Nostr SDK

Description

A high-level, Nostr client library written in Rust.

If you're writing a typical Nostr client or bot, this is likely the crate you need.

However, the crate is designed in a modular way and depends on several other lower-level crates. If you're attempting something more custom, you might be interested in these:

Getting started

toml [dependencies] nostr-sdk = "0.8" tokio = { version = "1", features = ["full"] }

```rust,no_run use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4};

use nostrsdk::nostr::{Keys, Metadata}; use nostrsdk::nostr::url::Url; use nostr_sdk::{Client, Result};

[tokio::main]

async fn main() -> Result<()> { // Generate new keys let mykeys: Keys = Client::generatekeys(); // // or use your already existing // // From HEX or Bech32 // use nostrsdk::nostr::key::FromSkStr; // let mykeys = Keys::fromskstr("hex-or-bech32-secret-key")?; // // From Bech32 // use nostrsdk::nostr::key::FromBech32; // let mykeys = Keys::frombech32("nsec1...")?; // // From HEX // use std::str::FromStr; // use nostrsdk::nostr::secp256k1::SecretKey; // let secretkey = SecretKey::fromstr("hex-secret-key")?; // let mykeys = Keys::frombech32("nsec1...")?;

// Create new client
let client = Client::new(&my_keys);

let proxy = Some(SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::LOCALHOST, 9050)));

// Add relays
client.add_relay("wss://relay.damus.io", None).await?;
client.add_relay("wss://relay.nostr.info", proxy).await?;
client.add_relay(
    "ws://jgqaglhautb4k6e6i2g34jakxiemqp6z4wynlirltuukgkft2xuglmqd.onion",
    proxy,
).await?;

// Connect to relays and keep connection alive
client.connect().await?;

let metadata = Metadata::new()
    .name("username")
    .display_name("My Username")
    .about("Description")
    .picture(Url::parse("https://example.com/avatar.png")?)
    .nip05("username@example.com");

// Update profile metadata
client.update_profile(metadata).await?;

// Publish a text note
client.publish_text_note("My first text note from Nostr SDK!", &[]).await?;

// Publish a POW text note
client.publish_pow_text_note("My first POW text note from Nostr SDK!", &[], 20).await?;

// Handle notifications
loop {
    let mut notifications = client.notifications();
    while let Ok(notification) = notifications.recv().await {
        println!("{:?}", notification);
    }
}

} ```
