Eve

Create a new project with eve and then install the Chat SDK, the Resend adapter, and the development state adapter.

npx eve@latest init my-agent
cd my-agent
npm install @resend/chat-sdk-adapter chat @chat-adapter/state-memory

yarn dlx eve@latest init my-agent
cd my-agent
yarn add @resend/chat-sdk-adapter chat @chat-adapter/state-memory

pnpm dlx eve@latest init my-agent
cd my-agent
pnpm add @resend/chat-sdk-adapter chat @chat-adapter/state-memory

bunx eve@latest init my-agent
cd my-agent
bun add @resend/chat-sdk-adapter chat @chat-adapter/state-memory

Create the Resend adapter with the adapter configuration options. Then create a Chat SDK channel with the adapter, a username for the bot, and an adapter state. streaming should be set to false as emails can only deliver one message per turn.

Export the channel object and the framework will integrate it automatically.

import { createResendAdapter } from '@resend/chat-sdk-adapter';
import { chatSdkChannel } from 'eve/channels/chat-sdk';
import { createMemoryState } from '@chat-adapter/state-memory';

export const resendAdapter = createResendAdapter({
  fromAddress: 'bot@example.com',
  fromName: 'My Bot',
});

export const { bot, channel, send } = chatSdkChannel({
  adapters: { resend: resendAdapter },
  userName: 'My Bot',
  state: createMemoryState(),
  streaming: false,
});

export default channel;

Register handlers for incoming messages. onNewMention event fires when a new thread starts and onSubscribedMessage fires for follow-up emails in threads you are already subscribed to.

bot.onNewMention(async (thread, message) => {
  await thread.subscribe();
  await send(message.text, { thread });
});
bot.onSubscribedMessage(async (thread, message) => {
  await send(message.text, { thread });
});

Threading is handled by the Chat SDK adapter.

Eve registers adapter endpoints at /eve/v1/resend. Edit your webhook for email.received events to point to this endpoint.
