type Middleware ¶

type Middleware interface {
	// Name returns the name of the middleware.
	Name() string
	// Order returns the order of the middleware. Negative orders register
	// before the route handlers and positive orders after, each sorted
	// ascending; the zero default registers in the before group.
	Order() int
	// Apply applies the middleware to the router.
	Apply(router fiber.Router)
}

Middleware is the route-assembly contract the framework applies to the HTTP router at boot. It is the extension point for anything an application needs to mount outside the /api surface — a webhook receiver, a single-sign-on gateway, a health probe — and is registered with vef.ProvideMiddleware.

The contract lives in this public package rather than beside its implementation because fx collects the middleware group by exact type: a contract an application cannot name is a contract it cannot satisfy, and the group would silently drop whatever it provided instead.
