(speedbump 
A Redis-backed Rate Limiter for Go
Cool stuff
- Backed by Redis, so it keeps track of requests across a cluster
- Extensible timing functions. Includes defaults for tracking requests per
second, minute, and hour - Works with IPv4, IPv6, or any other unique identifier
- Example middleware included for Gin (See: ginbump) and
Negroni (See:
negronibump)
Versions, Branch, Go Get Command, Client Version, -, ---, ---, ---, ---, v2, go get gopkg.in/etcinit/speedbump.v2, gopkg.in/redis.v5, Link, v1, master, go get gopkg.in/etcinit/speedbump.v1, gopkg.in/redis.v3, Link, v0, go get gopkg.in/etcinit/speedbump.v0, gopkg.in/redis.v2, Link, ## Usage
- Get a working Redis server
- Go get:
$ go get github.com/etcinit/speedbump
- Include it in your code
package main
import (
"fmt"
"time"
"github.com/etcinit/speedbump"
"gopkg.in/redis.v5"
)
func main() {
client := redis.NewClient(&redis.Options{
Addr: "localhost:6379",
Password: "",
DB: 0,
})
hasher := speedbump.PerSecondHasher{}
// Here we create a limiter that will only allow 5 requests per second
limiter := speedbump.NewLimiter(client, hasher, 5)
for {
// This example has a hardcoded IP, but you would replace it with the IP
// of a client on a real case.
success, err := limiter.Attempt("127.0.0.1")
if err != nil {
panic(err)
}
if success {
fmt.Println("Successful!")
} else {
fmt.Println("Limited! :(")
}
time.Sleep(time.Millisecond * time.Duration(100))
}
}
- Output:
