assemble-handle

Assemble pipeline plugin for handling custom middleware stages in the Assemble build system. Version 1.0.0 is the latest stable release, updated on npm with monthly downloads. It allows you to create and manage middleware stages like 'onStream', 'preWrite', and 'postWrite', and handle them on files via .pipe(). The package also provides a .once() method to prevent middleware from running multiple times for the same stage. Key differentiator: tightly integrated with Assemble, not a general-purpose middleware runner.
