Discord.zig

A high-performance bleeding edge Discord library in Zig, featuring full API coverage, sharding support, and fine-tuned parsing

  • Sharding Support: Ideal for large bots, enabling distributed load handling.
  • 100% API Coverage & Fully Typed: Offers complete access to Discord's API with strict typing for reliable and safe code.
  • High Performance: Faster than whichever library you can name (WIP)
  • Flexible Payload Parsing: Supports payload parsing through both zlib and zstd*.
  • Proper error handling
const std = @import("std");
const Discord = @import("discord");
const Shard = Discord.Shard;

var session: *Discord.Session = undefined;

fn ready(_: *Shard, payload: Discord.Ready) !void {
    std.debug.print("logged in as {s}\n", .{payload.user.username});
}

fn message_create(_: *Shard, message: Discord.Message) !void {
    if (message.content != null and std.ascii.eqlIgnoreCase(message.content.?, "!hi")) {
        var result = try session.api.sendMessage(message.channel_id, .{ .content = "hi :)" });
        defer result.deinit();

        const m = result.value.unwrap();
        std.debug.print("sent: {?s}\n", .{m.content});
    }
}

    const allocator = gpa.allocator();

    session = try allocator.create(Discord.Session);

    defer session.deinit();

    const env_map = try allocator.create(std.process.EnvMap);

Installation

// In your build.zig file
const exe = b.addExecutable(.{
    .name = "beluga",
    .root_source_file = b.path("src/main.zig"),
    .target = target,
    // just a suggestion, use .ReleaseSafe
    .optimize = optimize,
    // must always be on, hard dependency
    .link_libc = true,
    // self-hosted backed is unstable as of today 2025-05-16, 
    .use_llvm = true,
});

const dzig = b.dependency("discordzig", .{});

exe.root_module.addImport("discord.zig", dzig.module("discord.zig"));

Warning: the library is intended to be used with the latest dev version of Zig.
