Overview - Corsair

Use Chatwork through Corsair: one client, typed API calls, local DB sync. What you get:

30 typed API operations
7 synced entities (accounts, files, incomingRequests, members, messages, rooms, and 1 more) for fast .search() / .list()

Setup

Install

npm install corsair @corsair-dev/chatwork

yarn add corsair @corsair-dev/chatwork

pnpm install corsair @corsair-dev/chatwork

bun add corsair @corsair-dev/chatwork

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { chatwork } from '@corsair-dev/chatwork';

export const corsair = createCorsair({
	plugins: [
		chatwork({
			authType: 'oauth_2',
		}),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

Multi-tenancy is the default — scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

OAuth 2.0 (Recommended)
API Key

Open hub.corsair.dev, navigate to your project, and enter the client ID and client secret from your Chatwork OAuth app.

chatwork({
	authType: 'oauth_2',
})

More: OAuth 2.0

No setup required yet. When you make your first request as a tenant, Corsair prompts for the API key.

chatwork()

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'chatwork',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

List rooms

const tenant = corsair.withTenant('acme');
await tenant.chatwork.api.rooms.list({});

Send a message to a room

const tenant = corsair.withTenant('acme');
await tenant.chatwork.api.messages.send({ room_id: 123456, body: 'Hello from Corsair!' });

See the full list on the API page.

Query synced data

Search synced rooms without hitting the Chatwork API.

const tenant = corsair.withTenant('acme');
const rows = await tenant.chatwork.db.rooms.search({
	data: { type: 'group' },
	limit: 20,
});

Synced entities: accounts, files, incomingRequests, members, messages, rooms, tasks. See Database for filters and operators.
