Add the nostr-sdk dependency in your Cargo.toml file:

[dependencies]
nostr-sdk = "0.36"

Alternatively, you can add it directly from git source:

[dependencies]
nostr-sdk = { git = "https://github.com/rust-nostr/nostr", tag = "v0.36.0" }

Import the library in your code:

#![allow(unused)]
fn main() {
use nostr_sdk::prelude::*;
}

The nostr-sdk package is available on the public PyPI:

pip install nostr-sdk 

Alternatively, you can manually add the dependency in your requrements.txt, setup.py, etc.:

nostr-sdk==0.36.0

Import the library in your code:

from nostr_sdk import *

Known issues

No running event loop

If you receive no running event loop error at runtime, add the following line to your code:

import asyncio
from nostr_sdk import uniffi_set_event_loop

uniffi_set_event_loop(asyncio.get_running_loop())

The nostr-sdk package is available on the public npmjs:

npm i @rust-nostr/nostr-sdk

Alternatively, you can manually add the dependency in your package.json file:

{
    "dependencies": {
        "@rust-nostr/nostr-sdk": "0.36.0"
    }
}

WASM

This library to work require to load the WASM code.

Load in async context

const { loadWasmAsync } = require("@rust-nostr/nostr-sdk");

async function main() {
    // Load WASM
    await loadWasmAsync();

    // ...
}

main();

Load in sync context

const { loadWasmSync } = require("@rust-nostr/nostr-sdk");

function main() {
    // Load WASM
    loadWasmSync();

    // ...
}

main();

To use the Kotlin language bindings for nostr-sdk in your Android project add the following to your gradle dependencies:

repositories {
    mavenCentral()
}

dependencies { 
    implementation("org.rust-nostr:nostr-sdk:0.36.0")
}

Import the library in your code:

import rust.nostr.sdk.*

Known issues

JNA dependency

Depending on the JVM version you use, you might not have the JNA dependency on your classpath. The exception thrown will be

class file for com.sun.jna.Pointer not found

The solution is to add JNA as a dependency like so:

dependencies {
    // ...
    implementation("net.java.dev.jna:jna:5.12.0@aar")
}

Xcode

Via File > Add Packages..., add

https://github.com/rust-nostr/nostr-sdk-swift.git

as a package dependency in Xcode.

Swift Package

Add the following to the dependencies array in your Package.swift:

.package(url: "https://github.com/rust-nostr/nostr-sdk-swift.git", from: "0.36.0"),

Add the following code to your package:

nostr_sdk:
    git:
        url: https://github.com/rust-nostr/nostr.git
        ref: v0.36.0
