Go Limit

Rate limit for Go

Usage

limit := golimit.NewLimiter(3 * time.Minute, 35) // Maximum 35 events for 3 minutes

if limit.IsBanned("user string identifier") {
    w.WriteHeader(http.StatusTooManyRequests)
    w.Write([]byte("429 - Too many requests"))
    return
}

if limit.Allow("user string identifier") == false {
    // User has reached its quota

    limit.Ban("user string identifier", 60 * time.Second) // You can also ban user
}

// Group limits
group := golimit.NewGroupLimiter(
    golimit.NewLimiter(1*time.Second, 2),
    golimit.NewLimiter(1*time.Minute, 30),
)
    
group.Allow("id")
group.Ban("id", 60 * time.Second)
group.IsBanned("id")

// Banned users count
lim.BannedCount()
group.BannedCount()
