Code refactoring - reusing a common handler in multiple crawlers while keeping code hints

The community member has a code snippet with a router.addHandler function that they want to reuse across multiple crawlers. They are unsure if there is a better way to do this without losing code hints and linting features. The comments suggest that splitting the routes into separate files may be a solution, as mentioned in the Crawlee documentation. However, some community members express frustration that this is not a straightforward solution and can lead to "hacky" code. There is a discussion around using TypeScript to define a "handler function" type, but it is unclear if this would fully address the issue. One community member suggests importing the label and handler function from a separate file, but others note that this can still cause problems with linting and dev tool functionality. There is no explicitly marked answer in the comments.
