Discord4J

Discord4J

Discord4J is a fast, powerful, unopinionated, reactive library to enable quick and easy development of Discord bots for Java, Kotlin, and other JVM languages using the official Discord Bot API.

🏃 Quick Example

In this example for v3.3, whenever a user sends a !ping message the bot will immediately respond with Pong!.

Make sure your bot has the Message Content intent enabled in your developer portal.

public class ExampleBot {

    public static void main(String[] args) {
        String token = args[0];
        DiscordClient client = DiscordClient.create(token);
        GatewayDiscordClient gateway = client.login().block();

        gateway.on(MessageCreateEvent.class).subscribe(event -> {
            Message message = event.getMessage();
            if ("!ping".equals(message.getContent())) {
                MessageChannel channel = message.getChannel().block();
                channel.createMessage("Pong!").block();
