Optional Parameter Example

This project demonstrates how to handle optional parameters in a Go application using the Fiber framework.

Prerequisites

Ensure you have the following installed:

• Golang
• Fiber package

Setup

1. Clone the repository:

   git clone https://github.com/gofiber/recipes.git
   cd recipes/optional-parameter

2. Install dependencies:

   go get

Running the Application

1. Start the application:

   go run main.go

Example

Here is an example of how to handle optional parameters in a Fiber application:

package main

import (
    "github.com/gofiber/fiber/v2"
)

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

    app.Get("/user/:id?", func(c *fiber.Ctx) error {
        id := c.Params("id", "defaultID")
        return c.SendString("User ID: " + id)
    })

    app.Listen(":3000")
}

In this example:

• The :id? parameter in the route is optional.
• If the id parameter is not provided, it defaults to "defaultID".
