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"))
}
