Front End Gen Error

rarely go right all the time in the real world. Error handling is a vital part of any application's user experience, and if done well, can leave your users feeling informed and properly error handling best practices considered. Most errors that an application encounters can be grouped into a few categories:
Data Error Handling
Input Errors: Information provided by the user is unacceptable for some reason. This includes errors from form validation, duplicate actions, uniqueness issues,
Application Logging Best Practices C#
resources not found, etc. Authorization Errors: A user is attempting to perform an action to which he/she does not have permission. Availability Errors: A resource that is needed to complete the user's action is unavailable

for some reason. This may be expected (scheduled maintenance) or unexpected (server crash!). Unexpected Errors: These are errors that likely indicate a bug in the application, such as unhandled exceptions. Almost every application will have instances of each of these error categories at some point. Handling each appropriately is key to keeping users who encounter errors from becoming angry users. Front-End vs. Back-End Error Handling In web application back-ends, expected errors are what is error handling usually handled by displaying or responding with some kind of error message, while unexpected errors will short circuit the normal response process and display a generic error page. Applications that are very poorly configured might even spit out internal error details to the end user. For the most part, back-end applications are not always good at helping a user recover from an error, but they are pretty good at letting the user know something is wrong. Front-end applications, for better or worse, have no built-in mechanism for halting everything and displaying an error message. When a JavaScript error occurs, usually one of three things happens: The application keeps running, but something the user expected to happen doesn't happen. The most common user response to this type of error is simply to try the action again (and again) hoping it will "work this time." The application stops running but displays no sign that it has stopped. The user will retry the action (or try to perform a different one) to no avail. If the error happened early enough, the entire page may be prevented from being properly set up and the user will just see a white screen. These scenarios, from a user experience perspective, are terrible. They are likely to lead to user frustrati

Structured exception handling is always preferred as it is easier to cover 100% of code. On the other hand it is very hard to cover 100% of all errors in languages that do not have exceptions, such as PHP 4. Code that covers 100% of errors is extraordinarily verbose and difficult to read, and can contain subtle bugs and errors in the error handling code itself. Motivated attackers like to see error messages as they might leak information that leads to further attacks, or may leak privacy related information. Web application error handling is rarely robust enough to survive a penetratio
