🌌 EasyNostr

EasyNostr is a high-level, developer-friendly Rust library designed to simplify the development of Nostr applications. It wraps the powerful nostr-sdk to provide a clean, intuitive API for common operations like identity management, social feeds, and encrypted messaging.

🚀 Key Features

• Identity Management: Simple handling of keys (nsec/npub).
• Social Connectivity: Follow users and manage contact lists.
• Rich Feeds: Access follow-based timelines, global discovery, and hashtag-based searches.
• Encrypted Messaging: Secure NIP-17 direct messages.
• Extensible Architecture: Clean separation between protocol logic (NIPs) and high-level functions.

📦 Installation

Add easy-nostr and its core dependencies to your Cargo.toml:

[dependencies]
easy-nostr = { path = "." } # Use the crate path
tokio = { version = "1.48.0", features = ["full"] }
anyhow = "1.0.100"

🛠️ Usage Guide

1. Initialization & Connection

Create a new instance and connect to your preferred relays.

use easy_nostr::EasyNostr;
use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()> {
    // Initialize with your private key (nsec)
    let secret_key = "nsec1..."; 
    let en = EasyNostr::new(secret_key).await?;

    // Add relays to connect to the network
    en.add_relays(vec![
        "wss://relay.damus.io",
        "wss://nos.lol",
        "wss://relay.primal.net"
    ]).await?;

    println!("Connected to Nostr!");
    Ok(())
}

📝 Publishing Content

Post a simple text note (Kind 1) to the network.

let event_id = en.post_text("Building with EasyNostr is awesome!").await?;
println!("Successfully posted! Event ID: {}", event_id);

📰 Social Feeds

Timeline (Followed Users)

Fetch posts from a specific list of public keys.

let follow_list = vec!["npub1...".to_string(), "npub2...".to_string()];
match en.get_timeline(follow_list).await {
    Ok(posts) => {
        for post in posts {
            println!("@{} says: {}", post.author, post.content);
        }
    }
    Err(e) => eprintln!("Failed to load timeline: {}", e),
}

Discovery (Global Feed)

Get recent random posts from connected relays.

let global_posts = en.get_random_posts().await?;

Hashtag Search (NIP-12)

Search for posts containing specific hashtags.

let tags = vec!["bitcoin".to_string(), "rust".to_string()];
let filtered_posts = en.get_posts_by_hashtags(tags).await?;

👥 Contacts & Following

Follow a User

en.create_contact("npub1...", Some("Alice".to_string())).await?;

Retrieve Contact List

let contacts = en.get_contacts().await?;

🔒 Private Messaging (NIP-17)

Send a Message

en.send_private_message("npub1...", "Hello, this is a secret!").await?;

Retrieve Conversations

let history = en.get_private_messages("npub1...").await?;
