+# khatru, a relay framework [![docs badge](https://img.shields.io/badge/docs-reference-blue)](https://pkg.go.dev/github.com/fiatjaf/khatru#Relay)
+
+[![Run Tests](https://github.com/fiatjaf/khatru/actions/workflows/test.yml/badge.svg)](https://github.com/fiatjaf/khatru/actions/workflows/test.yml)
+[![Go Reference](https://pkg.go.dev/badge/github.com/fiatjaf/khatru.svg)](https://pkg.go.dev/github.com/fiatjaf/khatru)
+[![Go Report Card](https://goreportcard.com/badge/github.com/fiatjaf/khatru)](https://goreportcard.com/report/github.com/fiatjaf/khatru)
+
+Khatru makes it easy to write very very custom relays:
+
+  - custom event or filter acceptance policies
+  - custom `AUTH` handlers
+  - custom storage and pluggable databases
+  - custom webpages and other HTTP handlers
+
+Here's a sample:
+
+```go
+package main
+
+import (
+	"context"
+	"fmt"
+	"log"
+	"net/http"
+
+	"github.com/fiatjaf/khatru"
+	"github.com/nbd-wtf/go-nostr"
+)
+
+func main() {
+	// create the relay instance
+	relay := khatru.NewRelay()
+
+	// set up some basic properties (will be returned on the NIP-11 endpoint)
+	relay.Info.Name = "my relay"
+	relay.Info.PubKey = "79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798"
+	relay.Info.Description = "this is my custom relay"
+	relay.Info.Icon = "https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fliquipedia.net%2Fcommons%2Fimages%2F3%2F35%2FSCProbe.jpg&f=1&nofb=1&ipt=0cbbfef25bce41da63d910e86c3c343e6c3b9d63194ca9755351bb7c2efa3359&ipo=images"
+
+	// you must bring your own storage scheme -- if you want to have any
+	store := make(map[string]*nostr.Event, 120)
+
+	// set up the basic relay functions
+	relay.StoreEvent = append(relay.StoreEvent,
+		func(ctx context.Context, event *nostr.Event) error {
+			store[event.ID] = event
+			return nil
+		},
+	)
+	relay.QueryEvents = append(relay.QueryEvents,
+		func(ctx context.Context, filter nostr.Filter) (chan *nostr.Event, error) {
+			ch := make(chan *nostr.Event)
+			go func() {
+				for _, evt := range store {
+					if filter.Matches(evt) {
+						ch <- evt
+					}
+				}
+				close(ch)
+			}()
+			return ch, nil
+		},
+	)
+	relay.DeleteEvent = append(relay.DeleteEvent,
+		func(ctx context.Context, event *nostr.Event) error {
+			delete(store, event.ID)
+			return nil
+		},
+	)
+
+	// there are many other configurable things you can set
+	relay.RejectEvent = append(relay.RejectEvent,
+		func(ctx context.Context, event *nostr.Event) (reject bool, msg string) {
+			if event.PubKey == "fa984bd7dbb282f07e16e7ae87b26a2a7b9b90b7246a44771f0cf5ae58018f52" {
+				return true, "we don't allow this person to write here"
+			}
+			return false, "" // anyone else can
+		},
+	)
+	relay.OnConnect = append(relay.OnConnect,
+		func(ctx context.Context) {
+			// request NIP-42 AUTH from everybody
+			relay.RequestAuth(ctx)
+		},
+	)
+	relay.OnAuth = append(relay.OnAuth,
+		func(ctx context.Context, pubkey string) {
+			// and when they auth we just log that for nothing
+			log.Println(pubkey + " is authed!")
+		},
+	)
+	// check the docs for more goodies!
+
+	mux := relay.Router()
+	// set up other http handlers
+	mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
+		w.Header().Set("content-type", "text/html")
+		fmt.Fprintf(w, `<b>welcome</b> to my relay!`)
+	})
+
+	// start the server
+	fmt.Println("running on :3334")
+	http.ListenAndServe(":3334", relay)
+}
+```
+
+### But I don't want to write my own database!
+
+Fear no more. Using the https://github.com/fiatjaf/eventstore module you get a bunch of compatible databases out of the box and you can just plug them into your relay. For example, [sqlite](https://pkg.go.dev/github.com/fiatjaf/eventstore/sqlite3):
+
+```go
+	db := sqlite3.SQLite3Backend{DatabaseURL: "/tmp/khatru-sqlite-tmp"}
+	if err := db.Init(); err != nil {
+		panic(err)
+	}
+
+	relay.StoreEvent = append(relay.StoreEvent, db.SaveEvent)
+	relay.QueryEvents = append(relay.QueryEvents, db.QueryEvents)
+	relay.CountEvents = append(relay.CountEvents, db.CountEvents)
+	relay.DeleteEvent = append(relay.DeleteEvent, db.DeleteEvent)
+```
