Making a Web Application Robust
Explore techniques to make Go web applications resilient by implementing centralized panic recovery using closures and deferred functions. Understand how to avoid code duplication while ensuring your server stays operational even when handler functions encounter runtime errors. This lesson prepares you to build dependable web servers that gracefully handle unexpected failures.
We'll cover the following...
When a handler function in a web application panics our web server simply terminates. This is not good: a web server must be a robust application, able to withstand what perhaps is a temporary problem.
A first idea could be to use defer/recover in every handler-function, but this would lead to much duplication of code. Applying the error-handling scheme with closures is a much more elegant solution. Here, we show this mechanism ...
