Generic Discord API client for webhooks, bot messaging, and embeds. Runtime-agnostic via injectable fetch and clock. Maps every documented Discord failure mode to a stable DISCORD.* error code and emits OpenTelemetry counters and histograms for every request.

Quick Start

import { DiscordBotClient, DiscordWebhook } from "@suaveplan/discord-client";

const bot = new DiscordBotClient({ token: process.env.DISCORD_BOT_TOKEN! });

const hook = new DiscordWebhook({
  webhookUrl: "https://discord.com/api/webhooks/123/abc",
});
await hook.sendText("hello from a webhook");

Injectable Fetch & Clock

Both DiscordBotClient and DiscordWebhook accept fetch and clock injectables — pass deterministic stubs in tests, omit them in production to use globalThis.fetch and Date.now.

import { DiscordBotClient, type FetchLike } from "@suaveplan/discord-client";

const stubFetch: FetchLike = async () => ({
  ok: true, status: 200, statusText: "OK",
  headers: { get: () => null },
  text: async () => "", json: async () => ({ id: "1", channelId: "1", content: "x", timestamp: "" }),
});

new DiscordBotClient({
  token: "abc",
  fetch: stubFetch,
  clock: () => 1_700_000_000_000,
});

OTel Metrics
