One post tagged with "compatibility"

One of the most underrated improvements in the v3 router is not a new method or fancy syntax. It is handler compatibility.

In plain terms: Fiber can now accept multiple handler styles directly, and the router compatibility layer adapts them for you. That sounds small until you are migrating a real codebase with hundreds of handlers, middleware functions, and utility packages in different styles. Then it becomes the feature that decides whether migration happens this quarter or gets postponed again.
