Groups

A *zinc.Group registers routes below a prefix and runs its middleware before theirs. Create one from the app or from another group.

api := app.Group("/api", requireAPIKey)
v1 := api.Group("/v1")

v1.Get("/users/{id}", showUser) // GET /api/v1/users/{id}

Methods

Method	Purpose
Use(middleware...) *Group	Adds middleware for routes registered on this group and its subgroups
Group(prefix, middleware...) *Group	A nested group
Route(prefix, fn func(*Group), middleware...) *Group	A nested group declared in a block
Get, Post, Put, Patch, Delete, Head, Options, Connect, Trace	Routes below the prefix
Add, Match, All, Any	Routes for custom or multiple methods
Handle(spec), TryHandle(spec) error	Routes described by a RouteSpec
HandleHTTP(pattern, http.Handler)	A standard handler below the prefix
Mount(prefix, http.Handler)	A handler that owns a subtree below the prefix
Static, StaticFS, File, FileFS	Files below the prefix
RouteNotFound(pattern, handlers...)	A 404 handler below the prefix

The methods behave like their Application counterparts, with the group’s prefix and middleware applied.

Middleware order

Group middleware runs after app middleware and before route middleware. A nested group runs its parent’s middleware first:

api := app.Group("/api", authenticate)
admin := api.Group("/admin", requireAdmin)

admin.Delete("/users/{id}", audit, deleteUser)
// authenticate → requireAdmin → audit → deleteUser

Group middleware runs only when one of the group’s routes matches. Use app.UsePrefix for middleware that must also run for unmatched paths under a prefix.
