🎭 Grouping

Paths

Like Routing, groups can also have paths that belong to a cluster.

func main() {
app := fiber.New()
api := app.Group("/api", middleware) // /api
v1 := api.Group("/v1", middleware) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
v2 := api.Group("/v2", middleware) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
app.Listen(3000)
}

A Group of paths can have an optional handler.

func main() {
app := fiber.New()
api := app.Group("/api") // /api
v1 := api.Group("/v1") // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
v2 := api.Group("/v2") // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
app.Listen(3000)
}

Running /api, /v1 or /v2 will result in 404 error, make sure you have the errors set.

Group Handlers

Group handlers can also be used as a routing path but they must have Next added to them so that the flow can continue.

func main() {
app := fiber.New()
api := app.Group("/api") // /api
v1 := api.Group("/v1", func(c *fiber.Ctx) error {
c.JSON(fiber.Map{
"message": "v1",
})
return c.Next()
}) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
app.Listen(3000)
}
