with instances of the custom error class, which will make debugging easier and provide more context to the errors.

This is a conceptual implementation of what it could look like.
if (!user) {
throw new CustomError("User not found", 404, { userId });
}

3. Enhance Error Handling: I’ll ensure that all places where errors are caught (e.g., middleware, controllers) are updated to handle the new custom error class. This includes logging the error code and any additional data provided to the error class. For server responses, I’ll ensure the user sees clear, helpful error messages without exposing sensitive information.

4. Testing and Validation: I’ll write test cases to validate that the custom error class works as expected. I’ll test both typical and edge cases to ensure the class captures errors correctly and that error messages are clear in various scenarios.

5. Documentation and Best Practices: I’ll document the usage of the custom error class, outlining where and how to use it in the codebase. This will help ensure that future developers follow a consistent pattern for error handling, leading to better maintainability.
