Hello, rust-nostr!

Now that you’ve installed the SDK, it’s time to write your first nostr program.

Generate random keys and construct the client

Rust

let keys: Keys = Keys::generate();
let client = Client::new(keys);

Python

keys = Keys.generate()
client = Client(keys)

JavaScript

let keys: Keys = Keys.generate();
let signer = NostrSigner.keys(keys);
let client = new Client(signer);

Kotlin

//val keys = Keys.generate()
//val client = Client(signer = keys) // TODO: uncomment when fixed

TODO

Add some relays and connect

Rust

client.add_relay("wss://relay.damus.io").await?;

client.connect().await;

Python

await client.add_relay("wss://relay.damus.io")

await client.connect()

JavaScript

await client.addRelay("wss://relay.damus.io")

await client.connect();

Kotlin

//client.addRelay("wss://relay.damus.io")

//client.connect()

Publish a text note

Rust

let builder = EventBuilder::text_note("Hello, rust-nostr!", []);
client.send_event_builder(builder).await?;

Python

builder = EventBuilder.text_note("Hello, rust-nostr!", [])
await client.send_event_builder(builder)

JavaScript

let builder = EventBuilder.textNote("Hello, rust-nostr!", []);
await client.sendEventBuilder(builder);

Kotlin

//val builder = EventBuilder.textNote("Hello, rust-nostr!", listOf())
//client.sendEventBuilder(builder)

Full example

Rust

use nostr_sdk::prelude::*;

pub async fn hello() -> Result<()> {
    let keys: Keys = Keys::generate();
    let client = Client::new(keys);

    client.add_relay("wss://relay.damus.io").await?;

    client.connect().await;

    let builder = EventBuilder::text_note("Hello, rust-nostr!", []);
    client.send_event_builder(builder).await?;

    Ok(())
}

Python

from nostr_sdk import Keys, Client, EventBuilder


async def hello():
    keys = Keys.generate()
    client = Client(keys)

    await client.add_relay("wss://relay.damus.io")

    await client.connect()

    builder = EventBuilder.text_note("Hello, rust-nostr!", [])
    await client.send_event_builder(builder)

JavaScript

import {Keys, Client, EventBuilder, NostrSigner} from "@rust-nostr/nostr-sdk";

export async function hello() {
    let keys: Keys = Keys.generate();
    let signer = NostrSigner.keys(keys);
    let client = new Client(signer);

    await client.addRelay("wss://relay.damus.io")

    await client.connect();

    let builder = EventBuilder.textNote("Hello, rust-nostr!", []);
    await client.sendEventBuilder(builder);
}

Kotlin

import rust.nostr.sdk.*

suspend fun hello() {
    //val keys = Keys.generate()
    //val client = Client(signer = keys) // TODO: uncomment when fixed

    //client.addRelay("wss://relay.damus.io")

    //client.connect()

    //val builder = EventBuilder.textNote("Hello, rust-nostr!", listOf())
    //client.sendEventBuilder(builder)
