Why This Issue Is Important
In an Apigee proxy, resources such as JavaScript files, XSLT files, or other assets are typically linked to policies that use them during the API flow. If a resource is not linked to any policy, it essentially becomes dead code—present in the proxy but never executed or utilized. This can lead to a loss of intended functionality, making the proxy less reliable and potentially causing unexpected behavior. Moreover, unused resources can clutter the proxy configuration, making it harder to maintain and understand.
How This Issue Is Detected
CodeSent detects this issue by analyzing the relationship between resources and policies within the proxy.
Identify All Resources
CodeSent first gathers all the resources defined in the proxy configuration.
Check Resource Usage
The tool then checks if each resource is linked to any policy within the proxy. It looks at all the policies to see if they reference the resource either directly or indirectly.
How to Fix the Issue
If your proxy configuration includes a resource, but this resource is not linked to any policy, you have two options: remove the unused resource or link the resource to a policy. This ensures that all resources in the proxy configuration serve a purpose, reducing the risk of functionality loss and making the proxy easier to maintain.
