catnip

A Discord API wrapper in Java. Fully async / reactive, built on top of vert.x.

We have a Discord! https://discord.gg/kCsBCjK

Installation

If this is too hard for you and / or you use gradle, get it on Jitpack here: https://jitpack.io/#mewna/catnip

Basic usage

This is the simplest possible bot you can make right now:

final Catnip catnip = Catnip.catnip().token(System.getenv("TOKEN"));
catnip.eventBus().<Message>consumer(DiscordEvent.MESSAGE_CREATE, event -> {
    final Message msg = event.body();
    if(msg.content().equalsIgnoreCase("!ping")) {
        catnip.rest().channel().sendMessage(msg.channelId(), "pong!");
    }
});
catnip.startShards();

catnip returns CompletableFutures from all REST methods. For example, editing your ping message to include time it took to create the message:

final Catnip catnip = Catnip.catnip().token(System.getenv("TOKEN"));
catnip.eventBus().<Message>consumer(DiscordEvent.MESSAGE_CREATE, event -> {
    final Message msg = event.body();
    if(msg.content().equalsIgnoreCase("!ping")) {
        final long start = System.currentTimeMillis();
        catnip.rest().channel().sendMessage(msg.channelId(), "pong!")
                .thenAccept(ping -> {
                    final long end = System.currentTimeMillis();
                    catnip.rest().channel().editMessage(msg.channelId(), ping.id(),
                            "pong! (took " + (end - start) + "ms)");
                });
    }
});
catnip.startShards();
