Keep only what the project uses
Unused files, abandoned integrations and unnecessary packages make a codebase harder to understand. A dependency should have a clear purpose. Removing obsolete parts reduces the amount of code a maintainer has to review, although it does not replace security testing or regular updates.
Review changes before publishing
Dependency updates should be accompanied by a build and checks of the features they can affect. A successful package installation only tells us that installation worked. Navigation, forms and content still need review in the application. A small, repeatable verification routine makes future updates easier to handle.
Be precise about the limits
An automated audit reports what it can detect at a particular moment. It cannot promise that a website will never have a vulnerability. Clear documentation records the checks performed, the remaining responsibilities and the steps needed to keep the project up to date.
