🎭 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
log.Fatal(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
log.Fatal(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()
handler := func(c *fiber.Ctx) error {
return c.SendStatus(fiber.StatusOK)
}
api := app.Group("/api") // /api
v1 := api.Group("/v1", func(c *fiber.Ctx) error { // middleware for /api/v1
c.Set("Version", "v1")
return c.Next()
})
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
log.Fatal(app.Listen(":3000"))
}
