Chatwork に Node.js + TypeScript でメッセージを通知する

import { escape } from 'querystring';
import fetch from 'isomorphic-unfetch'

export async function notify(
  api_token: string,
  room_id: string,
  message: string,
  self_unread?: 0 | 1
): Promise<Response> {
  return await fetch(`https://api.chatwork.com/v2/rooms/${room_id}/messages`, {
    method: 'POST',
    headers: {
      'X-ChatWorkToken': api_token,
      'Content-Type': 'application/x-www-form-urlencoded',
    },
    body: `body=${escape(message)}&self_unread=${
      typeof self_unread === 'undefined' ? 1 : self_unread
    }`,
  });
}

# yarn の場合
$ yarn add querystring isomorphic-unfetch

# npm の場合
$ npm install querystring isomorphic-unfetch

async function main() {
  await notify(
    process.env.CHATWORK_API_TOKEN,
    process.env.CHATWORK_ROOM_ID,
    "テストメッセージです。"
  );
}
main();
