# nostr
A minimal Go library for the [Nostr protocol](https://github.com/nostr-protocol/nostr).
```bash
go get code.northwest.io/nostr
```
## Why This Library?
**1 dependency.** That's it.
Other Nostr libraries pull in 30+ dependencies. This one has exactly one direct dependency: `btcec` for Schnorr signatures (required by the protocol).
```
require github.com/btcsuite/btcd/btcec/v2 v2.3.4
```
No WebSocket libraries, no logging frameworks, no kitchen sink. Just the core protocol.
## What's Included
- **Keys** — Generate, parse, sign, verify (hex and bech32/npub/nsec)
- **Events** — Create, serialize, sign NIP-01 events
- **Filters** — Build and match subscription filters
- **Relay** — WebSocket pub/sub (stdlib `net/http` only)
- **Tags** — Parse and build event tags
- **Envelopes** — Protocol message parsing
## What's Not Included
This is a minimal core library. It implements NIP-01 and the basics. It doesn't implement every NIP, handle connection pooling, or manage relay discovery. Build that yourself, or don't.
## Usage
```go
package main
import (
"context"
"fmt"
"code.northwest.io/nostr"
)
func main() {
// Generate a key pair
key, _ := nostr.GenerateKey()
fmt.Println("npub:", key.Npub())
// Create and sign an event
event := &nostr.Event{
Kind: nostr.KindTextNote,
Content: "Hello Nostr!",
}
event.Sign(key)
// Connect and publish
ctx := context.Background()
relay, _ := nostr.Connect(ctx, "wss://relay.damus.io")
defer relay.Close()
relay.Publish(ctx, event)
}
```
