🤔 How do I Set/Get data in context? about fiber HOT 7 CLOSED

We use Locals, for more information please visit our documentation.

func main() {
  app := fiber.New()
  app.Use("/api", func(c *fiber.Ctx) {
    c.Locals("claims", claims)
    c.Next()
  })
  app.Get("/api/v1/manager", func(c *fiber.Ctx) {
    claims := c.Locals("claims")
  })
  app.Listen(3000)
}

I am new in fiber. How can we reach claims im 4th line

func main() {
  app := fiber.New()
  app.Use("/api", func(c *fiber.Ctx) {
    c.Locals("claims", claims) --> how can we reach claims in here 
    c.Next()
  })
  app.Get("/api/v1/manager", func(c *fiber.Ctx) {
    claims := c.Locals("claims")
  })
  app.Listen(3000)
}

from fiber.

	app.Use(func() fiber.Handler {
		return func(c *fiber.Ctx) error {

			return c.Next()
		}
	}())

How can this work c.Locals get two parametr how you could give him one and publish here that this is working.

This method allows you to store and retrieve any data in the context of a request. It can accept one or two parameters, depending on whether you want to get or set a value.
The first parameter is the key, which is any type that can be used as a map key. The second parameter is optional, and it is the value that you want to associate with the key. If you omit the second parameter, the method will return the value that is stored for the key, or nil if there is none. If you provide the second parameter, the method will set the value for the key and return it.

You can see why in the current func implementation:

func (c *DefaultCtx) Locals(key any, value ...any) any {
	if len(value) == 0 {
		return c.fasthttp.UserValue(key)
	}
	c.fasthttp.SetUserValue(key, value[0])
	return value[0]
}

hope that helps.

This is an awesome feature in the Context - might want to list it as a feature elsewhere so this isn't the route to find it!
