Skip

Skip middleware for Fiber that skips a wrapped handler when a predicate evaluates to true for the current request.

Signatures

func New(handler fiber.Handler, exclude func(c fiber.Ctx) bool) fiber.Handler

Examples

Import the middleware package that is part of the Fiber web framework

import (
    "github.com/gofiber/fiber/v3"
    "github.com/gofiber/fiber/v3/middleware/skip"
)

skip.New expects the handler to wrap and a predicate function. The predicate is called for every request, and returning true will bypass the wrapped handler and execute the next middleware in the chain.

After you initialize your Fiber app, you can use skip.New like this:

func main() {
    app := fiber.New()

    app.Use(skip.New(BasicHandler, func(ctx fiber.Ctx) bool {
        return ctx.Method() == fiber.MethodGet
    }))

    app.Get("/", func(ctx fiber.Ctx) error {
        return ctx.SendString("It was a GET request!")
    })

    log.Fatal(app.Listen(":3000"))
}

func BasicHandler(ctx fiber.Ctx) error {
    return ctx.SendString("It was not a GET request!")
}

tip

app.Use will handle requests from any route, and any method. In the example above, it will only skip if the method is GET.
