  5. Add a Procfile to the project directory with the following content:

    web: go run main.go

  6. Deploy the application to Heroku:

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

    app.Get("/", func(c *fiber.Ctx) error {
        return c.SendString("Hello, Heroku!")
    })

    log.Fatal(app.Listen(":" + getPort()))
}

func getPort() string {
    port := os.Getenv("PORT")
    if port == "" {
        port = "3000"
    }
    return port
}
