<h1>nostr</h1>
<p class="tagline">A minimal Go library for the Nostr protocol.</p>
<div class="install">go get code.northwest.io/nostr</div>
<h2>Why</h2>
<p><strong>1 dependency.</strong> Other Nostr libraries pull in 30+. This one has exactly one:</p>
<div class="dep">btcec/v2 — Schnorr signatures (required by protocol)</div>
<p>No WebSocket libraries, no logging frameworks, no kitchen sink. Just the core protocol, stdlib only.</p>
<h2>What's Included</h2>
<ul>
<li><strong>Keys</strong> — generate, parse, sign, verify (hex + bech32)</li>
<li><strong>Events</strong> — create, serialize, sign NIP-01 events</li>
<li><strong>Filters</strong> — build and match subscription filters</li>
<li><strong>Relay</strong> — WebSocket pub/sub (stdlib net/http)</li>
<li><strong>Tags</strong> — parse and build event tags</li>
<li><strong>Envelopes</strong> — protocol message parsing</li>
</ul>
<h2>Example</h2>
<pre><code>key, _ := nostr.GenerateKey()
fmt.Println("npub:", key.Npub())
event := &nostr.Event{
Kind: nostr.KindTextNote,
Content: "Hello Nostr!",
}
key.Sign(event)
relay, _ := nostr.Connect(ctx, "wss://relay.damus.io")
relay.Publish(ctx, event)</code></pre>
<h2>What's Not Included</h2>
<p>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.</p>
