🤗 [Question]: 🚨 Which context to use for request cancellation?

[abanoub-fathy]

Question Description

Problem:
When a user cancels the request (e.g., closes browser tab), processing continues. I need it to stop immediately.

What I tried:

• c.Context() ❌ Not working
• c.UserContext() ❌ Not working

Question:
Which context should I use to properly cancel downstream processing (service → repo → DB) when the request is cancelled?

func (h *MovieHandler) getMovies(c *fiber.Ctx) error {
    // Which context to use here? 🤔
    ctx := c.Context() // This doesn't seem to work
    
    filter := parseFilter(c)
    movies, err := h.moviesService.GetMovies(ctx, filter)
    if err != nil {
        return c.Status(fiber.StatusInternalServerError).JSON(err)
    }
    
    return c.JSON(movies)
}

Expected Behavior:
When user cancels request → all processing stops immediately ⚡

Thanks for your help! 🙌

think the request cancelation should run in one of the versions
fasthttp 1.56.0 - 1.57.0
unfortunately we did not pack them in version 2, because the old go version is deprecated
