In this project, I implemented several custom messages to enhance the user experience, ensuring that feedback is clear and consistent throughout the application. These messages provide important notifications, guide users through operations, and handle errors gracefully. Here are the types of custom messages implemented:

1. Success Message

The success message is displayed when an operation or task is completed successfully. It provides positive feedback to the user, confirming that their action has been processed as expected.

2. Error Message

The error message is used to notify users about any issues or exceptions that occur during the execution of a command or process. It helps in identifying what went wrong and how the issue can be addressed.

3. Invalid Message

This message is shown when the user provides input that is not valid. It ensures that users are informed when they make an invalid selection or provide incorrect data.

4. Token Error Message

In case of issues related to token authentication (such as an invalid or expired token), this message is triggered to inform the user of the authentication problem.

5. Does Not Exist Message

This message appears when the user attempts to access or interact with an entity (such as a client, contract, or employee) that does not exist in the system. It helps guide users by clearly stating that the requested resource is unavailable.

6. Permission Denied Message

The permission denied message is displayed when a user attempts to perform an action for which they do not have the necessary permissions. It prevents unauthorized access to restricted functionalities.

7. Info Message

The info message provides general information or updates to the user about the current state or process. It is typically used to inform the user about progress or non-critical details.

Summary

By creating these custom messages, I aimed to provide clear, consistent, and meaningful feedback to users. These messages help improve the user interface and experience, making it easier for users to navigate the system, understand what is happening, and resolve any issues they may encounter. Each message type is tailored to a specific scenario, ensuring that the right information is communicated effectively.
