Quick Start Examples

JavaScript

import { createClient } from 'matrix-js-sdk';

const client = createClient({
    baseUrl: "https://matrix.example.com",
    accessToken: "your-access-token",
    userId: "@user:example.com"
});

client.startClient();
client.on("Room.timeline", (event, room) => {
    if (event.getType() === "m.room.message") {
        console.log(`${event.getSender()}: ${event.getContent().body}`);
    }
});

Python (nio)

from nio import AsyncClient, RoomMessageText

async def main():
    client = AsyncClient("https://matrix.example.com", "@user:example.com")
    await client.login("password")

    client.add_event_callback(message_callback, RoomMessageText)
    await client.sync_forever()

async def message_callback(room, event):
    print(f"{event.sender}: {event.body}")

Rust

use matrix_sdk::{Client, config::SyncSettings, ruma::events::room::message::RoomMessageEventContent};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let client = Client::builder()
        .homeserver_url("https://matrix.example.com")
        .build()
        .await?;

    client.login_username("user", "password").send().await?;
    client.sync(SyncSettings::default()).await?;
    Ok(())
}
